Title: Scalable Headless E-commerce API Layer

Explanation: Architected a secure API gateway layer for a headless commerce startup. This custom middleware (deployed on Vercel Edge with Next.js) orchestrates data between the Shopify GraphQL API, Stripe Payments, and a Supabase DB. Optimized a critical database query that reduced product page load times by 40%. The result is a secure, extremely fast checkout experience that handles high traffic spikes without latency, directly impacting customer conversion metrics.

Building reliable backends is what I enjoy most.

I work with Python, FastAPI, PostgreSQL, SQLAlchemy, Docker and REST APIs, building backend systems that are clean, testable and easy to extend.

I can help with: • REST API development • PostgreSQL & database integration • JWT authentication and RBAC • Backend debugging and bug fixing • API integrations and automation • Docker setup and automated testing

I’ve also built projects involving e-commerce workflows, payments, inventory, document processing, analytics, webhooks and workflow automation.

If you’re building a product, improving an existing backend, or need help fixing something that just refuses to work — feel free to reach out.

Available for freelance backend projects.
