What I'm looking for

I’m looking to build reliable, scalable SaaS and cloud-native backends with AI-assisted workflows—partnering with product and engineering teams to ship observable systems, strong APIs, and operational intelligence that reduces manual work.

I’m a Senior Full-Stack Engineer with 12+ years building scalable SaaS platforms, AI-assisted workflows, and cloud-native backends across distributed teams. I focus on backend platform engineering, designing reliable APIs and distributed services that teams can run confidently at scale.

At Altura AI, I led development of scalable backend services and AI-assisted workflow systems using Python, FastAPI, PostgreSQL, and AWS. I designed RAG-based document intelligence pipelines, built asynchronous AI processing infrastructure with AWS SQS, and improved deployment reliability and operational visibility with CloudWatch dashboards, Prometheus metrics, and distributed tracing.

Previously at Paybridge Cloud, I re-architected Node.js microservices and PostgreSQL query layers to improve API responsiveness for high-volume transaction systems. I implemented RBAC and audit logging aligned with SOC2 and GDPR, and delivered GraphQL gateway services to support internal analytics and operational reporting.

Earlier, I developed SaaS backends and customer-facing web applications as a software consultant in Ireland, and started my career at Intact building ERP-style audit and workflow automation features. I’m motivated by engineering standards, observability, and mentoring—helping teams ship dependable systems with clear ownership and strong execution.
