About Me

I am a Senior Full Stack Engineer with 9+ years of experience building cloud-native SaaS platforms across fintech, healthcare, and enterprise products. Currently based in London, UK, I focus on reliable backend systems with Python/Node.js, modern frontend delivery with React and TypeScript, and scalable AWS infrastructure.

Recent work includes integrating OpenAI + LangChain workflows into production, designing high-throughput data pipelines with Spark and Redshift, and optimizing API/database performance for real-time workloads. I also drive engineering quality through CI/CD, strong testing practices, and secure system design.

My work is supported by three AWS certifications: Machine Learning Specialty, Solutions Architect Professional, and Developer Associate. I build systems with security and compliance in mind, including controls aligned to ISO 27001 and HIPAA.

Key Achievements:

  • Led a 6-engineer team and improved feature delivery speed by 2x at Blox
  • Reduced financial calculation runtime by 60% using Polars and optimized parsers
  • Improved API and database performance by 40% through targeted raw SQL optimization
  • Built Spark ingestion pipelines for 100K+ row CSV files and cut processing time by 35%
  • Increased healthcare product retention by 25% using recommendation improvements on AWS Personalize
  • Implemented robust CI/CD and security controls across deployments in regulated domains
