// About me

Engineer by craft,
problem-solver by nature.

I've shipped production software for clinical workflows used by real healthcare teams — and I know the difference between code that works and code that holds up.

I'm a Full-Stack Software Engineer with 3 years of experience across healthcare technology and global e-commerce. My day-to-day is React, TypeScript, Node.js, MongoDB and AWS — building backend systems and frontend experiences that don't fall over when real users hit them.

At Nextech Systems I work on production healthcare applications where slow or broken isn't an option. Before that I built and maintained e-commerce platforms serving millions of users across 100+ international sites. I recently completed an MSc in Advanced Computer Science at the University of Leicester, which pushed me deep into AI, NLP and machine learning on top of my engineering foundations.

What I actually enjoy: picking apart a messy codebase, finding where the performance dies, and fixing it properly. Building APIs other developers find a pleasure to work with. Shipping things that matter to the people using them.

Nextech · Ophthalmology EHR Platform
ReactTypeScriptNode.jsAWS LambdaMongoDBAgile
  • Engineered TypeScript/React clinical charting components that reduced after-hours documentation time for ophthalmologists by an estimated 25%, based on stakeholder feedback during sprint reviews.
  • Optimised Node.js/Express RESTful APIs handling patient scheduling, billing and EHR data — cutting average API response times by 40% through query analysis, indexing and payload restructuring.
  • Designed MongoDB data models for high-volume clinical records, introducing compound indexing that reduced read latency on patient data queries by over 30%.
  • Deployed and maintained production services on AWS Lambda and API Gateway, supporting zero-downtime release cycles across practice-critical workflows serving active clinical users daily.
  • Drove CI/CD pipeline improvements using GitHub Actions, reducing deployment time and enforcing automated test gates that cut regression incidents in production.
  • Partnered with ophthalmology stakeholders to translate domain-specific workflow requirements into intuitive UI features, reducing manual steps in core charting flows.

  • Built and shipped React/Node.js features on a platform serving millions of concurrent global users across 100+ international e-commerce sites.
  • Implemented lazy loading and code splitting across the React component tree, reducing initial page load time by 35% and improving Core Web Vitals scores across all international deployments.
  • Refactored API call patterns and introduced a custom caching layer, reducing redundant server requests by ~60% and improving throughput under peak traffic conditions.
  • Maintained and extended MongoDB-backed services supporting global product catalogues, user accounts and order management — handling tens of millions of records across multiple regions.
  • Delivered features via AWS Lambda/API Gateway with multiple weekly releases and no major production incidents.
  • Contributed to a 20% improvement in release cycle speed through CI/CD automation improvements and stricter code review standards across the team.
