Hi, I'm Sebin Mathew πŸ‘‹

I build Chrome extensions, full-stack apps, security tooling, and exam portals. Backend-leaning developer who keeps things private by default: no telemetry, modular design, and cryptographic verification where it matters.

  • πŸŽ“ B.Tech in Computer Science & Engineering, College of Engineering Chengannur (CGPA 8.6)
  • ⚑ Currently working on token optimization pipelines, API gateways, and system telemetry

πŸ› οΈ Tech stack & tooling

Domain Technologies
Languages TypeScript JavaScript Python HTML5 CSS3
Backend & APIs Node.js Express FastAPI REST APIs
Frontend React Tailwind CSS
Databases PostgreSQL SQLite MongoDB
DevOps & CLI Git GitHub Actions Podman pnpm

πŸš€ Featured projects

Chrome extension β€’ JavaScript (MV3) β€’ Privacy-first β€’ 25/25 Tests Passing

Compresses prompts in-browser before they hit the API, cutting token use by 40-65% across ChatGPT, Claude, and Gemini. Runs entirely client-side with pure regex patterns, zero external dependencies, and keeps code blocks intact.

πŸ“– Architecture & technical design

Security dashboard β€’ Next.js 15 β€’ React 19 β€’ TypeScript β€’ Local Ollama AI

Real-time cyber threat monitoring and analysis dashboard. Features streaming terminal logs, automated attack simulation, iptables mitigation commands, and optional local AI threat evaluation via Ollama.

Full-stack event platform β€’ FastAPI β€’ React β€’ Tailwind CSS β€’ Live on GitHub Pages

Decoupled event management platform with Pydantic schema validation, search indexing, and SQLite persistence. Deployed live with responsive dark/light theme and local storage demo fallback.

🌐 Live Demo | πŸ“– System architecture & specs

Full-stack social platform β€’ Express 5 β€’ React 19 β€’ MongoDB β€’ JWT Auth

Community impact tracking platform for volunteers. Features 6 impact tracks, title achievement system, privacy-controlled member directory, rate-limited REST API, and bcrypt authentication.

Language & runtime β€’ Python β€’ Tkinter IDE β€’ Pytest Suite

A satirical programming language and IDE that enforces mindful typing. Throttles execution and triggers dynamic ASCII turtle rage and poetic haiku feedback when you type too fast.

πŸ“– Runtime architecture & state machine

UI component library β€’ C# β€’ .NET β€’ Windows Forms

Modern, lightweight Windows Forms UI component library with sleek components, smooth gradients, and custom animations for desktop applications.
