01 — About

A bit about how I build.

I'm a B.Tech Electronics & Communication Engineering student at IIIT Allahabad (CGPA 8.58), with hands-on experience as an SDE Intern at Aakash Technology Innovation Lab, where I built production microservices on Spring Boot for the Phoenix ERP platform. I care about transaction-safe system design, low-latency data layers, and shipping things that actually run in production — not just demos. Outside of backend engineering, I'm exploring Generative AI: RAG pipelines, agentic workflows, and LLM-backed applications.

JavaSpring BootSpring Security KafkaMySQLAWS S3RedisDocker
  • Spearheaded design and delivery of 20 production REST APIs using a layered Controller–Service–Repository pattern with Spring Security, JWT-based auth, centralized exception handling, and Bean Validation — cutting API error rates by 30% and mean-time-to-resolution by 40% across 5 microservice modules.
  • Overhauled 15+ high-traffic MySQL queries through composite indexing, covering indexes, and execution-plan analysis; introduced JPA projections and batch-fetch strategies to eliminate N+1 patterns — 30% latency reduction and 2x transaction throughput under peak load.
  • Architected backend infrastructure for the Supplementary ID process on the Phoenix platform, reducing end-to-end process complexity by 40% and enabling secure, scalable student onboarding across multi-centre operations.
  • Designed and owned an end-to-end Pricing Engine backed by Redis caching and Spring Cache abstraction, optimizing critical query paths to sub-100ms P99 latency across thousands of course SKUs.
