Trading Engineer · Flow Traders, Hong Kong
C++17/20 HFT · Lock-free systems · Exchange connectivity · Sub-millisecond latency

What I do

I build and maintain co-located, low-latency trading infrastructure at Flow Traders — exchange connectivity, market-data feed handlers, and event-driven middleware for digital-assets strategies operating at sub-millisecond latency.

Previously: quant engineering intern at Triapti Research (C++ tick ingestion, Kafka pipelines), open-source contributor to Google DeepMind tooling, and internship at Telus International (Node.js microservices on Kubernetes).

Core stack

Domain Technologies
Systems / HFT C++17/20, lock-free queues, feed handler architecture, co-located Linux
Streaming Apache Kafka, multithreaded pipelines, real-time risk monitoring
Infra & DevOps Docker, Kubernetes, Helm, ArgoCD, Jenkins, GitHub Actions
Observability Prometheus, Grafana, latency profiling, structured logging
Algorithms Graph theory, dynamic programming, probabilistic optimization, ICPC
Other Python, SQL, Bash

Featured projects

market-data-aggregator — C++17

1M+ ticks/sec ingestion pipeline with lock-free SPSC queues, CRC32 validation, sub-10ms p99 latency, Google Test suite, Docker/CI.

Key design: cache-line aligned Tick struct (64 bytes), compile-time CRC32 LUT, per-feed latency histogram, feed state machine (CONNECTING → ACTIVE → STALE → DROPPED → RECOVERING).

Probabilistic-Optimization-of-MSTs — C++

Cut & Cycle Model 2-approximation for MST under edge uncertainty. 35% fewer edge queries vs baseline. Benchmarked over 500+ randomized test cases.

VISION_AI — Published research

AI-assisted navigation for visually impaired users. Obstacle detection + depth estimation via Google Gemini. 94% satisfaction across 15 pilot users. Published in IJCSPUB Vol. 14, Issue 2, 2024.

Competitive programming & awards

  • 🥇 Global Rank #47 — Google Solution Challenge (2024)
  • 🏆 Rank #1 — TechX Nova Global Hackathon (5,000+ participants)
  • 🎯 Top 5% — Adobe Gen-Solve Hackathon
  • 🔢 ICPC — Amritapuri Regional Qualifier
  • 🎓 Full merit scholarship, NIT Jalandhar (Top 5% cohort)
