Startups lose thousands of dollars a day to slow APIs, N+1 database queries, and heavy server timeouts. I fix that.

Building production infrastructure isn't just theory for me. With 7 years of hands-on, self-taught full-stack experience, I specialize in identifying backend bottlenecks and migrating heavy Django architectures to lightning-fast, asynchronous FastAPI.

Through running my own platforms and executing client work, my custom pricing algorithms, Redis caching layers, and AWS CloudFront optimizations have directly supported enterprise-level traffic for brands including Land Rover, Indigo Airlines, and Hilton Hotels.

Core Competencies:

Backend Speed Optimization: Django to FastAPI migrations.

AWS Infrastructure: EC2, S3, Route 53, and Celery worker offloading.

Database Architecture: Resolving N+1 queries and optimizing complex data syncs.

Custom Integrations: Shopify APIs, Webhooks, and Meta CAPI.

If your backend is crashing under load or slowing down your user experience, let's talk. I offer fixed-rate performance sprints to cut your response times in half, without breaking production.
