(_) (_)A bit about me
I'm a full-stack developer working mainly in TypeScript, NestJS, and Next.js, with PostgreSQL and Docker underpinning most of what I ship. I've also worked across C#, Python, and PHP/Laravel, so I move comfortably between stacks depending on what a project calls for.
Outside of client work, I run daitsu.online, my personal portfolio site. I'm also currently building MumuTopup, a point-of-sale system for a multi-branch retail business integrating Omise, 2C2P, and the LINE Messaging API for payments and order flow, covering checkout, shared stock management, expense tracking, and daily closing procedures end to end.
I care about writing maintainable, well-structured code and enjoy taking a project from initial architecture through to deployment, including setting up CI/CD pipelines and handling database migrations and backups along the way.
What I work with
A curated set of tools I reach for regularly — not an exhaustive list.
Where I've worked
- Developed systems and applications following a microservices architecture to ensure modularity and scalability.
- Wrote end-to-end test suites validating API functionality, reducing production bugs and improving release confidence.
- Integrated services with various third-party APIs including payment gateways, video hosting platforms, file storage, Google APIs, and OpenStreetMap.
- Containerized microservices with Docker and managed deployment pipelines for consistent environments across development and production.
- Set up CI/CD workflows automating build, test, and deployment stages to streamline delivery and reduce manual overhead.
- Identified and resolved performance bottlenecks in API endpoints and database queries, improving response times and system throughput.
- Diagnosed and resolved critical internal software bugs, ensuring uninterrupted daily operations and smooth logistical workflows across the organisation.
- Actively monitored proprietary applications, identifying defects and implementing targeted fixes to improve overall stability and performance.
- Acted as primary technical resource for user-reported software problems, minimising system downtime and enhancing team productivity.
- Led end-to-end development and architecture as Lead Project Developer and Lead Database Designer, delivering robust, scalable software solutions from the ground up.
- Executed complex data migrations and provided vital ongoing database maintenance for large enterprise projects.
- Served as a versatile technical resource: active help desk support, diverse programming tasks, and maintaining multiple live applications simultaneously.
- Functioned as a reliable project maintainer and technical supporter, assisting senior teams in the successful delivery of various software initiatives.
- Contributed to data integrity and system performance by handling routine database maintenance and executing secure data migrations.
