Emmanuel

Senior Backend Engineer with 6+ years building high-throughput, fault-tolerant platforms in fintech, telecom VAS, and payments. I design and ship production systems in Golang and Node.js/TypeScript, with deep experience in distributed systems, billing platforms, USSD/SMS at scale, and SMPP protocol engineering. I currently lead a team of 6 engineers on platforms processing 7.5M+ daily SMS messages and 536K+ daily USSD transactions. I have a strong track record of replacing costly third-party dependencies with reliable in-house infrastructure—telco aggregation, FTTH billing, bulk SMS, and enterprise VAS APIs—while improving SLAs, revenue controls, and operational visibility. What I bring to client projects: clear architecture, production-grade APIs and workers (Redis, queues, circuit breakers), telco and payment integrations (REST, SMPP, SOAP), and hands-on leadership through code review, incident response, and delivery ownership. I work well with product and ops teams and communicate progress and trade-offs plainly. Open to remote backend and platform work: greenfield builds, scaling existing services, billing/charging systems, SMS/USSD/VAS platforms, and fintech payment flows. Based in Lagos, Nigeria; comfortable collaborating across US, Canada, UK, and Europe time zones.
