What I'm looking for

I'm looking to build scalable, high-performance web products where I can own end-to-end feature delivery, shape frontend architecture, solve complex product problems, and collaborate closely with product, business, QA, and distributed engineering teams.

I'm currently improving enterprise React workflows for Johnson & Johnson through Ascendion Digital Solutions, where I led refactoring and performance initiatives that reduced module load times by 30–40% and improved overall application performance by 40%.

Previously, as a founding engineer at Innex.ai, I established frontend workflows and code architecture for a UK healthcare GenAI copilot. I built responsive interfaces, data visualizations, and complex filtering experiences to make governance information easier to navigate.

I've delivered full-stack SaaS products and MVPs across healthcare, education, e-commerce, banking, and recommendation platforms. My work includes AI-powered educator feedback with OpenAI and Anthropic APIs, secure authentication, REST APIs, scalable MongoDB systems, and performance-focused React and Next.js applications.

I enjoy turning business requirements into practical technical plans, collaborating with distributed teams, mentoring frontend developers, and delivering reliable features on schedule.
