What I'm looking for

I seek senior technical roles where I can architect scalable cloud-native systems, lead cross-functional teams, and drive CI/CD and observability best practices in secure, growth-oriented companies.

I am a Senior Solution Architect and Full-Stack Engineering Lead with 12+ years designing distributed systems, decoupling monoliths into microservices, and delivering resilient serverless solutions. I translate complex business needs into scalable technical roadmaps that align product vision with engineering execution.

I have led modernization efforts across healthcare, fintech, and real estate SaaS domains—migrating legacy platforms to AWS Lambda and implementing trunk-based development with Azure CI/CD to accelerate releases and ensure zero-downtime deployments.

My technical leadership emphasizes production reliability and observability, leveraging Datadog monitoring, automated performance testing, and rigorous TDD to maintain 85–90% code coverage and reduce post-release defects. I also architect secure integrations with Salesforce and Mulesoft, and design high-volume transaction systems that eliminate concurrency issues.

I mentor engineering teams, enforce code quality governance, and build self-sustaining practices around CI/CD, RBAC, and encryption standards to deliver secure, multi-tenant SaaS platforms that scale.
