Subhajit Sarkar.
Building AI-powered SaaS tools, full-stack web applications, and intelligent systems from Goalpara, Assam — integrating Grok AI, Google Gemini, and computer vision into real-world products.
Who I Am
I'm Subhajit — a self-taught developer and aspiring penetration tester from Goalpara, Assam, India. I dropped out of my CSE Diploma at the 4th semester to go all-in on building real products that solve real problems.
My stack centers around Python, Flask, and MongoDB, integrated with cutting-edge AI APIs — Grok AI, Google Gemini, OpenAI GPT, and DeepFace. I've shipped face-recognition attendance systems, AI assistants capable of running OS-level commands, and full-stack B2B websites for clients across Northeast India.
On the side I practice ethical hacking through CTF challenges, research bug bounty programs, and apply OWASP security principles in everything I build. I'm also a published fiction author — my debut book The Boy, The Bird, and The Sky is available on Amazon KDP.

What I Know
What I've Built
An AI-powered chatbot inspired by the Bhagavad Gita — intelligent guidance with a custom philosophical persona, cinematic UI, persistent chat history, and full-stack Flask + MongoDB architecture live on Render.
Local system guardian with deep OS integration — runs shell commands, manages processes, monitors WiFi and system health, all via browser. v6 ships process kill from UI, chat export, persistent API key storage, mood detection engine that adapts tone dynamically, and 15 security bugs fixed from a full audit (including unauthenticated command execution).
End-to-end digital transformation for a computer education franchise — custom website, automated receipt generator (Flask web app), official document management system, and proposal portal. Solo-built from design to deployment across four separate repos.
Enterprise on-demand solution: DeepFace VGG-Face recognition for student and staff attendance, CCTV object tracking, JWT auth, Twilio SMS alerts, and automated PDF/Excel report generation. Multi-tenant school ecosystem.
A full e-commerce platform built from scratch — product listings, cart management, order processing, and admin dashboard. Custom-built without any framework templates, demonstrating end-to-end full-stack commerce architecture.
Upload a photo, get your perfect eyeglass frame shape — powered by Google Gemini's vision API analyzing facial geometry (oval, square, round, heart). Instant, personalized optical recommendations without manual measurement.
An open-source romantic surprise website builder — a special way for partners to express love digitally. Fully customizable, deployed instantly. Open-sourced to help lovers who want something more personal than a text message.
Production-ready website prototypes for educational institutions in Northeast India — Alloy Academy Goalpara and an English school. Features admissions, faculty listings, events, and CBSE compliance pages. Part of a broader B2B push across Assam.
An ambitious strategic life-planning engine — maps every possible outcome across a 10–50 year horizon from a set of user decisions and variables. Multi-path future modeling at a systems level with AI-assisted probability weighting.
How I Can Help

What I've Earned
Words I've Written
A debut work of short literary fiction — quiet, reflective, and human. The story of a boy, a bird, and the vastness between them. Published independently via Amazon KDP, proving that a developer's mind can hold both logic and longing.
View on Amazon ↗A developer blog where I write about Python, AI integrations, Flask architecture, cybersecurity experiments, and lessons learned building real-world projects from Northeast India. Honest, practical, and from the trenches.
