Signals

Live in Production.

Each signal ties back to a specific, evidenced moment.

Built

7 moments

Systems shipped end-to-end, from schema to deploy.

  • •a claude agent harness, above claude code
  • •Shipped a high-throughput candles API with multi-layer caching
  • •Designed Aegis, a centralized SSO library

Learned

3 moments

New tools and depth picked up on the job.

  • •Studying system design concepts
  • •Practicing Data Structures & Algorithms on LeetCode
  • •Studying Agentic AI systems

Solved

2 moments

Gaps closed - false positives, edge cases, dead ends.

  • •Replaced third-party search API with a custom Go engine
  • •Owned UPI/net-banking collection at 99.99% success

Scaled

1 moment

Taken from prototype to real production volume.

  • •Migrated candle generation to TimescaleDB, cutting CPU 70%+

Operated

1 moment

On-call, incidents, and what happens after launch.

  • •Stopped a runaway replication-lag incident with zero data loss

Kill-Switch Risk Control System

Elixir/OTP system that atomically cancels all pending orders and squares off intraday positions across Equity & F&O on trigger, with a fail-open guard so cache outages never block live trading.

Aegis SSO Library

In-house SSO library adopted across 8 microservices, replacing fragmented per-service auth with centralized Google-OAuth sign-in and near-instant session revocation, later extended to gate VPN access.
