Building beyond
the interface.

I’m a Product Engineer with more than six years of experience turning product and business requirements into software people can actually use.

My foundation is deeply rooted in frontend development, but my work increasingly extends across the entire product lifecycle — from shaping requirements and designing application architecture to building interfaces, APIs, integrations and production systems.

I think beyond the ticket: why we’re building something, how it fits into the wider product, which trade-offs we’re making and how it evolves after release.

Financial products demand more from engineering.

For more than four years, I’ve worked on digital banking and payment products where reliability, transaction accuracy and system integration are fundamental product requirements.

From ambiguity to production.

  1. 01

    Understand the problem

    I start with the business problem, users and constraints before deciding what the software should look like.

  2. 02

    Shape the product

    I translate requirements into practical product scope, user flows and technical decisions.

  3. 03

    Engineer the solution

    I work across frontend, mobile, APIs, backend systems, integrations and data to build the product.

  4. 04

    Ship and iterate

    Production is part of engineering. I care about deployment, reliability, feedback and how the product evolves after release.
