Are you available for freelance or contract work?

Yes — I take on remote freelance and contract engagements worldwide. I work with clients in the US, UK, EU, Australia, and the Middle East. Reach out via email to discuss your project.

What's your tech stack?

Frontend: React, Next.js, TypeScript, Tailwind CSS, Shadcn UI, Redux. Backend: Node.js, Express, NestJS, Prisma. Databases: PostgreSQL, MongoDB, MySQL, Redis. DevOps: AWS (EC2, S3), Docker, GitHub Actions, NGINX, PM2.

What kind of projects do you specialize in?

Custom CRM, ERP, and EMS platforms; EdTech and recruitment portals; SaaS MVPs; AI-integrated web apps; and high-performance REST and GraphQL APIs. I have production experience shipping ed-tech platforms used by 1000+ concurrent users.

Where are you located and what's your timezone?

I'm based in Dhaka, Bangladesh (GMT+6). I have significant overlap with Europe, the Middle East, and Asia-Pacific business hours, and I regularly work async with US-based teams.

Do you take on fixed-price projects or hourly engagements?

Both. Fixed-price works well for clearly scoped MVPs and feature builds. Hourly or monthly retainers fit ongoing development, maintenance, and product partnerships. I'll recommend the model that fits your project after a short scoping call.

How quickly can you start?

Typically within 1–2 weeks for new engagements, sometimes sooner for short-scope work. Send a brief and I'll respond within 24 hours.

দর্জিখাতা — Tailor Shop Manager

Bangla-first, multi-tenant SaaS for Bangladeshi tailor shops: custom measurement fields, order workflow, and dues — built for owners who may not read fluently.

Multi-tenant from the first migration — composite uniqueness, one auth seam
Shop-defined garments and measurement fields stored as JSONB, no migration per shop
Measurements frozen onto each order, so history never rewrites itself

Vaultly — Secure File Storage

File storage where a 500 MB upload costs the server two small JSON requests: the browser sends chunks straight to object storage, and every file is private until you publish a link you can take back.

Presigned S3 multipart uploads: bytes go browser to storage, three parts in flight, per-part retry
Post-upload verification — real size checked against the declared size, magic bytes sniffed from a 4 KB range read
Executables rejected on signature, including the Mach-O/Java 0xCAFEBABE collision
