About

I'm a Full-Stack Engineer with close to 3 years of experience building production applications in Java, Spring Boot, React, Next.js, and TypeScript — and I independently build and deploy GenAI applications using Claude, Gemini, Groq, and Ollama on AWS. At CBREX Technologies, I work on a multi-tenant Applicant Tracking System (ATS) powering a B2B recruitment marketplace. My biggest contribution has been owning the Candidate Portal end-to-end — the platform's first self-serve application-tracking experience for candidates, replacing manual recruiter updates. I designed the relational schema and built JWT-based, role-scoped access control (Spring Security). Some other things I've shipped there: • A precompute-and-cache layer that cut recruiter-facing match-score latency from 20s+ to ~2s, replacing live per-view calls with scheduled Quartz jobs writing to dedicated DB tables. • An automated weekly enterprise reporting pipeline (Quartz-scheduled Excel exports, transactional email, self-serve React dashboards), removing a recurring manual task from client-success. • Backend features extending CBREX's white-label, domain-based ATS architecture, so client companies can run on their own branded subdomain. • Core contributor to two of the platform's largest frontend efforts — a legacy-to-React migration and a candidate-tracking product revamp — including a reusable component library now used platform-wide. • REST APIs and relational data modeling for job-matching and supplier-metrics features, tuning composite indexes and query plans to cut DB load under high-throughput traffic. Outside my day job, I build things end-to-end. My personal project, a Multi-Provider AI Resume & JD Matching Engine, is a full-stack app (Next.js 14, Spring Boot 3, PostgreSQL) plugging into four LLM providers — Claude, Gemini, Groq, and Ollama — behind a common interface, with async processing via Redis queues and an AWS deployment (EC2/S3, least-privilege IAM, no hardcoded credentials). I also built the LLM orchestration behind an internal AI-led interview product, tracing a latency issue to round-trip hop count rather than backend speed and restructuring the real-time flow to fix it. I care about backend systems well-modeled at the data layer, and about understanding AI systems deeply enough to reason about their performance and architecture — not just call an API. Open to Full-Stack, Backend, and AI Application Engineer roles in Bengaluru or remote within India. Always happy to talk Java, Spring Boot, system design, or applied GenAI — feel free to connect.

Work experience

Full-Stack Engineer at CBREX, Nov 2023 - Present · 2 yrs 11 mos, Bengaluru, CBREX is a B2B recruitment marketplace — a global talent-exchange platform built on a multi-tenant Applicant Tracking System (ATS). • Owned the Candidate Portal end-to-end (Next.js/TypeScript + Spring Boot) — the platform's first self-serve application-tracking experience for candidates, replacing manual recruiter updates. Designed the relational schema and built JWT-based, role-scoped access control (Spring Security) for candidates and recruiters. • Cut recruiter-facing match-score fetch latency ~10x (20s+ → ~2s) by designing a precompute-and-cache layer: new DB tables for match scores and salary benchmarks, refreshed via scheduled Quartz jobs against an internal AI-matching microservice — replacing live per-view calls with a direct DB read. • Automated the weekly enterprise client reporting pipeline — Quartz-scheduled Excel exports, transactional email delivery, and self-serve React dashboards — removing a recurring manual task from the client-success team's plate. • Core contributor to the platform's two largest frontend initiatives: a legacy-to-React migration and a candidate-tracking product revamp. Built a reusable component library and shared framework primitives now used platform-wide. • Designed REST APIs and the relational data layer for job-matching and supplier-metrics features (Spring Boot, JPA, native SQL with correlated subqueries and multi-table joins). Tuned composite indexes and analyzed query execution plans to reduce DB load under high-throughput traffic. • Contributed to migrating a new user persona off the platform's legacy Struts monolith into its microservices architecture, building the migrated functionality within existing service boundaries. • Extended CBREX's white-label, domain-based ATS architecture with backend features that let client companies run the platform on their own branded subdomain.
