What I'm looking for

I am looking for a role that allows me to leverage data to improve health outcomes, ideally in a collaborative environment focused on wellness and fitness.

I am a Computer Science graduate with a strong background in backend technologies and cloud infrastructure. Currently, I serve as a Tech Lead at Astron Members, where I oversee the development of a digital platform serving over a million users. My focus is on delivering efficient, cost-effective code without sacrificing performance.

Throughout my career, I have prioritized impact. Notably, I engineered a mobile application API that increased Customer Lifetime Value (LTV) by 20% and optimized server-side code to reduce operational costs by 30%. I also implemented centralized task management workflows that eliminated our recurring bug backlog. Previously, at Upplay, I led the architecture and deployment of the company's core system using Laravel and Angular.

My technical stack includes PHP, Laravel, Node.js, and AWS (Lambda, DynamoDB). Beyond coding, I have experience in data engineering, having developed an end-to-end architecture for churn prediction analysis during my academic thesis. I am looking for a challenging remote opportunity where I can apply my leadership skills and technical expertise to solve complex problems.
