Duration: [October 2024 - Present]
• Tech Stack: Python, Go, Ruby on Rails, AWS, Postgres, Redis, Docker, Kubernetes, Shell Scripting, Git, CI/CD
• Delivered Futures platform performance validation at 3x production load, sustaining 99.99% uptime and 0% downtime attributable to performance, scaling, or endurance issues.
• Designed and built v1 of a Retail Bot mimicking real-world user behaviour across all critical trading flows, with plug-and-play control over user count, RPS, and API composition.
• Shipped ByBit Futures and Options WebSocket integration in Go, extending platform exchange connectivity and enabling derivatives trading across new markets.
• Cut liquidation completion time by 63% (167s to 62s) and open-order cancellation latency by 97% (132.8s to 3.6s) through systematic load profiling and defect resolution.
• Engineered an automated RDS monitoring system that reduced AWS costs by 71% by detecting and flagging idle clusters twice daily via Slack.
• Designed centralised Datadog dashboards consolidating API and WebSocket latency metrics, cutting manual monitoring effort from hours to minutes.
• Delivered a data-backed 2.3x infrastructure cost reduction for Futures DB I/O optimizations with formal sign-off and confirmed zero performance regression.
• Conducted 25+ technical interviews for senior engineering roles, contributing directly to team growth and maintaining hiring standards across the engineering function.
• Mentored 3 junior engineers and authored Confluence Documentations now used as the team standard for onboarding.

Role: Software Engineer (SDE-I)
Duration: [July 2023 - September 2024]
• Tech Stack: Python, REST API, gRPC, Websockets, AWS, Kafka, Kubernetes, Datadog, Grafana, Jenkins
• Delivered Spot and Futures performance validation at 5x production load (12,000 req/sec), sustaining 99.99% uptime and 0% downtime from performance, scaling, or endurance issues, resolving all critical bottlenecks ahead of production release.
• Reduced critical API latency by 96% (p99 from 3,900ms to 150ms) and Verify Token response time by 85% through query optimisation and caching.
• Built a WebSocket sanity validation framework that reduced manual testing from 60 minutes to under 5 minutes via a single Jenkins pipeline
• Brought Portfolio gRPC latency from a 60s timeout down to 230ms at p99, with p50 dropping from 27ms to 9ms under 10x load through iterative profiling.
• Delivered Cross Margin Trigger Service performance sign-off with 80% latency reduction (150ms to sub-30ms), validated stable at 10K users and 53K positions.
• Validated that ElasticCache delivered 7-8% lower socket latency than RedisLabs across 165,000 persistent connections, directly influencing the infrastructure migration decision.
