Websites, mobile apps, AI automation, enterprise systems and security — built personally on proven open-source technology, including national government systems. Not resold, not outsourced, not templated.
Open any card to see the tools it's actually built on — not just what it's called.
From a company site that ranks on Google to a full customer portal with payments, dashboards and admin panels — fast, mobile-first, and built to be found.
Read moreShow lessMost business websites in Bangladesh are built to be looked at once and forgotten. These are built to work: SEO-ready structure, sub-second load times, responsive on the cheapest Android phone your customer owns, and a backend you can grow into — user accounts, online payments (bKash, Nagad, SSLCommerz, cards), booking, e-commerce, multi-language Bangla/English.
Real-time, offline-capable apps — delivery tracking, chat, field tools, customer apps — that stay fast on real Bangladeshi networks.
Read moreShow lessApps here fail for one reason: they're built assuming perfect internet. These assume a bad-network day — offline-first data, background sync, push notifications, live location and real-time updates over WebSockets. One codebase for Android and iOS where it makes sense, native where it doesn't.
AI that answers your customers, reads your documents, and does the repetitive work — on your own data, in Bangla and English.
Read moreShow lessNot a demo — deployed AI. Customer-support chatbots trained on your own catalog, policies and FAQs (website, WhatsApp, Messenger). Document intelligence: feed in contracts, reports or forms and get summaries or drafted replies. Built on retrieval-augmented generation (RAG) so answers come from your documents, not the internet's imagination — with the option to run models fully on your own servers.
The systems that run an organization — inventory, HR, approvals, reporting — without the SAP-sized price tag.
Read moreShow lessThe same workflows large organizations run on SAP and Oracle — inventory, procurement, HR & payroll, accounting, multi-level approvals, reporting — can be built on mature open-source platforms or custom-developed, at a fraction of the cost and fully owned by you. Role-based access, audit logs, and the reporting your management actually asks for.
Data scattered across Excel files, databases and PDFs, turned into live dashboards and searchable knowledge.
Read moreShow lessThe pipeline: pull data from every source (databases, APIs, spreadsheets, even scanned documents), move it reliably, and land it somewhere queryable. Apache NiFi and Airbyte for ingestion, Kafka for real-time streams, Spark when the volume gets serious, OpenSearch for full-text search, and Apache Superset for dashboards your management can open in a browser — no per-seat BI license, ever.
Hardened servers, monitored networks, encrypted backups and private VPNs — so the bad-hour phone call never comes.
Read moreShow lessSecurity is not a product you buy; it's how the system is built. Network intrusion detection with Suricata, database activity monitoring, WireGuard/OpenVPN for secure remote access, server hardening, and SQL-injection-proof application design. Reliability is the other half: automated encrypted backups with Bacula and Restic (tested restores, not just backups), S3-compatible private object storage with MinIO, and monitoring that alerts before users notice.
Every tool is a deliberate choice, not a default.

Government-scale systems where downtime isn't a metric, it's an incident — including national-level work for the Bangladesh Technical Education Board (BTEB), kept short here under employer confidentiality.

Joined as a developer, promoted to Team Lead within the engagement — AI, web and mobile product lines delivered independently.
Most software vendors in Bangladesh quietly rent you technology: per-user licenses, per-year renewals, and a dependency you can never leave. I build on the open-source stack that global enterprises actually run — Kafka moves data at LinkedIn, MinIO stores it at Fortune-500 scale, Superset powers dashboards at Airbnb. You own every line of it, and your only recurring cost is hosting.
The same five steps every time, in order — because the order is what keeps things calm.
You describe the problem in plain language — Bangla or English, doesn't matter. No requirement documents needed to start.
A written proposal: what will be built, on what, by when, for how much. If a ready-made tool solves it cheaper, you'll be told so.
Weekly working demos, not monthly status reports. You see the real system early enough to change your mind cheaply.
Monitoring, backups and rollback are configured before go-live, not after the first incident.
Maintenance and support terms agreed up front. When something breaks at a bad hour, you have a phone number, not a ticket queue.
It depends on what the website has to do. A professional company site is a different project from an e-commerce platform with payments and inventory. You'll get a fixed written quote after one conversation — free, no obligation.
Yes — bKash, Nagad, SSLCommerz and international card gateways are all standard integrations here.
It's software that answers customer questions automatically — on your website, WhatsApp or Messenger — using your own product and policy information. If your team answers the same 20 questions every day, it usually pays for itself.
The licensed giants are excellent — and priced for multinationals. Open-source equivalents deliver the same core capability with zero license fees and no vendor lock-in. You own everything that's built.
Yes. Every project ships with a support arrangement in writing — updates, backups, monitoring, and a real human to call.
Yes. Everything — including AI — can run entirely on infrastructure you own, with nothing leaving your network. This matters for organizations handling sensitive data, and it's a specialty here.
One email or one call. Explain what's broken, missing, or slow — in Bangla or English — and you'll get back a straight answer: what to build, what it takes, and whether you even need it.
