🖼️ Serverless Image Processor

AWS · GitHub Actions · Terraform

Event-driven pipeline decoupling ingestion from compute via SQS.

• ⚡ 350+ req/sec sustained, 20ms p50 / 110ms p99
• 🔁 Recovered 100/100 jobs from injected SIGKILL crashes, zero stuck/duplicate completions
• 🔒 Blocked a verified zombie-worker race with a DynamoDB fencing token

🗳️ Raft-KV

Go

A from-scratch Raft consensus implementation with a linearizable KV store.

• ✅ 107k+ commands validated across 6k chaos iterations, zero safety violations
• ⏱️ 556ms median / 814ms p99 leader failover across 100 live kills (5-node cluster)
• 📖 7.6k reads/sec at 1.0ms latency via ReadIndex, bypassing Raft log disk commits

🧠 Mini-vLLM

Python · PyTorch · torch.compile

LLM inference engine implementing PagedAttention and continuous batching.

• 🎯 Reaches ~20% of vLLM's throughput
• 📈 10.8x concurrency-32 throughput boost (106 → 1,143 tok/s)
• 🔌 OpenAI-compatible REST API for drop-in client integration

⚡ OCR Fixture Code Detector

Python · PyMuPDF · React · Document AI

Automates manual fixture-code review from electrical plans.

• 🎯 88% detection accuracy across 23 real-world electrical plans
• 🔍 Custom regex over raw OCR tokens to isolate true fixture codes from circuit numbers
• 🖱️ Interactive bounding-box canvas with CSV export
