Business-focused builder and engineering lead with a strong product mindset
Team Lead / Staff Software Engineer
As team lead and staff-level individual contributor on one of the UK's fastest-growing female healthcare brands, I lead a cross-functional team spanning product, marketing, design, engineering, data, and sales. We own the customer journey from first touchpoint through purchase — ads, landing pages, and onboarding — and I am accountable for delivering against revenue targets set with leadership.
Working closely with senior leads, we identify conversion blockers and ship features to scale the business, growing the brand to 100,000+ customers.
Before joining SheMed, I was a hands-on engineering team lead on eMed's direct-to-consumer onboarding team.

Engineering Manager
Babylon was a digital health service provider that combined AI technology with the medical expertise of humans, delivering full access to healthcare.
My team had full ownership of Babylon's identity and eligibility stack. We holistically transformed the 'first mile' of the Babylon experience – how we reach out to a potential member and onboard them safely and securely so that they become paying customers.
Our work greatly contributed to scaling up the business to over $1bn in revenue.
Senior Software Engineer + Technical Product Manager
While working as a senior IC I picked up product management responsibilities to set direction and priorities for the team, engage with other stakeholders and map out requirements, and report back to leadership with regular updates, including a 2-minute live presentation for C-levels every month.

Technical Co-Founder
Payment Courier was born as a simple solution to a common problem: Splitting payments online. Sharing costs online is tough, whether it’s buying festival tickets or purchasing a new TV. The current payment methods are built on outdated logic - one person pays and waits for everyone else to reimburse them. With Payment Courier, consumers can simply share a link where recipients can easily pay their share directly to the merchant.
One needs to wear many hats at a startup. My main responsibilities included:
- Developing software components of Payment Courier.
- User experience and interaction design. Prototyping and user research.
- Copywriting (both for the UI and for marketing).
- Managing web and media appearances; designing and ordering company merchandise.
- Representing Payment Courier at fintech conferences and participating in startup pitch contests on stage, such as at MoneyConf 2018 and Money20/20 2018.

Software Engineer Contractor, Solutions Architect
Worked with three fellow developers in a Scrum team on supporting, maintaining and extending the IT infrastructure of a medium-sized business.
- Maintained and extended the company's monolithic web application. Developed all new components as loosely coupled services and incrementally extracted existing components to prepare for a future move to a microservice architecture.
- Proposed and developed several internal iOS applications and their respective APIs to handle specific business scenarios.
- Performed an initial security audit to reveal and patch vulnerabilities. Iteratively added features like multi-factor authentication and login attempt notifications to improve overall security.
- Performed UX research to uncover usability issues. Overhauled the most important user journeys based on research data and evaluated new design via user studies and A/B testing.
- Developed iOS and Android apps for company promotions.
- Communicated directly with employees. Held on-site seminars to introduce changes.

Software Developer
- Led a scrum team of 5 as we modernised a VoIP sign language interpretation system aimed at the deaf and hard of hearing. The service provides real-time online sign language interpretation from a phone app via a video connection, billed by the minute. We refactored the system's architecture to make it more resilient and scalable, and replaced major components to improve its reliability.
- Developed the iOS and web client apps of the same service.

Thesis Project
Authreq - turning iPhone into a hardware key
Authreq is a proposed scheme that allows users to prove their identity to a web service in a novel and intuitive way: by using their iPhone as a possession factor during authentication.
External service providers can send challenges to the user's device via Authreq whenever necessary, such as during login attempts. These challenges appear as push notifications. Users can sign these challenges with Authreq and send a digital signature back to the service provider. The service provider can then validate the signature with the user's public key, undeniably proving that the user allowed the transaction.
The scheme's usability and perceived security have been verified via a user study with 30 participants. Authreq was found to be more usable than all other popular 2FA solutions that it was compared with.
My thesis, the source code, and a live demo are available on the project's website.
