What I'm looking for

I seek roles building cloud-native, scalable web platforms where I can lead architecture, mentor engineers, and improve performance and cost-efficiency.

I am a Senior Software Engineer with 9+ years building web applications across Fintech, e-commerce, healthcare and B2B SaaS, focused on modern, scalable architectures and high-quality code. I design and implement microservices, serverless systems, data pipelines and performant frontend experiences using technologies like NestJS, React/Next.js, AWS, PostgreSQL and Kafka.

I drive improvements in performance and cost (for example, migrating legacy systems to serverless and reducing operational costs by 40%), introduce testing and TDD workflows, mentor junior engineers, and lead frontend and backend migrations to microfrontend and cloud-native architectures to deliver reliable, maintainable products.
