Senior Software Architect & Backend Engineer
I turn complex problems into systems that are secure, scalable and genuinely maintainable — 10 years across healthcare, government, e-commerce and multi-vendor marketplaces, built largely on .NET across AWS and Azure.
From FHIR healthcare platforms and microservices marketplaces to serverless social backends and a ride-hailing engine. Filter by domain or search the stack.
No projects match that filter.
Architecture-first, test-backed, cloud-native.
Microservices, Clean / Onion architecture, Domain-Driven Design, CQRS, event-driven and message-bus systems, well-versioned REST APIs.
C#, ASP.NET Core (.NET 6–10), Entity Framework Core, PostgreSQL, SQL Server, Redis, MQTT, Python services.
AWS (EC2, Lambda, RDS, S3, CloudFront, API Gateway, DynamoDB, SNS/SES), Azure (Container Apps, AD), Docker, CI/CD, zero-downtime & blue-green deploys.
Angular, Next.js / React, Tailwind; versioned APIs for Flutter, iOS and Android squads.
Open to senior architect and backend leadership roles.
