Daniel Nwangwu
@danielnwangwu
Seasoned backend engineer specializing in scalable systems, payments, and Golang-driven reliability.
What I'm looking for
I am a backend engineer with over 5 years of experience designing scalable microservices, high-performance APIs, and mission-critical financial and creator platforms. I focus on system reliability, observability, and SLO-driven operations while mentoring engineering teams and driving technical alignment.
My core technical strengths include Golang (4+ years), TypeScript, Python, PostgreSQL, distributed systems, and DevOps practices such as Docker, CI/CD, and observability tooling. I have built wallets, payment flows, and banking APIs with gRPC/REST, implemented double-entry accounting systems, and optimized performance using pprof and benchmarks.
I deliver pragmatic architecture and measurable impact: migrating monoliths to microservices, reducing feature delivery time through TypeScript adoption, and improving dashboard performance and platform uptime. I seek roles where I can lead technical design, improve reliability, and scale critical infrastructure.
