Shubham Kumar

Software Development Engineer at Polyteia

Full-stack and DevOps engineer. I ship Go and TypeScript backends, Next.js frontends and the Kubernetes infra underneath them, I also like talk about what I learned on Instagram.

At Polyteia I do DevOps side (Terraform, Helm, CI/CD across dev, sandbox and production clusters) backend and sometime frontend, I redesigned the SaaS platform on Next.js and Go, moved legacy services from gRPC to JSON-RPC then to oRPC.

Before that I built fintech frontends with Stripe, conversational AI on Dialogflow CX and Gemini, and computer-vision models for PCB defect detection.
