Backend & GenAI engineer building systems that scale.

Building Java/Spring Boot microservices in production at TCS – SBI YONO 2.0, and independent AI agentic systems with LangGraph

About

Backend Engineer (2 YOE) building Java / Spring Boot microservices in production at TCS – SBI YONO 2.0, supporting 22,000+ savings accounts, with working experience in distributed caching and SQL query optimisation, plus some exposure to Kafka-based event-driven flows. Outside work, I build AI agentic systems (LangGraph, multi-agent pipelines) as independent projects – pairing backend fundamentals with applied LLM and automation engineering, which is the direction I'm looking to grow into.

    System Engineer — Backend Developer

    SBI YONO 2.0, Tata Consultancy Services · Mumbai

    Nov 2024–Present

    • Owned end-to-end delivery of the NRI Digital Journey (NRE/NRO account onboarding) — from solution design through production rollout, supporting 22,000+ savings accounts. Built Java Spring Boot microservices for account creation, KYC validation, and compliance workflows.
    • Improved EDMS document processing (KYC & NRI compliance) throughput via multithreaded parallel validation, feeding into the team's Kafka-based event flow.
    • Improved onboarding throughput 35% using GemFire distributed caching.
    • Built a Spring Batch automation for nightly reconciliation of 100+ failed cases; optimised SQL queries with covering indexes and EXPLAIN-based tuning.
    • Backend point of contact across both NRI journeys, co-authoring solution docs with architects and BAs.
    • Coordinated with DevOps/OpenShift on deployments and CI/CD; participated in code reviews and CMS workflows.
    • Mentored 6 junior engineers on SOLID principles and production debugging — awarded 5-Star Rating twice.
    • Java
    • Spring Boot
    • Kafka
    • GemFire
    • SQL

Projects

  1. 01

    Market Intelligence & Signal System

    2026, In Progress

    • Personal project automating Indian-equities market analysis: Spring Boot jobs ingest NSDL/NSE/BSE + news data; a LangGraph multi-agent pipeline turns it into entry/exit signals and event-impact scores per watchlist instrument.
    • Self-hosted on a Mac Mini (Docker), frontend on Vercel — ingestion, analysis, and presentation as separate layers.
    • Java
    • Spring Boot
    • LangGraph
    • Docker
  2. 02

    Event-Sourced Double-Entry Ledger

    2026

    • CQRS + Event Sourcing core ledger: every balance change is an immutable event, state rebuilt by replaying history for point-in-time balance queries.
    • Enforces double-entry bookkeeping at the domain layer; indexed the event log on account ID + timestamp.
    • Java
    • Spring Boot
    • PostgreSQL
    • CQRS

    Real-Time Collaborative Sync Engine

    2026, In Progress

    • Google Docs-style collaborative editor: CRDT conflict resolution from scratch, WebSocket broadcasting, reconnection, delta-sync after network interruption.
    • Built to compare OT vs CRDT trade-offs at the implementation level.
    • Java
    • Spring Boot
    • WebSocket
    • CRDTs
