Full-stack engineer, 4+ years, 20+ products shipped end to end. I build products from idea to production and then stay with them — the interface people use, the AI features behind it, and the infrastructure that keeps both running. Also the software behind physical devices: RFID attendance terminals, ESP32 exam-hall displays, pharmaceutical calibration machines, offline-first POS.
Currently a Software Engineer at WebBoxes, shipping with TypeScript, Next.js, NestJS, Postgres — and whatever the problem needs. I publish and maintain open-source tooling, and send fixes upstream to the libraries it runs on.

Learning management and exam-prep platform — expert-led courses, real practice exams, a question bank, an AI assistant, and mentor support, localized in English and Bengali. Sole engineer, own product: built and own the full deployment pipeline. Multi-tenant architecture — one deployment serving multiple institutions.

Secure peer-to-peer video conferencing — real-time encrypted video and audio calls for up to 100 participants over WebRTC, with custom Socket.IO signaling and a NestJS backend. No downloads, no sign-ups.

Community volunteering SaaS — "Your Impact, Rewarded." Matches volunteers with organizations and people who need help, and rewards impact through a brand coupon marketplace. Built on a strict server-first architecture with row-level security throughout, an admin approval gate layered across schema, server actions, and RLS policies, and a staging → production promotion workflow behind CI gates.

Calibration and monitoring tool for Gazepack machines used by Renata, one of Bangladesh's leading pharmaceutical companies — automation, accuracy, and easy monitoring for day-to-day factory operations, delivered as web and desktop applications.

Comprehensive event management platform and organizer app, built from a raw idea to full MVP. Led design, development, DevOps, and launch — scaled to 100K+ users within 2 months.

Cross-platform point-of-sale system for restaurants and retailers with live table tracking and seamless offline–online data sync. Solely led architecture and development.
Agentic services built rules-first: the decision itself is deterministic, the model is only allowed to write the language around it, a safety veto sits over both, and nothing returns until it validates against a schema. QueueStorm, the fintech support copilot built on it, reasons over the transaction evidence it is handed rather than over what the model happens to recall.
Django REST API serving two classes of embedded device across a university department: RFID card-punch terminals that record attendance, and ESP32-driven dot-matrix displays showing synchronized time and notices in exam halls. Terminals buffer punches locally through network loss; the server reconciles duplicate and missed reads into per-course attendance and faculty reports. Display firmware by the department; backend and device API mine.
University management system covering admissions, enrollment, attendance, grades, transcripts, fees, library and hostel, with separate operating panels for each office — registrar, exam controller, finance, admissions — and a superadmin panel for university IT. Multi-tenant by design, one deployment per institution.
Bengali-first social platform for blood donation across Bangladesh — donors searchable across organizations by blood type and area, phone numbers private until they agree.
Browser-based dashboard for TV broadcasters to monitor 10+ live news streams simultaneously with real-time, low-latency updates.
Location-based eCommerce rental platform with an interactive party planner tool.
Two real-estate marketing sites — property catalogues with filtering across price, type and location.
Plus client and internal builds not listed here — e-commerce, exam systems, real-estate platforms, marketing sites. The rest is on GitHub.
Merged into Lexical (23k★), Meta's editor framework — Word lists now paste with real numbering and nesting intact, net −94 lines after removing two duplicate implementations elsewhere in the repo.
Merged into tiptap (38k★): the image extension's resizable view was staying hidden on cached images.

Zero-dependency library that cleans Word's clipboard HTML on paste — keeps equations editable as LaTeX, rebuilds fake lists as real ones. Listed in Tiptap's official community extensions.
Brno, Czech Republic (Remote)
Scope requirements directly with clients, then deliver end to end — architecture, backend, frontend, full DevOps pipeline (Docker, CI gates, AWS, monitoring), and backups. Current work: All0e (WebRTC video) in production, plus GoodStanding built server-first on Postgres row-level security.
Dhaka, Bangladesh
First engineer. Shipped four products end to end — Eventspark, a cross-platform POS, a pharmaceutical calibration tool for Renata, and a newsroom dashboard for a national TV network — writing the PRDs and SRS documents with clients and then building against them.
Brno, Czech Republic (Remote)
Built full-stack systems with React, Next.js, Express, and Strapi across multiple client projects; scaled backend APIs with NestJS, PostgreSQL, and GraphQL.
Dhaka, Bangladesh
Rebuilt the UI of the Bengali-language software education platform Poridhi.io with React, TypeScript, and Tailwind CSS.
