Senior full-stack software engineer focused on scalable JavaScript-driven systems and delivery.
IrelandWhat I'm looking for
I am a senior full-stack software engineer with 12 years of experience building systems to solve business problems, mainly using the JavaScript ecosystem. I deliver solutions from scratch and dive into existing codebases of any quality with a strong focus on shipping.
I have a passion for clean architecture, software engineering practices and patterns, continuous self-education, and mentoring others. My work spans frontend and backend technologies, CI/CD improvements, and performance optimizations.
I have led teams and shipped measurable product improvements — from increasing conversion rates for financial product flows to replacing spreadsheet workflows with robust tooling and improving UI performance by orders of magnitude.
I value pragmatic engineering, strong testing and API-first design, and building repeatable, documented processes that reduce defects and accelerate integrations.
