• Led the development of a new "App Store" and “App Surfaces” for external developers building on the Fanvue API. Defined internal standards and best practices for the API and shaped key design decisions.
• Analysed Discord and API log data to identify external developer pain points and needs, which helped the team prioritise, segment key users, and align prioritisation to business goals.
• Brought "product thinking" skills into play on these more technical projects by gathering data and understanding developer needs and requirements before starting.
• Integrated a new feature flag system to consolidate and replace 3 internal systems, providing an improved developer experience.
• Developed new data-driven methods to analyze Sentry errors, database stats, and the existing codebase, building an AI-driven analysis system to identify root cause issues in code structure, design, and development practices to provide actionable insights to the rest of the team.

• Within the first two months stabilized the platform by resolving critical P-1 issues that threatened major sales deals, spanning SQL optimization, a Flutter/iPadOS regression, and complex on-site network diagnostics. Proactively improved system reliability by introducing observability tools (Datadog, PostHog) and implementing structured testing processes.
• Led the end-to-end development of a new product that successfully converted two new customers in an adjacent market. Drove the full lifecycle from customer discovery to release, building it on a modern stack (Rust gRPC, Tanstack Start) designed for type safety, offline use, and strategic reduction of existing tech debt.
• Managed a complex integration with an enterprise customer's Oracle Fusion ERP system, liaising with third-party contractors and presenting strategy and progress updates to cross-functional steering groups and VP-level stakeholders.
• Spearheaded the development of a generative AI feature to automate the review of construction site photos, designing a "human-in-the-loop" system to mitigate risk. Proactively developed a PoC for bulk image analysis that was subsequently adopted by the sales team to showcase new data service capabilities.

Enterprise SaaS Platform & Team Scaling (2017-2020)

• Led the product and engineering strategy that took the company from early-stage development to securing a multi-year, $1.2M+ per annum SaaS contract.
• Hired and scaled the core product and engineering team from 0 to ~30, building the enterprise platform to support over 200 daily users in business-critical operations.
• Established the initial management structure, filling key roles across engineering, product, and design to support platform growth and delivery.

R&D Leadership & Product Diversification (2020-2025)

• Established and led a new R&D group to rapidly prototype and commercialize new data products, implementing a lean 6-10 week innovation cycle from discovery through design and development to release.
• Drove technical strategy by leading proof-of-concept projects, including a cost-effective knowledge graph system over PostgreSQL to evaluate its potential for unifying disparate company data sources (clinical trials, regulatory decisions).
• Created a specialized, auditable literature screening system for a global pharmaceutical client, requiring in-depth research of FDA requirements and consultation with legal and regulatory experts.
• Architected and delivered a unified, in-house consulting platform that integrated BI dashboards and collaboration tools. The platform improved project delivery and has been cited by customers as a key competitive differentiator.
• Building on this, spearheaded the end-to-end development of an advanced data synthesis platform for biomedical literature. This involved building a high-throughput ETL pipeline, optimizing complex queries on the OpenAlex database, and creating a lightweight RAG system to power a conversational interface.

• Developed the initial prototype for a consumer financial trading mobile app, which directly led to securing a seed investment of ~£750,000.
• Post-funding, defined the technical and organizational strategy, establishing a product team for rapid B2C prototyping (Python, React) and a data team to build a scalable, event-driven pipeline for future enterprise needs.
• Engineered critical platform components, including a configurable usage-based billing system and a Rust program that generated a type-safe TypeScript library from a PEG grammar for a visual expression builder.
• Architected "Iris," the company's unified data science delivery platform (Next.js, WorkOS), guiding it from initial proof-of-concept to a production system now used by customers.

• Led the 12-month, end-to-end development of "Fetch," a regionally award-winning factory operating system that addressed a critical software gap in the off-site construction industry.
• Designed a multi-faceted platform featuring a PWA for factory tablets and real-time status boards, delivering phased features for task tracking, drawing management, and an auditable Quality Management System (via Google Workspace) that enabled a single supervisor to oversee the entire facility. This underpinned one of the largest residential developments in the UK, providing 750 homes to the Royal Borough of Greenwich.
• Built the full-stack solution using PostgreSQL, PostgREST, Node.js, and React within an Nx Monorepo, implementing WebSockets for real-time updates and Service Workers for crucial offline functionality on the factory floor.

• Engineered a multi-tenant whitelabelling system for a bookkeeping SaaS (serving 1500+ UK SMEs), enabling resale by other accountancies and opening a new B2B revenue stream.
• Integrated banking APIs to automate the import of user bank statements as transactions, significantly improving user workflow.
• Owned the end-to-end development of the initial mobile app, from architecting the REST API and authentication system to building and deploying the hybrid front-end with React and Cordova.

• Engineered a reusable tablet application for a top-10 pharmaceutical client to create interactive visual walkthroughs of complex health economic data using SASS and jQuery.
• Developed the front-end for a scientific tool to design, run, and visualize complex Markov model simulations used in health economic modelling.
• Prototyped a mental health application in collaboration with a local psychotherapy practice to guide users through a series of self-help questions.

• Supported a major pharmaceutical study by conducting research on Hepatitis C across 28 countries and developing Python scripts to automate the structuring of hundreds of annotated findings.

Authored the documentation and designed and implemented a high-level API for Artifex's official WebAssembly PDF library after they contracted me based on the success of my popular open-source project, MuPDF.js (200+ GitHub stars).

Spent a couple of days building a simple online hangman game which I shared with my friends and family. Used a single-page React application with no backend and an obfuscated and compressed state representation in the URL for sharing, a hand-coded web canvas illustration, and the Web Share API for a rich mobile experience.
