What I'm looking for

I'm looking to build secure, scalable, and maintainable backend or full-stack products, collaborate with cross-functional teams, and contribute across the SDLC through architecture, delivery, and continuous improvement.

I'm currently building and maintaining scalable Golang backend services at Hyperscal Digital Solution, including REST APIs, third-party integrations, and business-critical system architecture.

Previously at Cosmiqo, I developed Python enterprise applications and backend services, built REST APIs, designed ETL pipelines, integrated business systems, and improved performance through database optimization. I work across the SDLC, from requirements and database schema design through deployment, monitoring, testing, and production support.

I've delivered enterprise backend, data integration, and internal digital platforms using Golang, Python, PostgreSQL, Redis, Docker, Kubernetes, Airflow, and GCP. I care about secure, maintainable, business-oriented software and effective collaboration with cross-functional teams.
