I build production software end to end — React interfaces, Python and Node services, Postgres data models — and the desktop and mobile apps, AI agents and devices that plug into them. Based in Dhaka, shipping for teams in the UK.

1. Full-Stack Developer — Green Compare Ltd

   Jun 2026 – Present
   • Initiated the internal CRM repository, then shipped full-stack features across finance, telesales, renewals, pipeline, client files, dashboards and access control (38 merged pull requests).
   • Built Bookodi’s desktop app (Windows/macOS, with a Print Bridge to kitchen printers) and its Android and iOS apps as sole engineer — the mobile layout audit took 915 layout problems on phones and tablets to none.
   • Built a 24/5 market-scanning trading agent on the owner’s specification: 24 merged pull requests and four releases in its first week, 323 tests, CI on Linux and Windows, order automation interlocked off.
   • Designed an HR inbox agent in which a language model drafts and classifies, while deterministic code enforces every safety rule.
   • Ran QA for Bookodi with a live demo-and-test bot covering 147+ of 158 reachable API endpoints; the QA report listed 96 defects with causes and fixes.
   • Wrote Worksi’s 33-runbook library and ran an end-to-end platform test that fired all 11 incident detectors.
   • Built a zero-dependency, progressively enhanced quote funnel for business-energy leads, with an offline UK postcode-to-street index.
   • Work in Scrum sprints with code review on every pull request and CI gates before merge.
   • Rebuilt the CRM’s role dashboards on a shared 12-column widget kit and added a performance board with drill-downs.
   • Moved book statistics from browser-side summing to one server-side filter definition, covered by tests.
   • Made renewals a query-time derivation so a re-signed meter can never be stuck as a stale renewal.
   • Added a responsive end-to-end sweep covering every route, role, 8 viewports and 2 orientations.

2. Brand Ambassador — Kreb (XEOO)

   2026 – Present
   • Represent Kreb ahead of its launch.

3. Full-Stack Developer Intern — Green Compare Ltd

   May 2026 – Jun 2026
   • Redesigned the Analytics page into five sections with a KPI toolbar and Excel export — the module still ships in the live product.
   • Built reservation views: a 24-hour Gantt table plan, a month calendar and a responsive toolbar for iPad.
   • Added the dashboard’s “reservation turn health” panel and live turnover widgets.
   • Fixed a no-show KPI that always read zero and replaced 43 hard-coded colours with theme tokens.
   • Top committer during the June 2026 rebuild of the dashboard (49 of 125 commits).
   • Promoted to a permanent engineering role in under two months.

• Bookodi Desktop & Print Bridge — Sole engineer — design, build, tests, CI, docs

  Native desktop app for the Bookodi restaurant platform with a built-in Print Bridge: it pairs with the cloud in one click, discovers printers on the local network and delivers server-rendered tickets over raw TCP, IPP, LPD, CUPS or the Windows spooler.

  Electron, TypeScript, Node.js, WebSockets, Printing protocols, Vitest, Playwright, GitHub Actions, Vite

• Bookodi Mobile — Android & iOS Apps — Sole engineer — shells, page layer, layout audit, tests, CI, docs

  A Capacitor 8 shell that runs the live Bookodi dashboard inside native Android and iOS apps, with a page layer injected before the web app loads and a mobile layout layer. A layout audit across 123 page states found 915 problems on the website and none in the app.

  Capacitor, TypeScript, Java, Swift, HTML & CSS, Vite, Vitest, Playwright, GitHub Actions, Docker & Compose

• Bookodi — Restaurant Operating System — Frontend & data-visualisation engineer (contributor)

  Bookodi handles reservations, POS, kitchen display, menus, guest CRM, delivery, printing and billing for many restaurants from one Go API. Built by the XEOO team; I owned the analytics module, the reservation views and the dashboard home.

  React, TypeScript, Tailwind CSS, Vite, Go, PostgreSQL, Redis, MinIO / S3, WebSockets, Docker & Compose, GitHub Actions, PWA & service workers

• Green Compare CRM — Project initiator, then full-stack feature developer

  A FastAPI modular monolith with a React 19 front end, where Postgres row-level security backs every permission check. I started the repository, then shipped features across finance, telesales, renewals, dashboards and access control.

  Python, FastAPI, SQLAlchemy, PostgreSQL, Alembic, Redis, React, TypeScript, Ant Design, TanStack Query, pytest, Playwright, Docker & Compose, GitHub Actions, MinIO / S3

• HR Inbox Agent — Designer & engineer

  A Python agent that reads an HR mailbox through Microsoft Graph, asks a language model for a structured classification and draft reply, and lets deterministic code decide whether to send, save a draft or escalate to Slack.

  Python, LLM APIs, Agent guardrails & evals, AI gateways, SQLite, pytest, Docker & Compose

• Market-Scanning Trading Agent — Sole engineer — built on the owner’s specification and prototype

  A Python agent that scans 5-minute candles on gold and two US indices, posts each trade idea with a chart to a Telegram review group and follows every outcome. Built on the owner’s specification and prototype: 24 merged pull requests and four releases in its first week, with the suite growing from 90 to 323 test functions.

  Python, pandas & NumPy, SQLite, Telegram Bot API, MetaTrader 5, pytest, GitHub Actions, Linux, LLM APIs

• Physics-Guided ML for Fabric GSM — Co-author (2nd of 6), presenting author

  Research paper accepted at IEEE ICACT 2026. On 5,648 production samples, an Extra Trees model reached a test RMSE of 4.10 g/m² (R² 0.952, MAPE under 0.5%) after adding a physics-derived tightness factor; SHAP and LIME confirmed the model learned textile physics.
