About Me

Hi! I’m Yennam Sai Koushik Reddy, an Application Engineer at IDFC FIRST Bank, where I joined as an intern and now work full time. I hold a B.Tech in Computer Science from IIIT Sri City (2022–2026, CGPA 9.2/10). I build backend and full-stack systems with Java, Go, Node.js, React.js, PostgreSQL, Redis, Docker and Kubernetes.

I’m part of my college’s Google Developer Groups as a Backend Developer, where I help organize events and guide others. I also love competing in coding contests: I’m a Specialist on Codeforces (1435), 1857 on LeetCode (top 5.68%) and 3-star on CodeChef (1649).

Beyond backend engineering I enjoy applied AI (selected for Amazon ML Summer School 2025) and API security (interned at Akto.io), and I’m still exploring Machine Learning, Blockchain and Cybersecurity to create exciting projects and grow my skills.

Experience & Education

1. Application Engineer

   IDFC FIRST Bank

   Jul 2026 – Present · Bangalore

   • Built a Copy Deployment feature in the React/Go Config Portal, generating deployment YAML for 300+ microservices across 65+ projects and 11 environments and eliminating manual YAML creation.
   • Implemented a source-to-destination workflow letting developers review, accept or reject deployment values (memory, replicas, topics) before YAML generation, cutting configuration errors.
   • Engineered reusable Go data structures with typed value metadata and integrated React-side YAML processing to preserve structured configurations while supporting environment-specific overrides.

   • Go
   • React
   • YAML

2. Application Engineer Intern

   IDFC FIRST Bank

   Jan 2026 – Jun 2026 · Bangalore

   • Redesigned client onboarding for the Core Banking Config Portal by migrating client configurations from Kubernetes deployment manifests to PostgreSQL, so new clients can be onboarded without infrastructure changes or service redeployments.
   • Built a centralized client authorization module managing Client IDs, Client Secrets, API permissions and endpoint-level access controls (GET/POST/PUT), with Redis-backed caching that cut credential retrieval latency from 9s to under 1s.
   • Delivered a production-style Movie Booking System simulation using React, Go and MongoDB, with movie discovery, seat booking, user management, RBAC and feature-toggle driven releases across DEV, QA and PROD environments.
   • Containerized services with Docker, automated deployments through Jenkins and orchestrated workloads on Kubernetes; contributed to architecture design, database migrations and release management workflows.
