How I built a self-healing, triple-verified financial system for Tixin.in — an event-ticketing platform.

How I hosted a production-grade stack on two Raspberry Pi 5s with k3s — ~1000 concurrent connections and 16k req/sec during load testing.

Designing a high-throughput event pipeline using Kafka + CQRS to process 1.8M records in under 10 minutes.

Built a local auto-scaling load balancer that spins instances, health-checks, and routes traffic based on load — shipped in ~4 hours.

A full-stack decentralized betting dApp on Solana. Smart contract in Rust + Anchor, frontend in Next.js.

Built MyMQ: a Redis-inspired message queue in TypeScript, and a Redis-compatible key-value store in Go to learn systems programming and concurrency.

A production-ready, event-driven banking platform with Kafka, Saga pattern, RBAC, and 95%+ test coverage.

Notes & best practices for combining monorepo tooling like Turborepo with microservices — faster builds, shared packages, and scoped commands.

A 4-hour build: a tiny React-like library with hooks, VDOM, and a custom renderer — for learning how frameworks actually work.

AI-backed learning platform with emotion-aware feedback, flashcards, community features, and RAG-backed assistants.
