What I'm looking for

I seek engineering roles where I can build scalable front-end experiences, lead cross-functional delivery, mentor engineers, and use cloud-native microservices and strong testing/CI practices.

I am a seasoned Senior Software Engineer with 11 years of full-stack web development experience, specializing in front-end technologies while maintaining strong backend architecture skills.

I have built high-impact features and platforms—ranging from pet healthcare booking systems to enterprise-scale financial and IoT products—using React, Next.js, React Native, Java, Node.js, GraphQL, and cloud-native tooling.

My work has driven measurable outcomes: increased user engagement and bookings, faster anomaly detection and API responses, improved accessibility compliance, and reduced fraud response times through real-time pipelines and microservices.

I collaborate closely with product, design, and backend teams, champion testing and CI/CD best practices, and mentor engineers to standardize patterns and deliver reliable, scalable software.
