Build and design highly scalable backend services and APIs in Go/Java/Python/Node.js, working with relational and NoSQL data stores, writing tests, reviews, and automation, and guiding developers while coordinating delivery with product/engineering.
"“Develop high-quality APIs, and services.”"
Tech stack maturity
Mainstream Modern
The stack centers on widely adopted contemporary backend technologies like Go, Java, Node.js, Python, APIs, relational and NoSQL databases, and unit testing, which aligns with mainstream modern development rather than bleeding-edge or legacy approaches.
