About

I build AI that actually ships. At Epsilon, I designed and deployed a production RAG system using Amazon Bedrock, not as a side project, but as a live tool used by 150+ employees daily. Before that, I was at Pixis building ML pipelines and integrating GPT-4 into automated workflows that cut manual processing from 45 minutes to 5. That's the kind of work I'm drawn to: taking a messy real-world problem and building something intelligent around it. My background sits at the intersection of data engineering and data science. I've spent time in the full lifecycle — cleaning and pipelines on one end, model building and GenAI on the other. I work across ML, deep learning, NLP, and reinforcement learning, and I've published research in IEEE and Elsevier on topics from brain tumor detection to explainable AI. Outside of work, I'm building a dynamic pricing engine using reinforcement learning, fine-tuning a domain-specific LLM, and completing my Databricks Data Analyst certification. I'm constantly exploring — hiking, pottery, painting, running, and keeping a newsletter where I write about what I'm learning. I lead community initiatives at Epsilon. I like doing a lot of things, and I think that curiosity shows up in how I approach problems. What I'm looking for: a Data Scientist, AI/ML Engineer, or GenAI Engineer role where I can own problems end-to-end — from raw data to something that runs in production and actually moves a metric.

Associate Software Engineer (Data Engineer)

Aug 2024 – Present · 1 yr 10 mos · Hybrid

Designed and deployed a production GenAI RAG application end-to-end — from architecture to live deployment — using Amazon Bedrock, Claude 3.1, and Titan embeddings, solving a real business problem of unstructured data inaccessibility for 150+ employees. Owned the full LLM evaluation loop: iteratively refined prompt templates and retrieval logic to measurably reduce hallucinations and improve answer relevance in production.
Built and optimised large-scale ETL pipelines on Databricks (PySpark, SQL, Delta Lake) processing 100K+ daily transactions — applied query partitioning and algorithmic optimisations that reduced pipeline latency by 35%, directly improving data reliability for downstream ML and analytics teams.
Integrated Python and shell-based anomaly detection and data quality monitoring into production workflows, cutting downstream analytical issues by 60% and improving the accuracy of business decision-making at scale.
Conducted ad-hoc analysis and presented findings to cross-functional stakeholders across Dev, QA, and BA teams — delivered insights that reduced operational dependency on the data engineering team by 40%.
