Experience

Where the work has happened.

  1. Viralspot AI

    Ontario, Canada · Remote

    Software EngineerFull-time

    Nov 2025 — Present

    Software design · AWS

    Building the planning tool creators use to find what is going viral in their niche, turn it into a script in their own voice, and get carousels and captions back on brand. Day to day that means the product surfaces, the pipelines feeding them, and the AWS they run on.

    Founder

    Jul 2026 — Present

    Free mock interviews with real people, never AI. Volunteers run structured sessions across 12 career tracks, matched by timezone and language, and send written feedback afterwards. The codebase is open source so the service stays free for good.

Honors & Awards

Things that were won or shipped.

  1. National AI Hackathon · MillionX

    Team Shikkha AI

    January 2026

    First place, Education category

    An AI learning platform for Bangladeshi students in classes 9–12, built on a 4B-parameter model fine-tuned on the NCTB curriculum. A Bangla voice agent runs the whole tutoring conversation over RAG, reachable on an ordinary phone call for students with no data as well as online in the app. Alongside it, a textbook reader with streaming AI chat and a photo-to-solution math solver. Prize: BDT 50,000 and a MacBook Air M4.

  2. Hack The AI · Green University

    Team Merge Conflict

    September 2025

    Fifth place

    HireLens AI, a job board that builds itself. It scrapes the Facebook groups where Bangladeshi dev and CS roles actually get posted, runs each post through AI to pull out role, skills, salary and location as structured data, drops duplicates, and has it listed and searchable within minutes. Plus a stats dashboard, saved filters and hourly digest emails.

  3. DIU Agentic AI Competition

    With Wisdomic AI

    April 2025

    Second runner-up

    The real founder of Wisdomic AI. Research tooling that takes paper analysis, literature review and citation management from hours down to seconds: structured paper breakdowns, citation extraction with APA, MLA and Chicago bibliographies, plagiarism detection, and course and career guidance. Founded it and wrote it from the first commit in February 2025 — the whole thing is now open source, and the history is the record. Two early browser-extension attempts are public alongside it.

  4. Dr. Imran Mahmud, Professor & Head of Software Engineering, DIU

    April 2025

    Sold an extended DIU Academia Review to the university

    The original platform stays under our ownership and remains live. Both versions keep full anonymity for every user.
