Staff-level product engineer with 10+ years building across the full stack. I move fluidly between customer discovery, product strategy, UX, system architecture, and engineering — taking end-to-end ownership from the first user conversation to what ships in production.

My background as a founder and technical lead has sharpened the judgment that senior engineers need: knowing when to move fast, when to slow down, how to make architectural calls that hold up over time, and how to align strong engineering with good outcomes for the business.


Skills

Full-Stack Engineering

React, Next.js, TypeScript, React Native, Node.js, Express, GraphQL, REST, HTML/CSS. I build fast, accessible, maintainable interfaces and design clear service boundaries on the backend. Comfortable owning the entire delivery surface — frontend, API, data layer, and infrastructure — without handing off.

Systems Architecture & Infrastructure

Extensive experience designing production systems end-to-end: relational schema design, containerised services, event-driven architectures, and cloud infrastructure on Google Cloud and AWS. I make architectural decisions that are easy to reason about in production and flexible enough to evolve with the product.

Technologies: PostgreSQL, Redis, Docker, Kubernetes, Google Cloud, AWS, Cloudflare, CI/CD pipelines

Product & UX

I work directly with users, uncover the real problem, and translate that into focused product strategy, intuitive UX, and coherent design systems. I've been the sole product owner across multiple companies — shaping direction, making trade-offs, and keeping engineering and commercial goals aligned.

Technical Leadership

Led engineering teams through hiring, mentoring, and process development. Comfortable setting technical direction, making architectural calls, and bridging the gap between engineering and the rest of the business. At Thespie, I owned the entire engineering function; at Korda, I was the sole technical founder.


Experience

Korda — Founder & CEO (2023 – 2026)

Took a VC-backed music business platform from idea to revenue as sole technical founder. Raised £250k+, defined the product strategy, led UX research and design, and built the entire stack — frontend, backend, architecture, and cloud infrastructure — with full end-to-end ownership throughout.

Entrepreneur First — Founder in Residence (2022 – 2023)

Selected onto EF's global programme. With fewer than 3% of applicants accepted, EF invests into exceptional individuals before any business idea exists. Worked across co-founder matching, market validation, and early fundraising — developing the ability to test working relationships at speed and communicate a vision clearly enough to convince the right people to build with you.


Thespie — Lead Engineer (2020 – 2022)

Led the engineering function at a theatre discovery platform, owning the full stack, cloud infrastructure, and key architectural decisions. Grew and mentored the team through technical hiring, established development processes, and kept the product shipping through the disruptions of the pandemic and into recovery.

JAAK — Software Engineer (2018 – 2019)

Built rights-management infrastructure at the intersection of blockchain and the music industry, working alongside major labels and rights organisations. An early, rare opportunity to design and ship production systems in web3 — across React, Next.js, Node.js, GraphQL, AWS, and Solidity — before the space had established patterns.

Trippin — Software Engineer (2017 – 2018)

Owned the full lifecycle of an iOS travel app — from product discovery and technical scoping through to App Store launch. Sole engineer responsible for all technical decisions, building across React Native and a type-safe event-sourced backend.

Warner Music Group — Recording Artist & Songwriter (2010 – 2015)

Signed a five-album major record deal, wrote and collaborated with world-class artists, and earned a 3× platinum record. Performing and creating at that level instilled a standard of craft, a tolerance for ambiguity, and a discipline under pressure that I carry directly into my work in software.
