One developer, the whole product
Custom web applications, SaaS platforms, AI features, and performance work. I scope it, build it, deploy it, and hand it over with documentation your team can run with.
Custom web applications
Founders who need a product, not a prototype.
Your product, built from spec to production by one developer who owns the whole stack.
Interface, API, database, and hosting, designed together so nothing falls between the gaps. Built on React, Next.js, TypeScript, and Node.js, and shaped to handle real traffic from the first deploy.
- Full-stack development
- Responsive interface
- Database architecture
- Deployment and hosting
SaaS platforms
Teams launching a paid product or replacing a manual process.
Subscription products with auth, billing, roles, and dashboards that hold up as you grow.
Multi-tenant data models, secure authentication, payment integration, and admin tooling. I have shipped this shape of product several times and know where the sharp edges are.
- Authentication and roles
- Payments and subscriptions
- Admin dashboards
- REST API development
AI features in real products
Products where a smart feature would remove real friction.
LLM-powered features with rate limits, fallbacks, and honest error handling built in.
Natural-language input, document extraction, retrieval over your own data, and assistants that answer from real records. Every model call sits behind server-side limits, so an AI feature never becomes an unbounded bill.
- LLM integration
- Retrieval over your data
- Structured extraction
- Background processing
Performance rescues
Existing products that feel slow or score badly in search.
Slow Next.js and React apps profiled, fixed, and measured.
I find the real bottleneck rather than guessing: render paths, image budgets, bundle weight, caching, and database queries. Typical result is a multi-second load brought under 1.5 seconds with a Lighthouse score above 90.
- Performance audit
- Core Web Vitals work
- Query and cache optimisation
- Architecture cleanup
How a project runs
Most projects go from kickoff to production in four weeks. You see progress every day, not at the end.
Week 1
Scope and foundation
We talk through the problem, I ask the uncomfortable questions, and by the end of the week you have a roadmap, a repository, and a first working demo.
Week 2
Core build
API, interface, and integrations take shape. You see progress daily and can steer as we go.
Week 3
Refinement
Testing, performance tuning, mobile polish, and a proper feedback round. Good enough is not the bar.
Week 4
Handover
Production deploy, documentation, and a walkthrough so your team can take it from here. I stay around for questions.
The stack
Proven tools chosen for longevity, so the next developer can pick the code up without a handover call.
- Front end
- Next.js, React, TypeScript, Tailwind CSS
- Back end
- Node.js, Express, NestJS, REST, WebSockets
- Data
- PostgreSQL, MongoDB, Redis, Prisma
- AI
- Gemini and OpenAI APIs, vector search, background workers
- Shipping
- Docker, Nginx, GitHub Actions, DigitalOcean, Vercel
Questions clients ask
How much does a project cost?
It depends on scope, which is why the first conversation is free and carries no commitment. Tell me what you have in mind, even roughly, and I will tell you honestly what it takes in time and money before you decide anything.
How long does a typical project take?
Most projects go from kickoff to production in about four weeks. Bigger platforms take longer and small fixes take less, but you will always know the timeline before we start and see progress weekly.
Who am I actually working with?
Me. No project managers, no outsourcing, no middlemen. I scope it, build it, deploy it, and answer your questions directly.
Can you work with an existing codebase or team?
Yes. Performance rescues and feature work on existing products are a regular part of what I do. I match your conventions and document what I change so your developers can pick it up without a handover call.
Who owns the code?
You do, completely. Clean architecture, typed end to end, with documentation written for the next developer. You are never locked into me.
What happens after launch?
Every project ends with docs, a handover, and post-launch support for questions and fixes. If you want ongoing work after that, we set it up on terms that suit you.
Which time zones do you work with?
I am in Dhaka (GMT+6) and keep overlap with EU, UK, US, and Asian teams. Replies usually land within a few hours.
Ready to scope your project?
Tell me what you are building, even roughly. The first conversation is free and I will tell you honestly what it takes.
