What I'm looking for

I’m open to fully remote/global roles where I can lead SaaS modernization and ship reliable, AI-enabled platforms—working with distributed Agile teams to improve performance, observability, and deployment velocity.

I’m a Senior Full-Stack Engineer with 10+ years of experience building scalable SaaS platforms, enterprise applications, APIs, and cloud-native systems across public-sector and product environments.

I bring deep hands-on expertise in React, Angular, Vue, Node.js, Python/FastAPI, and Java/Spring Boot, backed by strong cloud and delivery skills across AWS, Azure, Docker, and CI/CD automation. I’ve modernized legacy platforms with measurable outcomes, including reducing deployment time by 40% and improving incident response by 80%, while delivering AI-enabled capabilities that cut manual support workload by 1,000+ staff hours monthly.

In my current role as Technical Lead/Senior Full-Stack Engineer for Ontario Public and Business Service Delivery, I define architecture standards and technical roadmaps for identity, AI-enabled services, DevOps automation, and cloud-native delivery. I’ve led modernization into Oracle Identity Governance supporting 60,000+ users, built automation frameworks that improve release velocity, and developed production RAG search solutions using OpenAI APIs for secure, citation-backed enterprise knowledge retrieval.

I also thrive in distributed Agile teams—driving technical documentation, code reviews, production troubleshooting, and cross-functional delivery. Previously, I architected multi-tenant SaaS platforms with AI-powered product discovery and conversational search, and I strengthened observability and release consistency through CI/CD and Elasticsearch/Kibana dashboards.
