What I'm looking for

I seek roles building scalable, secure web or mobile products with a collaborative, growth-focused team that values quality, mentorship, and real-world impact.

I am a specialized web and app developer with extensive experience building responsive frontends and scalable backends using modern JavaScript frameworks and mobile/desktop technologies. I deliver secure authentication systems, AI-driven integrations, and data-informed features, completing projects across MERN, React Native, Java, Kotlin, Firebase, PostgreSQL, and MongoDB while collaborating closely with clients to meet deadlines and quality goals.

My background includes freelance development and technical writing, junior and full-stack roles where I led Android app development, contributed to real-time auction platforms, and supported government revenue systems. I combine hands-on engineering, UI/UX prototyping in Figma, and technical documentation to produce reliable, user-friendly products that drive business impact.
