An auth-gated admin panel with a schema-driven CRUD engine (Firebase Auth + Firestore) that manages this site's own content — Skills, Projects, and Experience all run through one reusable component, plus a live analytics view and a contact-message inbox. No redeploy needed to edit a word.
Autonomous delivery robot built for an Electronics Lab course — obstacle avoidance and path-following on Arduino.
→ 1 paper, submission-ready for ICCIT
A research paper on reducing the environmental cost of running large language models — submitted for conference review, now being extended into a full paper for journal submission.
→ 200+ publications, structured JSON output
Manually hunting down the right IEEE template for each publication wastes real time. Built a Python + Selenium crawler that drives IEEE's official template selector across 200+ publications, with retry logic for flaky loads and structured JSON output per template.
→ direct device-to-device, resumable transfers
Sharing files between nearby devices usually means routing through the cloud. Built a Flutter app using mDNS for automatic peer discovery (QR fallback), HTTP range requests so interrupted transfers resume instead of restarting, and SHA-256 verification with automatic retry on corrupted chunks.
→ daily-use replacement, zero ads
My phone's physical volume button stopped working, and the existing AssistiveTouch apps I tried showed ads and lost their permissions after a few hours. Built a scoped-down replacement: a floating on-screen control, no ads, stable permission handling.
→ 3 official letter formats, reusable class
Producing a properly formatted official Bangladeshi letter usually means re-fighting layout in Word every time. Built a LaTeX document class that handles mixed Bangla/English text, bundled fonts, and ready-made templates for school, bank, and government letter formats.
A Chrome extension that shows where you left off on every project — community, academic, and personal — in one glance: tracks projects with category tags, parses markdown notes (paste/upload/connected local file), surfaces automatic "checkpoint" summaries, and shows progress bars with staleness indicators (fresh/aging/stale) via a toolbar badge and side panel.
