Hi, I’m Tom – a freelance software engineer based in Ireland.

I work closely with entrepreneurs and startups to shape, build, and launch their digital products. My work goes beyond just writing clean, scalable code — I bring a product-driven mindset that blends strategy, design, and technical execution to deliver results that are both functional and future-ready.

With over 8 years of experience in the industry, I’ve worked across a wide range of technologies including:

Frontend: React, Next.js, Tailwind CSS, HTML/CSS

Backend: Node.js, Express.js, Fastify, NestJS

Databases: MongoDB, PostgreSQL, Redis

DevOps: Docker, AWS (EC2, S3, Lambda), Railway, Vercel

Blockchain: Web3, Smart Contracts, Solidity, DeFi platforms

Automation & Scraping: Puppeteer, Playwright, Selenium

E-commerce: Shopify, custom checkout flows, plugin development

Others: RESTful APIs, WebSockets, cron jobs, Stripe integration

I take pride in being a collaborative partner — not just delivering code, but contributing to the bigger picture of your product’s success.

If you’d like to chat about a project, learn more about my workflow, or just connect — I’m always open to a conversation.

Cheers,
Tom C
