What I'm looking for

I’m looking for a backend role where I can build scalable Go services and REST/gRPC APIs with clean architecture, focusing on low-latency processing and real-time webhook/event integrations from end to end.

I’m a Golang backend developer with 3+ years of experience building scalable backend systems, REST APIs, and microservices. I enjoy turning real-time events and integrations into reliable services, with a strong focus on clean architecture and performance.

At Fitpass, I built scalable Golang backend APIs for the FITPASS Partner mobile application—covering workout listing, scheduling, booking, and reservation slot management. I also developed studio profile and gallery modules and ensured authenticated access to partner agreements and documents, along with robust logging and error handling.

At LeadsquaredCRM, I developed high-performance webhook APIs in Golang for real-time lead and activity processing, integrating CRM data pipelines with MoEngage using gRPC-based services. I optimize webhook payload validation, transformation, structured logging, and error handling to achieve low-latency, high-throughput delivery across the full SDLC.
