Systemic is an open-source, AI-powered competitive developer leaderboard that unifies activity from GitHub, LeetCode, Codeforces, and HackerRank into a single XP system.
A collection of work I've shipped — from production web apps to experimental side projects.
This is a high-performance C++20 distributed cache designed to overcome the concurrency and eviction limitations of Redis and Memcached. It features a striped locking architecture for fine-grained reader-writer access, built-in request coalescing to prevent cache stampedes, and a sophisticated LFU-based three-phase eviction strategy. Capable of 3.66M ops/sec with sub-microsecond p99 latency, it leverages modern C++ features like shared_mutex and shared_future to deliver zero-cost abstractions and deterministic performance.
An AI-powered adaptive learning platform built specifically for students with ADHD and dyslexia, featuring dynamic quiz difficulty adjustment, AI text simplification via Groq, dyslexia-friendly fonts and color overlays, and accessibility-first UX.
A Gomoku (Five-in-a-Row) AI on an infinite sparse board, featuring minimax with alpha-beta pruning, tactical move ordering, and a pattern-based heuristic evaluator with a full pytest test suite.
A real-time collaborative text editor built with a Rust-powered OT-core, PostgreSQL persistence, Redis pub/sub, and RabbitMQ message bus — enabling conflict-free concurrent editing across distributed clients.
A real-time conversational AI that lives in Discord voice channels with a full STT→LLM→TTS voice pipeline bridging Discord and LiveKit.
