01 — About

Who I Am

I'm an analytical Software & Data Engineer who thrives at the intersection of reliable data infrastructure and scalable cloud systems. Based in London, I bring hands-on experience across financial services and energy sectors — two industries where data integrity isn't optional.

Currently at Unitech Consultancy Services, I'm engineering data quality tooling for a large-scale banking migration — Sainsbury's Bank to NatWest — covering 1.1M customers. I built a YAML-driven wrapper around Great Expectations that lets ~20 engineers write data quality checks without needing Python expertise.

Previously at GlobalLogic India, I migrated 3M+ British Gas customers to a new AWS-based energy platform, architected serverless Lambda pipelines, and slashed deployment times by 80% with Terraform-driven CI/CD.

I hold an MSc in Big Data Science from Queen Mary University of London and three AWS/Terraform certifications. I write Python that other engineers actually want to use — and systems that don't break at 2am.
