Full Stack Developer building scalable Python/React apps with REST APIs and Firebase-driven SaaS.

What I'm looking for

I’m looking to build and maintain high-performance products—owning features end to end, designing REST APIs, and shipping scalable React/Python systems with clean architecture and strong team collaboration, preferably in cloud-first environments.

I’m a results-driven Full Stack Developer specializing in Python, JavaScript, and React-based web application development. I focus on building scalable, maintainable, high-performance systems with clean architecture and a business-oriented mindset that connects engineering decisions to real impact.

I’ve developed and deployed multi-role SaaS web applications using React, Firebase, JavaScript, and Python/Flask. I built role-based dashboards, push notifications, and automated reporting—reducing manual workload by over 60%—and delivered platforms that improve onboarding speed, cutting onboarding time by 25% while maintaining satisfaction above 95%.

In production environments, I design RESTful APIs, integrate third-party services, and manage SQL and NoSQL databases across real workflows. From third-party API integrations and cloud functions to cloud deployment methodologies and team collaboration, I enjoy shipping reliable features, improving performance, and supporting long-term product sustainability.
