Greatman

Mechanical Engineering student at AFIT Kaduna, freelance software developer. I build things across web, mobile, and low-level systems — self-taught in Flutter, Dart, C, C++, Python, and Node.js.

What I'm building

Corridor — a campus platform (not tied to any one school) with a live feed, DMs with realtime, course ratings, push notifications, and Google OAuth. React/Vite + Capacitor on Supabase, live on web and Android at aisle.godpikin2009.workers.dev. Ran a full security audit on the backend and patched confirmed RLS vulnerabilities before launch.

Gamearn — a gaming platform built for a client, Flutter frontend translated directly from Figma via the Figma MCP workflow, backend in Node.js and FastAPI. Game engines (Ludo, Ayo, Whot, Draughts) written in C++ with OpenSpiel, wired to a bot service. Handles wallets, tournaments, and multiplayer.

SendTalk — offline mesh messaging with a C core as the source of truth and a Flutter shell over FFI. X25519/Ed25519 encryption via Monocypher, store-and-forward routing over WiFi Direct, and a symmetric ratchet for forward secrecy. Long-term goal: a mesh-first Android device with a LoRa co-processor.

Oscar — a personal AI assistant running fully on Cloudflare's stack (Workers, Vectorize, Workers AI, D1, KV, Durable Objects) at zero cost.

Background

200-level Mechanical Engineering, first semester CGPA 4.95. I like connecting what I study to what I build — recently ran an informal vibration analysis on a standing fan to test resonance theory from my Mechanical Vibrations coursework against something physical.

Interests

Cryptography, mesh networking, hardware-adjacent software, and anywhere mechanical systems meet software.
