What I'm looking for

I’m looking for a fully remote senior/full-stack role where I can build scalable microservices and GraphQL platforms on Azure/AWS, focusing on real-time and data-intensive systems. I want strong CI/CD and IaC practices, and room to lead migrations and mentor teams.

I’m a Senior Software Engineer with 8+ years of experience designing and building scalable web applications and distributed systems, with a strong focus on performance, scalability, and maintainability. I build end-to-end products—frontend, APIs, and data pipelines—with clear ownership from architecture through deployment.

At Clarion Events, I engineered an SEO-optimized B2B customer portal using Next.js (SSR/ISR) and Azure services, cutting time-to-interactive by 55%. I designed microservices backends with Node.js and Go (gRPC, JWT auth, circuit-breaking), and delivered measurable results like a 40% reduction in API response time under peak load. I also built a high-throughput bulk import engine supporting up to 1 million records/hour while maintaining transactional integrity and error tracking.

I thrive on modernizing legacy systems into modular, independently deployable architectures. I led migrations from monolithic Django to micro frontends and decoupled UI layers using Next.js/module federation, reducing release bottlenecks by 60%, and I’ve consistently raised engineering quality through CI/CD with Azure DevOps, IaC (Bicep), automated testing (Jest/Cypress/Pytest), and code quality gates (SonarCloud). In earlier roles, I delivered real-time fleet tracking and telemetry pipelines across Azure/AWS—improving load times, data consistency, and release reliability.
