Vetted Back-End developer in Canada (UTC-7)

I am a senior software engineer, developer advocate, and technology leader with experience working for startups, governments, Google, Andela e.t.c. I have built and lead engineers building for eCommerce, Edtech, Fintech, and Software as a Service to name a few. I love to write, code in JavaScript/Typescript/Python, and support clients with my can-do-anything spirit and clear communication skills. I enjoy mentoring and empowering engineering talent. I have had successes with this both at scale (thousands of developers) and with my direct reports as well. If you need to write clean JavaScript, intuitive Typescript, bug-free Python, build delightful REST APIs and SDKs, store data in relational or NoSQL databases, analyse data with SQL, containerize applications with Docker, run serverless container workloads on the cloud (AWS), organise code with monorepos, build/run pipelines with GitHub Actions / Jenkins, get cross-functional teams to deliver consistently and ship scalable products and services that solve business problems, then let's definitely talk!
