Engineering case studies
Production Systems
Not projects. Systems. Each one is a deep technical breakdown of real problems, real constraints, real tradeoffs, and real outcomes. What was built, why it was built that way, and what failed along the way.
CareerLens Agent Platform
AI-native career intelligence platform using LangGraph multi-agent architecture, GPT-4o, OpenSearch, and reflection loops to deliver personalized, structured career analysis.
AI Product Discovery Engine
Production semantic search for an e-commerce marketplace — natural language queries mapped to relevant product categories using Django, Google Embedding API, and Gemini LLM reranking.
Database Performance Optimization
PostgreSQL indexing strategies that reduced query latency 10–40× across a high-volume Django application — without schema migration or application redesign.
Financial Ledger Infrastructure
Audit-ready double-entry ledger system, invoicing engine, and refund workflows for a financial platform — designed for correctness, traceability, and regulatory compliance.
Document Intelligence Pipeline
Production ETL platform processing thousands of banking documents — PDFs, Word files, image attachments — using asynchronous processing, Celery, and Apache Spark.
