What I'm looking for

I’m looking for a role where I can own end-to-end architecture for scalable SaaS and AI-powered products, automate business workflows, and ship production systems that reduce manual work and deliver measurable user impact.

I’m a Full-Stack Software Engineer with more than 2.6 years of experience building scalable SaaS platforms, AI-powered products, and automation systems serving 20,000+ users. I focus on production-ready architectures that reduce manual effort and improve user experience.

At Smartbenefits, I architected serverless microservices with AWS Lambda and SQS to offload heavy I/O workloads, eliminating critical memory spikes. I also led end-to-end architecture of a remittance-linked health insurance product—building Partner/Ops/Customer platforms from scratch and automating policy delivery with WhatsApp-based issuance and integrated webhook APIs. In parallel, I built an AI chatbot using Vertex AI that resolves 1,000+ monthly medical queries at 85%+ accuracy, with self-updating agents to keep the knowledge base always current.

I’ve delivered measurable impact across HR workflows too, including automated quarterly reporting for 1,000+ HR professionals and reducing workload by 30% through in-portal claim submission and Celery-based onboarding/offboarding automation. I enjoy shipping features end-to-end—dashboards, feedback loops, and background processing—while maintaining solid engineering practices and a fast, solution-driven mindset.
