Open for work · Chittagong, Bangladesh

Hi, I'm Tawchiful. I build whole products, front to back.

Tawchiful Islam is a full-stack developer based in Chittagong, Bangladesh. React and Next.js on the front, Node, Express and MongoDB behind it. I care about clean architecture, readable code and interfaces that feel good to use.

Selected work

Things I've built, and why.

Case studies rather than a showcase. Each one started with a real problem.

Case study 1 of 4: Brawnix

01 / 04
  • Internship capstone

    LLM Usage Metering and Billing Service

    A multi-tenant backend that tells every customer how much they've used, what it costs, and whether they've hit their plan limit.

    AI token counts are simulated and Stripe runs in test mode only.

    Embeddable Widget and Lead-Capture Platform

    Customers build a form widget, paste one script tag into any site, and collect submissions in a dashboard.

    Geo lookups and email are mocked by default, and rate limit counters live in the memory of one server process.

    Social Media Studio

    Turns one blog post into a social campaign: a variant per platform, a human approves each one, then a scheduler publishes.

    Variants come from templates, not an AI model, and the API has no authentication.

About

Self-taught, and building things that hold up.

I'm a self-taught full-stack developer from Chattogram (Chittagong). My formal programming journey began in 2025, though I'd been absorbing how software is made long before I wrote my first line of code. Since then I've built and deployed complete products: a gym management platform, a doctor appointment system, a travel discovery platform with an AI assistant, and a crowdfunding app.

What I enjoy most is the moment a hard problem finally makes sense. I try to build the parts users never see but always depend on: role-based access, payments, scheduled jobs, and graceful handling of retries and dropped connections.

In 2026 I completed the FlyRank AI Internship Program in the Backend AI Engineering track. Each of my three approved capstones ships with a design document, a build log and recorded evidence of its checks, along with a plain list of what it does not do.

Away from the keyboard, you'll find me with a book, any genre, or playing football.

  • Real problems first

    Booking a doctor, managing a gym, planning a trip. Every project starts from someone's actual need.

  • Whole-system thinking

    React and Next.js interfaces, Express APIs and MongoDB schemas, built as one system with clear boundaries between the parts.

  • Interfaces that feel considered

    Responsive, accessible and quick to load, built with Tailwind and Framer Motion.

  • Dependable by design

    JWT auth, role-based access, idempotent writes, verified webhooks and honest error codes are planned in from the start, not patched on.

Experience

Hands-on work you can verify.

Jul 2026 to Oct 2026

Back-End AI Engineering Intern

FlyRank AI Internship Program · Remote

I worked through 35 practical assignments covering API contracts, task design and prompting, retrieval and grounding, and evaluation and operations.

Three capstones were approved, each with a design document, a build log and recorded evidence of its checks.

At least 221 hours documented, 7 program meetings attended and 20 verified Anthropic Academy courses completed.
