About

Full-Stack Engineer with 3+ years building systems that scale — and, more recently, systems that reason. At Cronlabs, I built an AI microservice for HP's internal supply chain platform, using an agentic workflow on GPT-4o with a custom Tool Registry of 9 functions mapping LLM intent to internal REST APIs — handling everything from End-of-Service-Life lookups to nested SKU relationships. I designed a dual-LLM routing layer where a smaller model handles intent classification and RBAC enforcement, so the system only exposes what each user is authorized to see. I still care deeply about the fundamentals underneath the AI layer: I rebuilt our product search using Redis ZSETs, taking p99 latency from 100ms+ down to under 10ms across 750K+ products, cut S3 report-delivery latency from ~3s to under 400ms with TTL-aligned caching, and decoupled order processing with RabbitMQ to absorb 3× traffic spikes without degradation. I think in layers — application logic, data access, infrastructure, and now, the AI layer on top. Whether it's prompt-to-API routing, query optimization, or async messaging, I care about the why behind every architectural decision. Technical Highlights: AI/LLM: OpenAI API (GPT-4o), Agentic Workflows, LLM Tool Calling, RAG (BM25, RRF), Spring AI Core: Java, Spring Boot, Spring Security, JavaScript, TypeScript, React, RESTful API Design Messaging & Caching: Apache Kafka, RabbitMQ, Redis Data: MySQL, PostgreSQL, MongoDB, SQL Optimization, Indexing Infrastructure: AWS (EC2, S3), GCP, Docker, Jenkins CI/CD Auth & Security: OAuth 2.0, JWT, RBAC Global Rank 2269 / 100,000+ in TCS CodeVita Season 10 . Always building something.

Software Developer at Cron Labs, May 2025 - Present · 1 yr 5 mos, Bengaluru, Karnataka, India · Hybrid, Built an AI microservice for HP's internal supply chain platform, using an agentic workflow on GPT-4o with a custom Tool Registry of 9 functions mapping LLM intent to internal REST APIs, including End-of-Service-Life and nested SKU queries. Architected a Redis-based SKU search engine (ZSET + ZRANGEBYLEX) over 750K+ products, cutting p99 latency by 95% versus MySQL full-text search. Built an SSO layer using OAuth 2.0 + JWT across 3 internal applications, providing a single revocation point and eliminating per-service login friction. Decoupled order processing with RabbitMQ, enabling the system to absorb 3× traffic spikes without degradation.
