What I'm looking for

I seek roles building scalable, cloud-native systems where I can lead architecture, mentor engineers, and deliver measurable operational impact.

I am a Lead Full Stack Engineer with deep expertise in MERN, React Native, and Java Spring Boot, experienced in architecting enterprise-grade systems for logistics, e-commerce, and SaaS. I have led teams to deliver cloud-native web and mobile applications, designed microservices architectures with 99.9% uptime, and built real-time tracking used by over 100,000 users.

Throughout my career I have improved operational efficiency for enterprise clients, cut release cycles by half, scaled infrastructure to support thousands of active users, and mentored junior engineers in testing and best practices. I focus on building resilient, scalable systems using modern toolchains and cloud platforms to drive measurable business outcomes.
