01What we build
The systems a business actually runs on.
Every service here is something we already run in production for our own companies — not a slide. You get the same code, the same infrastructure habits and the same person accountable for it.
E-commerce & logistics
Storefronts, wholesale and dropshipping, COD wallets, courier integrations and cross-border fulfillment.
Discuss thisTracking & growth
Server-side tracking that survives ad blockers: Meta and TikTok Conversions API, server-side GA4 and clean GTM setups.
Discuss thisBusiness automation & AI
Bots, workflows and AI agents that take repetitive work off your team — WhatsApp assistants, browser automation, content pipelines.
Discuss thisData, BI & analysis
ETL pipelines, dashboards and the analysis behind decisions — P&L, valuation, forecasting and honest testing.
Discuss thisInfrastructure & security
VPS and dedicated servers, CI/CD deploys, Cloudflare, backups and hardening — and someone watching it after launch.
Discuss thisTech consulting
Architecture reviews, stack choices, cost cuts and a straight answer on what to build first — before you spend on it.
Discuss thisAPIs & microservices
Standalone services with their own consoles and billing — like our address validation API — that plug into any stack.

02Who I am
Hi, I'm Talha.
I build the systems businesses run on — and I run businesses too.
I'm Syed Talha Islam, a full-stack developer, data and business analyst, and digital marketer from Dhaka. I started coding Android apps in 2018, joined Cosmic Trading in 2020, and spent the next years building the platforms a 16-person team runs on every day.
Along the way I founded my own brands, managed operations as a COO, spent over $32K on ads with my own hands, and became co-owner and CEO of BetaBroad. Solustation is where all of that comes together.
When you work with Solustation, you work with me — the person who scopes your project is the person who builds it, answers your messages and stays on after launch.

- Honest scoping.If something won't pay off, I'll say so before you spend on it.
- I stay after launch.Your system keeps an owner who knows it inside out.

Syed Talha Islam · Full-stack developer, business analyst & founder
Client and company code stays private, so most of my work ships to the live sites above. My profile has my public repositories, the full project list and my contribution streak.
- 2018
Started coding
Built Android apps and practiced logic and UI/UX design — the habit of shipping whole things, not parts, started here.
- 2020
Joined Cosmic Trading
Started on the business side of China-to-Bangladesh trade — operations, data and the problems software should solve.
- 2023
Founded Menev
Launched a men's fashion brand and ran it end to end: product, storefront, marketing and operations.
- 2024 – 2025
Architected the CosmicTRD ecosystem

BSc in Data Science at United International University — with a capstone on decision-making AI for Dhaka traffic and an ML address validator in production.
03Business first
Engineer by trade. Operator by habit.
Most developers build what's on the ticket. I've managed the business, read the numbers and paid for the ads — so I build what moves revenue. Five seats at your table, one person.
Fewer handoffsStrategy, build and growth sit with one accountable person.
Features tied to revenueEvery item in scope has a business reason you can read.
Tracking from day oneYou'll know what's working the week you launch.
Numbers you understandReports in plain language, not developer jargon.
Need someone who gets the business side? Tell us the goal; we'll design the system around it.
04Solutions by business
Pick your kind of business. Here's what we'd build.
We start from how your business makes money, then build the system around it. These are the setups we already run for real companies.
Your store, payments, couriers and ads working as one system.
The problem. Brands lose margin in the gaps: orders typed by hand, couriers booked one by one, ad platforms that never learn which orders were delivered.
- A fast storefront (custom or WooCommerce) built for mobile and COD
- Automatic courier booking, tracking and COD reconciliation
- Server-side tracking so ads optimise for delivered orders
- Inventory, returns and a dashboard your team actually uses
For Facebook and Instagram sellers who outgrew the inbox.
The problem. Orders live in Messenger threads, numbers live in a notebook, and nobody knows which ad actually made money.
- An order panel that replaces spreadsheets and chat screenshots
- Courier integration with Pathao, Steadfast, RedX and CarryBee
- Pixel and Conversions API that report real, delivered sales
- A simple store or landing page when you are ready to sell beyond chat
Booking, tracking, wallets and remittance — for couriers and 3PLs.
The problem. Logistics runs on status updates and money movement. Both break when they live in different tools.
- Seller apps, public tracking pages and staff consoles
- COD wallets, remittance ledgers and invoices
- Courier API integrations and automated escalations
- Address validation that cuts failed deliveries
Sourcing, B2B ordering and cross-border payments in one place.
The problem. Importers juggle supplier links, currency rates, shipping lots and customer balances across chat and spreadsheets.
- B2B wholesale catalogues with supplier sourcing (1688 / OTCommerce)
- Multi-currency wallets, escrow and payment gateways
- Order, shipment and lot tracking from China to the customer
- Dropshipping and group-buy models on the same backbone
From idea to a paying product, without a tech team to hire first.
The problem. Founders need something real in front of customers fast — and a codebase that still holds up after the first hundred users.
- MVP scoping that cuts the build to what proves the business
- Multi-tenant apps with billing, roles and onboarding
- Analytics and tracking from day one
- Hosting, CI/CD and monitoring so you can sleep after launch
Bookings, follow-ups and reports that run themselves.
The problem. Agencies, clinics, schools and offices lose hours to the same manual steps every week.
- Booking, enquiry and CRM tools built around how you work
- WhatsApp and email automation for reminders and follow-ups
- AI assistants that answer common questions
- Dashboards that show what is working at a glance
05E-commerce, end to end
From ad click to cash in hand — one connected loop.
Most stores are five tools that don't talk. We build the whole loop, so every delivered order makes the next ad cheaper.
- StorefrontCustom PHP, Next.js or WooCommerce — fast on 3G, built for COD.
- Orders & stockConfirmation calls, fraud checks, inventory and returns in one panel.
- CouriersPathao, Steadfast, RedX, CarryBee, Delhivery, Shiprocket — booked and tracked automatically.
- MoneyCOD remittance matched to every order; bKash, Nagad, EPS and card payments.
- GrowthServer-side tracking, GA4 and dashboards that show profit, not just sales.

- Ad clickMeta · TikTok · Google
- Storefast, mobile, COD-ready
- Orderchecked, confirmed, stocked
- Courierbooked automatically
- Cash inCOD reconciled to the taka

06Why these exist
I build what I needed first.
Every product on the line started as a problem in a business I was running. By the time you describe yours, there's a good chance I've already paid for the same mistake.
Delivrodelivro.app
The problem I had
I ran $32K+ of Meta ads for cash-on-delivery stores. Many of the purchases Meta learned from were later cancelled or returned, so the ads kept finding the wrong buyers.
What I built
I built a tracker that reports a purchase in real time or only when the courier confirms delivery, so ads learn from orders that actually paid.
Solustation Addressaddress.solustation.site
The problem I had
Parcels were coming back because addresses were incomplete: no pincode, a vague landmark, the wrong district.
What I built
I trained a model on real courier return data that scores an address and fills in the gaps before a parcel is booked.
CosmicTRDcosmictrd.com
The problem I had
A trading business running on chat threads and spreadsheets can only grow as far as the people who remember everything.
What I built
I designed one relational core, 180+ tables, that 12+ platforms and a 16-person team now share every day.
Skydropskydrop.online
The problem I had
Shipping between Bangladesh and India meant two couriers, two currencies and endless manual follow-ups.
What I built
We built two-leg consignments, a COD wallet with remittance, and automated courier escalations into one platform.
07The Solustation line
Every stop is a business we run.
Solustation is the interchange. Each station is a live company or product built and powered from here. Pick a stop to see what's inside.
The interchange
Solustation
My own technology company. It designs, builds, hosts and automates every platform on this line — and takes on outside projects with the same standards.

08Selected work
Live products, not mockups.
Commercial source code stays private. Every link here is a real system in production.
Skydrop — a courier network between two countries
A Turborepo monorepo behind five production apps: the landing site, public tracking, the seller app, a white-label reseller portal and the staff console. Money moves through a COD wallet and remittance ledger; parcels move through Delhivery with automated escalations.

Delivro — tracking that knows when the parcel arrived
Bangladeshi sellers lose ad signal to blockers and cancelled COD orders. Delivro sends events from the server, in real time or only on courier-confirmed delivery, so Meta and TikTok optimise for orders that actually pay.

10Under the hood
Shipped like infrastructure.
Every system we run goes out the same way: tested, deployed from one branch, health-checked and easy to roll back. Yours gets the same pipeline.
- CI/CD from mainEvery merge is built, checked and deployed automatically.
- Health checks & monitoringEach app reports in; problems surface before customers notice.
- One-step rollbacksPrevious builds stay on the server, so a bad release is minutes from undone.
- Hardened by defaultCloudflare in front, least-privilege access, backups and HTTPS everywhere.
An example deployment log: code is pushed, tests and builds run, the release goes to production and passes its health check.

11The first call
The first call is about your business, not my tech stack.
Here's what I'll ask before anyone writes code. Have rough answers ready and we'll get further in thirty minutes than most projects get in a month.
- 01What does one delivered order earn you after ads and courier fees?
- 02Which courier delivers best in which district?
- 03Where does your team copy and paste every single day?
- 04Which ad set brings delivered orders, not just placed ones?
- 05What breaks if your orders double next month?
- 06What would you stop doing tomorrow if a system did it for you?
And sometimes I'll tell you what not to build yet.
Talha · Solustationusually replies personally
Example conversation- We want a new website for our store.
- Happy to help. Quick one first: how many orders a day, and how many come back?
- Around 80 a day. Maybe a quarter get returned.
- Then the website isn't your biggest leak. Those returns are teaching your ads to find more people who return. Let's fix tracking and address checks first, then build the new store on top.
- That's not what the last agency told us.
- I've paid for those returns in my own stores. I'd rather you didn't.

Before you message.
Yes. Solustation was set up to power my own ventures and to build for clients — startups, sellers, agencies and established businesses, in Bangladesh, India and abroad.
Anything where software has to run a real operation: e-commerce and wholesale, logistics and courier integrations, SaaS products, server-side tracking, automation and internal tools, dashboards and data pipelines.
After the discovery call you get a written scope with milestones and a quote for each. You know the cost of every stop before it starts. Ongoing hosting and support are quoted separately.
Yes. We start with an audit of the code, hosting and data, fix what's risky first, and then improve it in steps — without rewriting what already works.
If you want us to. We run servers, deploys, backups, monitoring and security for our own platforms and can do the same for yours — or hand everything over cleanly to your team.
English and Bangla. We're in Dhaka (GMT+6) and work remotely with clients in other time zones.
