Hi, I'm Delwer.
I build systems that ship.

Full-stack developer & AI integration engineer. I build marketplaces, e-commerce, POS systems, and AI-powered tools — end to end, from database schema to deploy. 6+ years across development and corporate IT.

Working system

The toolbox I reach for, chosen because it ships.

A practical stack for product interfaces, business logic, data, AI integrations, and production delivery.

what I do

Build

Next.js + Laravel, schema to deploy: marketplaces, e-commerce, POS, dashboards. Production, not prototypes.

See projects

Automate

6+ years across IT operations, web development, automation, hosting, and infrastructure — internal tools and workflows that save real hours every week.

My experience

AI

OpenAI & Claude integrations: assistants, content pipelines, and agentic workflows wired into real products.

Reach

From Chattogram — building across borders.

I work in English on UK/EU-friendly hours from Bangladesh. CarVendors — a live UK used-car marketplace — I built end to end. Distance has never been the constraint.

AI — how I work & what I ship

AI isn't a buzzword here — it's how I work and what I ship.

  • Claude Code as a daily driver — custom agents & skills for code review, security review, and DB-migration checks.
  • Claude & OpenAI API integrations in client products: assistants, content pipelines, agentic workflows.
  • Decisions cross-validated across Claude, ChatGPT, Gemini, and Copilot — shipped, not just prototyped.

what I can do for you

Web Apps & Marketplaces

Custom apps and stores from scratch with Next.js & Laravel — vendor dashboards, search, payments, auth, admin. No templates.

AI Integration

Claude/OpenAI features in new or existing products: assistants, document pipelines, content workflows, agentic tools.

Business Systems & POS

POS systems, multi-role admin panels, reporting, and the internal tools everybody depends on — documented and handed over.

Automation

Social-posting automation, bot alerts, scrapers & data pipelines — the busywork of a whole corporate group, automated away.

Delivery system

One partner from the first build to the next release.

I stay close to the business problem, own the technical decisions, and carry the work through production.

Start a project
  1. 01

    Build

    Product foundations that can grow without a rewrite.

    Marketplaces, commerce, POS, dashboards, APIs, and the data model behind them.

    Proof: CarVendors / Bodhua Bazar

  2. 02

    Automate

    Less repetitive work inside the daily operation.

    Alerts, scheduled jobs, data pipelines, publishing flows, and internal tools.

    Proof: B&F corporate operations

  3. 03

    Integrate

    New capability without breaking the existing system.

    AI assistants, payments, third-party APIs, authentication, and business tooling.

    Proof: Claude / OpenAI / Stripe

  4. 04

    Ship

    A production release, not a hand-off folder.

    Testing, deployment, DNS, CI workflows, documentation, and a clean handover.

    Proof: Vercel / cPanel / GitHub Actions

  5. 05

    Maintain

    Long-term ownership after the first release.

    Monitoring, fixes, improvements, and practical support as the operation changes.

    Proof: Production systems under active care
