Everything you need to launch and grow a software product
One senior engineer, accountable for the whole stack. No hand-offs, no agency overhead, no surprises.

Complete web applications — modern frontend, robust backend, database and cloud deployment — delivered as one accountable engagement.
Learn moreSaaS Products
Multi-tenant SaaS platforms with subscription billing, analytics and infrastructure designed to scale from first customer to thousands.
Learn moreBackend & APIs
Scalable REST APIs, microservices and real-time systems in TypeScript — the core competence behind everything else I build.
Learn moreStartup MVPs
A focused, launch-ready product in 4–8 weeks — built on a foundation that will not need rewriting when you find traction.
Learn moreIntegrations & Automation
Connect payments, CRMs, project tools and custom APIs so data flows automatically and your team stops doing manual work.
Learn moreAI Integration
Practical AI features on top of your own data — RAG search, support assistants and LLM automation — engineered for accuracy and cost control.
Learn moreBackend-grade engineering across the whole stack
Most full-stack developers are frontend developers who can write an API. I'm the opposite: a backend engineer who has spent years on scalability, data modelling, payments and infrastructure — and who also builds fast, responsive Next.js frontends. That means your product looks good and survives real traffic.

Frequently asked questions
Do you work with clients outside Bangladesh?
Yes. I work remotely with startups and businesses worldwide, overlapping with US, UK and EU hours as needed. All communication is in English via Slack, email or video calls.
What does it cost to build a SaaS MVP or web app?
Scope drives price. A focused MVP typically starts in the low thousands (USD) and a full SaaS platform with billing, dashboards and integrations is quoted per milestone. You get a fixed, written estimate before any work starts — no surprises.
How long does a typical project take?
A landing page or API integration: 1–2 weeks. An MVP: 4–8 weeks. A full SaaS product: 2–4 months delivered in milestones so you see working software every week or two.
Which tech stack do you use?
TypeScript end-to-end: Next.js and React on the frontend, Node.js with NestJS on the backend, PostgreSQL/MongoDB/Redis for data, and AWS or GCP with Docker for infrastructure. This stack is proven, hireable and easy to maintain long-term.
Can you take over an existing codebase?
Yes. I regularly join projects mid-flight to fix performance issues, stabilise infrastructure, add features or migrate to a scalable architecture. I start with a short code audit so you know exactly what you're getting into.
Do you offer support after launch?
Yes. Every project includes a hand-off period, and I offer monthly maintenance and retainer plans for ongoing development, monitoring and priority fixes.
How do we get started?
Send a short message through the contact form or WhatsApp. I'll reply within 24 hours, ask a few questions, and — if it's a fit — send a written proposal with scope, timeline and price.
Have a project in mind?
Tell me what you're building. I'll reply within 24 hours with honest feedback and, if it's a fit, a written proposal with scope, timeline and price.
