Backend work with real ownership, ideally in Go or Python on systems where performance and correctness actually matter, streaming, distributed services, infra, not CRUD behind a framework. And I'd like to keep learning into adjacent areas, so a role that stretches me technically instead of repeating what I already know.
Mukhtar Akere
@sirrobot01
I build high-performance Go and Python payment systems, APIs, and self-hosted infrastructure.
What I'm looking for
I've built production payment services, storefront workflows, and REST APIs across Crowdmade, Bitnob, Missinglettr, Jallows, and Khuddam.ng. At Crowdmade, I build Go microservices and internal tools for Shopify-integrated storefront and order workflows.
At Bitnob, I built a cross-country airtime and data subscription service in Django and Go, while improving platform stability and adding Prometheus and Grafana observability. I've also architected financial and reporting APIs with Django and Flask, and improved reliability with Redis, RabbitMQ, Docker, and Linux deployments.
I author and maintain decypharr, a high-throughput open-source file-streaming server written in Go, where I've reduced lock contention, fixed goroutine leaks using pprof, and added sparse-file caching with LRU eviction. I also build self-hosted developer infrastructure, including writ and protodex.
