🟒 Actively seeking Staff Engineer / Tech Lead roles β€” Let's talk!


🧠 About Me

"I don't just write code β€” I architect systems that scale, lead teams that deliver, and solve problems that matter."

I'm a Senior Software Engineer with 7+ years of experience designing and shipping high-performance, cloud-native, full-stack applications used by real users at scale. I specialise in distributed systems, AI integrations, and engineering leadership β€” and I'm actively growing toward a Staff / Tech Lead role where I can drive technical strategy and cross-team impact.

  • 🏒 Senior Engineer @ Accenture β€” leading full-stack architecture & cloud solutions for enterprise-scale clients
  • πŸ”­ Building production-grade systems with Next.js, React, Node.js, TypeScript & AWS
  • πŸ€– Integrating LLMs, RAG pipelines & AI APIs into real-world applications
  • πŸ“ Passionate about system design, distributed architectures, and engineering excellence
  • 🌱 Constantly upskilling in AI for Engineers, Kafka, Kubernetes & vector search
  • πŸ’¬ Ask me about React, Next.js, AWS, system design, microservices, or AI integrations
  • ⚑ Fun fact: I enjoy turning complex product requirements into reliable, maintainable systems.
