What I'm looking for

I seek roles building scalable web/SaaS products where I can own end-to-end features, improve performance, and work with secure authentication and cloud integrations.

I am a Full Stack Developer with 2+ years of hands-on experience building production-grade web applications using Next.js, React.js, Node.js, and NestJS. I focus on delivering scalable features for CRM and SaaS products, emphasizing security, performance, and real-user impact.

My work includes designing RESTful APIs, implementing authentication systems (JWT, OAuth 2.0, SAML), and optimizing databases such as PostgreSQL and MariaDB to reduce API response times by about 30%. I integrate cloud and third-party services (AWS, Twilio) to support real-world workflows and automations.

I take ownership of end-to-end delivery, have been recognized with the PerfoMaven Award for consistent high-quality delivery, and continuously improve systems through thoughtful architecture, performance tuning, and secure design.
