Concepts

Stack: Go · PostgreSQL + pgvector · Groq (GPT-OSS 120B) · React · Docker

• Built an autonomous PR-review system integrated via CI/CD (GitHub Actions) and GitHub webhooks, orchestrating 3 parallel AI agents (Security, Cost, Architecture) to flag issues pre-merge in 3–8 seconds.
• Built a concurrent Golang backend (goroutine worker pool, HMAC-verified webhooks) with PostgreSQL + pgvector semantic search over architecture rules, so agents check PRs against codified team standards.
• Built a live React dashboard with an SSE-streaming RAG chatbot and an MLOps feedback loop that logs engineer overrides to improve flagging accuracy over time.
• 🔗 Live Dashboard | Backend API

Stack: Spring Boot · Java · Redis · Apache Kafka · PostgreSQL

• Built an in-memory order-matching engine (ConcurrentSkipListMap) with price-time priority and partial fills; covered by 7 tests including a race-condition regression test.
• Implemented volatility-aware rate limiting (Redis Token Bucket) that tightens capacity from 10 to 4 requests when price swings exceed a 3% threshold.
• Built a circuit breaker (3 failures → cooldown → recovery) with trade events streamed via Kafka to PostgreSQL; ~91ms avg latency under concurrent load.

Stack: React · TypeScript · Node.js · CoinGecko API · MongoDB

• Built a full-stack crypto tracker with live CoinGecko API feeds, JWT authentication, and MongoDB-backed watchlists, cutting page load time by 35%.
• Integrated Recharts analytics and AWS S3 storage for real-time portfolio visualization.
• 🔗 Live Application

Stack: Core Java · Supabase · REST API

• Built a console-based expense management system using clean OOP principles and low-level design patterns.
• Integrated real-time data sync with Supabase over REST endpoints, decoupling local state from remote persistence.
