About me

Who is Roshan?

I'm a versatile Full Stack Software Engineer with over nine years of experience creating efficient, scalable and user-friendly applications. At Dzango I've used a diverse tech stack to deliver products that meet real business needs.

My work spans mobile apps, web apps, backend APIs and DevOps. I enjoy tackling complex problems, working directly with clients on requirements, and seeing a product all the way through to release and maintenance.

Work process

How I work

The same loop on every product, from a first conversation with the client to a release that keeps running.

  1. 01

    Discover

    Requirement and feature analysis with the client, so we build the right thing.

  2. 02

    Design

    Architecture, data models and reusable components that the whole team can build on.

  3. 03

    Build

    Mobile, web and backend implemented side by side, with tests where they matter.

  4. 04

    Ship & maintain

    Dockerized deploys to AWS through CI/CD, then store releases and ongoing supervision.
