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 and commercialisation contracts for major universities (Melbourne, Monash, Murdoch, Warwick), leveraging high-performance infrastructure to bridge the gap between deep research and industrial production. My work focuses on end-to-end, production-grade ML pipelinesโspecializing in MLOps, Generative AI, robust System Design, and complex OCR. |

- Large-Scale OCR Pipelines: Architected multi-stage data extraction pipelines for complex historical documents and reports, reconstructing tabular data using advanced OCR models. Processed terabytes of unstructured data from AWS S3 utilizing parallel processing on GPU clusters.
- MLOps & High Availability: Designed and deployed production web backends and API proxies (FastAPI, PostgreSQL, Redis), implementing Cache-Aside patterns to optimize system latency to <7s for end-users on NVIDIA A100 clusters.
- Production ML (@ Pencil AI): Scaled generative ad systems for 40+ brands; improved CTR by 25% and reduced CPA by 15% through model quantization and targeted infrastructure optimization.
- Most Innovative Award | Monash ImpactHack 2025: Recognized for technical excellence in architecting a 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.
- Open-Source ML Contributions: Actively contribute to high-impact ML packages, implementing optimizations such as GPU-based FAISS and efficient clustering algorithms.
- #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.
- Open-Source npm package (2023): Architected a custom Rails Engine and open-sourced an npm package (@bigbinary) to standardize push notifications across browsers, scaling to 21+ products and increasing user retention by 15%.
