Full Stack Developer(Python, Golang), Freelancer

• Migrated WordPress and CMS-heavy sites to static sites with Netlify CMS, reducing bundle size by 50–80% and improving TTFB by 40–70%.

• Built custom ERP, inventory, and SMB systems using Flask (limited built-in auth, admin, and structure at scale) and Django (heavy for API-frist and async workloads), later transitioning to FastAPI for async APIs and microservices, improving response times by 30–50%.

• ImplementedheadlessandlightweightplatformswithDirectus(richAPIswithhigher resource cost) and PocketBase with Go (Gin) and Svelte, reducing infrastructure footprint by 30–60%.

• Standardized environments with Nix, provisioning AWS via Terraform and managing hosts with nix-morph, reducing deployment and environment drift issues by 70%+.

• Deployed via GitHub Actions and Kubernetes, enabling rolling updates, horizontal scaling, and achieving better uptime. June 2019 – June 2025
