What I'm looking for

I’m looking to build end-to-end web and cloud platforms where performance, usability, and maintainable design matter. I want to own backend APIs and real-time integrations, collaborate across frontend and infrastructure, and ship reliable products.

I’m a full-stack developer with experience building customer-facing platforms, internal tools, backend systems, APIs, and cloud-backed applications. I focus on performance, usability, maintainable system design, and end-to-end delivery—working across frontend, backend, infrastructure, messaging, and system integration.

At Macs Ltd, I built the Meter MACS Portal, owning development across frontend, backend, and cloud infrastructure on AWS (ECS, VPC, RDS, S3) and integrating with existing operational workflows. I also developed messaging-driven workflows with RabbitMQ for device communication and real-time updates, and delivered a Go/gRPC backend service that reduced dashboard load times from 8–12 seconds to around 1.2 seconds.
