What I'm looking for

I seek roles where I can build scalable, AI-enabled SaaS platforms, mentor teams, and collaborate cross-functionally to deliver measurable product and business impact.

I am a senior full stack engineer with over 8 years of experience building scalable, cloud-native platforms for finance, tax compliance, and retail industries.

I design and implement microservices-based architectures using Java, Node.js, Spring Boot, Docker, Kubernetes, and AWS, and build responsive frontends with Angular and React to improve performance and user adoption.

I integrate AI-powered automation—ChatGPT APIs and RAG vector search—for document processing and NLP, improving classification accuracy and reducing manual review effort while optimizing throughput with Redis and Kafka.

I mentor engineers, drive technical roadmaps, and collaborate with product, QA, and DevOps teams to deliver reliable, secure SaaS solutions that connect engineering outcomes to measurable business impact.
