Building platform + GenAI systems • Open to backend/platform/AI engineering roles

Vikash Kumar

Senior Full Stack & AI Platform Developer (Infosys) — API gateways (Kong/Akana/Apigee), Kubernetes/DevSecOps, and LLM-enabled automation.

I design and build secure, scalable backend and platform systems across telecom and financial domains — from microservices and API governance to Kubernetes operations and automation. Recently, I’m focused on GenAI integration (RAG, prompt engineering, fine-tuning workflows) and developer-platform engineering.

Engineering Philosophy

How I conceptualize, build, and scale production-grade systems.

01
API-firstThreat modelSLOs

Design

Start with the contract, the guardrails, and the service level objectives. I focus on defining clear boundaries and failure modes before writing a single line of code.

  • Define APIs and auth boundaries early.
  • Select gateway patterns for governance.
  • Design for operability and metrics.
02
FastAPIMicroservicesDX

Build

Shipping small, reliable services with strong defaults. I prioritize simplicity and correctness to ensure long-term maintainability and performance.

  • Production-ready microservices.
  • Automated scaffolding for speed.
  • Clean interfaces and versioning.
03
DevSecOpsPoliciesSecrets

Secure

Making security automated and invisible. I embed security controls directly into CI/CD pipelines to enforce policies without slowing down delivery.

  • Embed controls into CI/CD workflows.
  • Enforce least privilege access.
  • Automated policy enforcement.
04
KubernetesGitOpsObservability

Scale

Running workloads on Kubernetes with GitOps patterns. I focus on traffic governance and reliable multi-environment delivery.

  • GitOps-driven delivery (ArgoCD).
  • Robust traffic governance.
  • Observability-first operations.
05
RAGAgentsFine-tuning

Intelligence

Integrating LLM workflows into platform engineering. I make AI observable, safe, and truly useful in real-world production systems.

  • LLM workflow integration.
  • Observable and safe AI systems.
  • Data-driven fine-tuning.
