I am Tawhid. I like the parts of software people skip.
Deployments, tests, audit logs, supply-chain checks. I am a final-year CSE student at BUET in Dhaka. I write React, Python and C++ across web, mobile and backend, and I care about what happens after the code is written.
Part-time now, 5 to 7 hours a week.
10 to 15 hours a week from December.
Overlaps easily with India, Europe and Australia.
Permissions and budgets for AI agents. Each agent and sub-agent carries a capability token with a spend and call limit, and every action lands in a hash-chained ledger.
What I did: the release pipeline with signed images and an SBOM attestation, k3s manifests checked on a live cluster, container hardening after Trivy findings, the console UI and demo scripts, and the threat model.
Data over a phone call when the internet is down. Short payloads, like GPS coordinates or emergency codes, travel as sound over ordinary 2G voice calls.
What I did: the C++ plugin core for Jami: FSK modulation, framing, forward error correction and the media handler.
A supplier catalogue platform for XIndex Group of companies. Create a company, add and search items, and view company details from any item. Upload a PDF catalogue and the items fill themselves in.
What I did: the platform itself, with OCR and the Gemini API reading the catalogues.
An enterprise procurement platform, shown at a capstone design fair.
What I did: CI/CD, the system architecture, and the hash-chained audit log, including an admin panel that verifies the log on demand.
Part-time
Core developer on DataGhurhi, a large, externally funded BUET CSE platform for survey creation and data analysis, in a 9-member team. I built the survey part, used by 200+ people (React, Node.js and Django backends, PostgreSQL), deploy it on a university VM with Nginx and PM2, and wrote its end-to-end tests with Playwright.
Part-time
Built the React Native app for Android and iOS with local SQLite storage: the main skeleton and first UI, the compass (it works from the phone sensors), the prayer tracker and the analytics.
Part-time
Research and development projects led by Prof. A. B. M. Alim Al Islam, including software development and mental-health research.
Part-time
Built the React frontend of a water-level tracking dashboard for internal use at WARPO, a Bangladesh Water Development Board project.
On the side: a semantic analysis of user reviews of salah apps, prepared for a CHI paper, and a compiler for a subset of C, built with ANTLR for a CSE course.
