About

🚀 Software Developer | HFT | Full-Stack Enthusiast | Competitive Programmer I’m a passionate Software Engineer with a strong foundation in backend development, low-latency system optimization, and scalable architecture design. Currently at Amazon, I’ve led automation initiatives and latency benchmarking efforts, reducing vendor effort by 50% through AWS Lambda-based ingestion pipelines. Previously at Quadeye, I optimized high-frequency trading (HFT) infrastructure, slashing SHM latency from 1.3μs to 1.1μs and automating cross-exchange trading systems using real-time market data (NIFTY/SENSEX). My projects resulted in a 60+ hour/month efficiency gain through strategic automation. At Scaler and Tranzact, I contributed to feature-rich, test-covered web platforms using Ruby on Rails, Django, React, and Node.js. I’m particularly proud of delivering reusable components, flexible scheduling systems, and improving code coverage significantly. 💻 Tech Stack: Python, C++, Ruby on Rails, Node.js, Django, React, AWS (Lambda, EC2, SNS, SQS), MySQL, MongoDB, Redis 🏆 Achievements: Top 2.3% Knight on LeetCode, ICPC India Prelims Rank 284, 1500+ DSA problems solved 🚀 Let’s connect if you’re into systems engineering, competitive programming, or cloud automation! 📩 Feel free to reach out: rahulpalahwat@gmail.com 🔗 GitHub: github.com/Rahul-Palahwat | LinkedIn: linkedin.com/in/rahul-kumar
