What I'm looking for

I am looking for a dynamic contract-to-hire role where I can contribute to long-term projects with rapid turnaround and strategic insight.

I am a Full Stack Developer and System Administrator with over 3 years of experience in designing and deploying scalable web applications and managing robust server infrastructures. My work has earned me recognition as a Top 3% Freelancer on Upwork, where I have maintained a 100% Job Success rate and logged over 1000 hours. I specialize in PHP, Laravel, React, Next.js, MySQL, and Linux, and I have a proven track record of delivering high-performance solutions for SaaS platforms, PDF utilities, and AI-integrated applications.

Throughout my freelance career, I have successfully completed over 14 projects, consistently receiving 5-star reviews from clients. I take pride in my ability to develop and maintain full-featured SaaS platforms, integrate complex external APIs, and build custom tools that meet specific client needs. My selected projects include an AI-driven SaaS app utilizing Laravel and OpenAI API, and an online PDF editor that allows users to compress, sign, and unlock documents. I thrive in dynamic environments and am eager to contribute my skills to long-term projects that require rapid turnaround and strategic insight.
