Architected multi-tenant APIs (FastAPI, SQLAlchemy, GraphQL, REST) serving 50+ clients with sub-500ms response times and 99.95% uptime. Built an internal AI assistant using a LangChain RAG stack (vector search) with a React chat UI, integrating cleanly into existing API layers. Led migration from batch ETL to event-driven pipelines (Kafka, Airflow, dbt), reducing data latency from hours to minutes. Managed and mentored a growing engineering team, improved test coverage to 85%+ and increased delivery velocity. Migrated 2M+ records from MySQL to PostgreSQL with zero downtime and query performance improvements. Automated CI/CD with GitHub Actions and Terraform, deploying via Kubernetes/Helm; increased delivery velocity significantly. Drove AI-assisted development adoption and implemented OAuth2/OIDC/JWT with strong security and compliance practices.

Refactored a large Django monolith (1.5M+ LOC) into FastAPI microservices using DDD and CQRS; reduced time-to-market and enabled more frequent deployments. Built high-traffic web applications (React, Next.js, Redux) plus a companion React Native app. Delivered real-time features using WebSockets and async Python with low latency at peak load. Optimized SQL performance and migrated 2M+ records with zero downtime. Led mentorship and increased test coverage while improving CI/CD and development environment setup; implemented Infrastructure as Code on AWS/Azure and reduced cloud costs.

Built financial platform APIs (Django, DRF) for high-volume transaction processing with ACID compliance and 99.95% uptime. Designed numerous REST endpoints with OAuth2/JWT and improved PostgreSQL performance. Built real-time gaming back ends using Python asyncio and WebSockets to support very high concurrent usage and low latency. Delivered SaaS platform functionality with Flask/React/Redux and improved Oracle performance with PL/SQL and CDC strategies. Optimized MySQL leaderboard queries for high record counts, automated reporting workflows with Python tooling, and mentored engineers while supporting reliable CI/CD deployments.
