About
Software engineer combining a mechanical engineering background with professional full-stack experience, most recently building a multi-site SaaS platform for the self-storage industry. I thrive in collaborative agile teams, take ownership of features end to end, and care about writing well tested, maintainable code.
Experience
Full-Stack Software Engineer - ManageSpace
(2024-11 - 2026-06)
- Owned and delivered end-to-end features across a TypeScript codebase built on a hexagonal architecture, working across the full stack from database schema to UI using NestJS, Prisma, MySQL, React, and Remix
- Built and iteratively improved a delinquency system automating overdue payment chasing, unit locking, fee application, and account flagging – evolving the architecture to decouple real-time and scheduled cron processing into a shared code pipeline as complexity grew
- Built a multi-site rate change feature enabling managers to apply and schedule pricing changes across customers and sites simultaneously
- Integrated third-party services including Stripe Identity for KYC verification with full webhook idempotency, and Twilio/SendGrid for automated customer email notifications across core workflows
- Migrated a large portion of the backend codebase from an OOP Prisma/NestJS pattern to a functional programming approach using EffectTS
- Optimised front-end UX across the customer portal, including server-side filtering for improved performance and intuitive customer page navigation
- Developed custom Honeycomb spans throughout the codebase to trace and diagnose production bugs, remaining on-call to support live incidents and minimise customer impact
- Wrote unit and integration tests following TDD practices throughout, contributed to code reviews, and mentored a junior hire
- Built interactive 3D facility visualisations using Three.js – including hangars, docks, car parks, and multi-storey buildings
