🧠 My Ideology

I enjoy solving problems where reliability, scalability, and system design matter more than frameworks.
I'm always interested in understanding not just how systems work, but why they fail.

🔥 Things I've Shipped

Project What makes it real
⚙️ LeetCAD — Event-Driven Microservices Assessment Engine Architected an event-driven engine (3 microservices) in a Turborepo monorepo · Transactional Outbox for atomic dual-writes · Claim-Check pattern for 5MB+ file uploads via presigned MinIO URLs · sandboxed OpenCASCADE geometry worker with DLQ recovery · Redis fencing tokens + Socket.io cross-instance broadcasts
🔐 Quantum Safe Messenger — Zero-Knowledge Relay Infrastructure Stateless relay, 7 REST + 4 WebSocket endpoints, routes opaque ciphertext only — zero plaintext, keys, or PII server-side · Redis TTL offline queuing cut infra cost ~60% vs Kafka/RabbitMQ · Silent FCM push pipeline leaks nothing · SHA-256 fingerprint identity, no OAuth/phone auth · ~50MB Alpine Docker image, live on Google Play Store
