02 — About

I build the
systems
behind the app.

For two years, I've worked on production systems — designing REST APIs in Node.js and Express, building services with RabbitMQ, and designing schemas in Sequelizefor Postgres and MySQL. The focus is on what matters: webhooks that don't double-charge, settlements that stay accurate, and dashboards that load quickly.

I follow SOLID principles, MVC, and event-driven design — and use AWS Lambda · RDS · API Gateway when serverless makes sense. I've also written ReactJS for the booking and learner screens I built on the backend, plus AngularJS for an admin panel. The goal stays the same: a clean system that works well for the people using it.

Three systems
I've built.

A short list of the production apps I've built at Redblocks — projects where reliability, accuracy, and good code go together.

I.
Service Industry
Backend lead · UI integration

Pumperpal✺

On-demand septic-tank service, dispatched in real time.

  • ·01Designed and implemented a scalable RESTful API in Node.js and Express for the full service-booking loop — customer requests, technician dispatch, scheduling, and live job-status tracking.
  • ·02Integrated a third-party payment gateway with webhook event handling for real-time transaction confirmation, refunds, and reconciliation.
  • ·03Built JWT-based auth and role-based access control for customer, technician, and admin roles, with secure middleware on every protected route.
  • ·04Indexed and tuned MySQL tables to keep high-frequency booking and tracking endpoints fast under load.

CPD Health Network✺

Multi-tenant CPD courses for healthcare professionals.

  • ·01Built a multi-tenant RESTful API platform letting healthcare professionals discover, enrol in, and complete CPD-accredited courses with role-based access for learners, instructors, and admins.
  • ·02Modelled a normalised PostgreSQL schema in Sequelize for course content, profiles, enrolments, and progress milestones.
  • ·03Developed an automated certificate-generation pipeline triggered on completion, with progress-tracking APIs feeding real-time learner analytics.
  • ·04Hardened the surface with input validation, error-handling middleware, and structured logging for production debuggability.

Exsplit✺

Microservices for expense sharing & settlement.

  • ·01Architected a distributed Node.js microservices system with clear service boundaries for users, group expenses, settlements, and notifications.
  • ·02Wired RabbitMQ as the async message broker, delivering real-time balance-update notifications across devices with low latency.
  • ·03Engineered multi-party settlement algorithms supporting equal, percentage-based, and custom splits — with transaction-safe writes under concurrency.
  • ·04Cached session and group data in Redis, cutting redundant DB calls and lifting overall system throughput.
  • ·05Built the AngularJS admin panel for user management, transaction oversight, and settlement monitoring.
