Senior full-stack engineer building scalable AI-driven web platforms and SaaS products.
IrelandWhat I'm looking for
I'm a Senior Full Stack Engineer focused on building scalable, AI-enabled web platforms and multi-tenant SaaS products with an emphasis on performance and accessibility.
I led development of a GenAI-powered e-commerce, education, and SaaS platform serving 10K+ active monthly users, built 30+ RESTful microservices, and shipped solutions that improved engagement and load performance across projects. Previously I delivered healthcare and enterprise systems serving 1M+ monthly users and published open-source tooling adopted by thousands.
I work across modern frontend and backend stacks (React/TypeScript, Node.js, NestJS, Next.js, Prisma), cloud-native infrastructure (AWS, GCP, Azure), and CI/CD/IaC. I prioritize TDD, observability, mentoring junior engineers, and turning rapid MVPs into robust production systems.
