> Experience

Cashfree Payments

Software Development Engineer II · Bangalore, India
  • Built an agent that helps merchants author risk rules for fraud prevention. Completed end-to-end development, evals and deployment single-handedly.
  • Implemented Cashfree’s agentic code-review system that runs for pull requests and locally in Claude Code, reviewing 20–30 PRs per week and slowly ramping up.
  • Solely designed and delivered the Chargeback Protection Plan subsystem, spanning merchant onboarding, eligibility evaluation, limit management, and dispute tracking.
  • Owned validation and aggregation for a real-time rule engine, keeping rule-evaluation latency at 50ms p90. Migrated legacy rule filters to the new architecture and built historical backtesting for block-impact and dispute-loss analysis.
  • Developed payment-risk analytics APIs and a streaming transaction-enrichment pipeline processing 250 transactions/sec for dispute sources, dispute-to-sales ratio, and topline risk metrics.

Baton Systems

Software Engineer II · Remote
  • Designed and built a Java and Spring Boot configuration service that delivered on-demand configuration and change notifications to dependent services.
  • Implemented fine-grained role-based access control with JWT, Spring Security, and platform-wide authorization policies.
  • Built event-driven Apache Camel workflows for asynchronous FX-settlement processing and extended settlement logic to support new trade-scheduling controls.
  • Developed configurable approval workflows for transaction processing and rule changes; enhanced cash-flow suppression, manual force-matching, and settlement execution.

Accenture

Software Engineer · Bangalore, India
  • Developed Node.js services to ingest, validate, and transform clinical-study data for downstream analytics.
  • Built ETL workflows feeding Snowflake and added automated data-quality checks, fixing pipeline defects that caused ingestion failures.

Subconscious Compute

Intern · Remote
  • Developed Python and FastAPI services for voice-sample extraction from incoming audio streams and customer analysis.
  • Created Grafana monitoring dashboards backed by Cassandra.

AgentForge

  • Built a Kanban application that runs parallel AI coding agents in isolated Git worktrees.
  • Integrated GitHub and Linear issue import, code review, change requests, merging, automatic rebasing, and conflict resolution.
  • Built with Bun, React, TypeScript, and Tailwind CSS.

CodeWiki

  • Built a system that generates and maintains code documentation and a cross-repository knowledge graph from source code and Git history.
  • Implemented a web-based interface to read and run queries against the generated documentation.
  • Implemented an MCP interface to query the knowledge base from coding agents.

Source Radar

  • Built a configurable platform for continuous inspection of code quality, security vulnerabilities, and linter findings across multiple static-analysis tools.
