What I'm looking for

I seek roles building scalable web platforms where I can lead technical execution, improve performance, mentor developers, and implement cloud and CI/CD best practices.

I am a Senior Full Stack Developer with over 8 years of experience designing, developing, and deploying scalable web applications for eCommerce, SaaS, and enterprise clients. I lead technical execution that aligns with business objectives, optimize performance (reducing page load time by 35%), and implement CI/CD pipelines that cut release cycles by 50%.

I mentor junior developers (increased team productivity by 20%), build cloud-based solutions serving 50K+ active users, and deliver measurable results like improved conversion rates and faster transaction speeds. I am passionate about continuous improvement, cloud technologies, Web3, and collaborative teamwork.
