Machine Learning Engineer with 3+ ๐ฒ๐๐๐ซ๐ฌ ๐จ๐ ๐ฉ๐ซ๐ข๐จ๐ซ ๐ฉ๐ซ๐จ๐๐ฎ๐๐ญ๐ข๐จ๐ง ๐๐ฑ๐ฉ๐๐ซ๐ข๐๐ง๐๐ building and deploying ML systems that drive revenue, reduce operational cost, and scale reliably in real-world environments. Prior to my Masterโs, I served as a production AI/ML engineer shipping commercial systems. During my Masterโs at Monash (2024โ2026), I led applied research & commercialisation contracts for University of Melbourne, Monash University, Murdoch University and the University of Warwick (UK)โleveraging high-performance infrastructure (HPC, NVIDIA A100s) to bridge the gap between deep research and industrial production. |

My work focuses on designing end-to-end, production-grade ML pipelinesโfrom data ingestion and training to deployment, cost optimization, and monitoringโspecializing in LLMs, Generative AI, Computer Vision, and OCR.
- Production ML (@ Pencil AI): Scaled generative ad systems for 40+ brands; improved CTR by 25% and reduced CPA by 15%.
- Systems at Scale (@ UniMelb / Monash): Deployed OCR + Agentic AI pipelines processing 1.1M+ documents with 90%+ accuracy.
- Infrastructure & Cost: Optimized latency to <7s on NVIDIA A100 clusters via RAG and selective model quantization.
- Most Innovative Award | Monash ImpactHack 2025: Recognized for technical excellence in architecting novel AI solution at Monash Hackathon.
- Top 1% in Monash Statistical Data Modelling (2025): Ranked at the pinnacle of the Kaggle leaderboard across the entire AI/DS/IT/CyberSec cohort.
- Most Innovative Idea Award | KEYCODE 2023: Awarded for creative technical strategy and execution at KeyValue.
- #1 Product of the Day (ProductHunt, 2023): Led the AI Team and ranked 1st globally at launch; 2K+ upvotes, 1K+ user signups.
- Covid Public Health Infra: Contributed to the CoronaSafe Network, officially integrated into the Kerala Govt. Covid War Room for state-wide pandemic response in 2020.
- Open-Source npm package (2023): Architected a custom Rails Engine and open-sourced npm package (@bigbinary) to standardize push notification delivery across Safari and Chromium, scaling the service to 21+ products and increasing user retention by 15%.
