Services
Specialized in full-cycle development across mobile, web, desktop, and DevOps, helping startups and businesses turn ideas into scalable, production-ready digital products.
Mobile App Development
Mobile surfaces for platforms, built with React Native and Expo: one codebase, iOS and Android, shipped through both stores. The app is never the whole product here, it is the surface of a platform, wired to the same backend, auth and data model as every other client, and released on the same cadence.
Website Development
Web frontends built on React, Next.js and Tailwind against a headless CMS: server-rendered, localized, structured for search engines and AI crawlers alike. The same discipline whether it is a marketing site or the web face of a multi-tenant platform: performance measured, content modelled, deploys automated.
DevOps Engineering
The infrastructure underneath the platforms: Kubernetes clusters on owned or cloud hardware, Dockerized services, CI/CD that ships on push, automated TLS, monitoring, scheduled backups and zero-downtime cutovers. The proof point is a production migration off managed cloud with no minute of downtime recorded.
Highlights
A curated showcase of some of my most impactful projects, built from the ground up across web, mobile, and desktop platforms. These works reflect my hands-on expertise in full-cycle development, and many continue to evolve under my ongoing support.

Where I have Been Employed and What I Have Done
Founder & Software Architect
Sep 2026 - Present • 1 month
Webanion is my full-time practice. I design and build AI-native platforms and the infrastructure that runs them, agent systems and the guardrails around them, MCP servers, multi-provider model routing, and durable orchestration for work that has to survive failure rather than restart from the beginning. The delivery stack is TypeScript end to end: NestJS and Node on the backend, Next.js, React and Vue on the front, React Native and Electron where a product needs to leave the browser, and self-hosted Kubernetes that I run and operate myself. I take on platform and AI engagements where the hard part is making the system reliable, not making it demo well.
Founder & Full-Stack Engineer
Feb 2021 - Aug 2026 • 5 years 7 months
At Webanion, I’ve worked as a versatile full-stack developer contributing to a wide range of internal tools, client applications, and cross-platform products. My responsibilities included mobile apps with React Native, frontend with React + Tailwind, backend with NestJS, and deployment using Docker.

CTO and Head of Engineering
Jun 2026 - Present • 4 months
Technical owner of architecture, infrastructure and technology direction for a platform around a thousand people use every day. Moved the entire live system off managed cloud hosting onto self-hosted Kubernetes with no recorded downtime: a hardened k3s cluster behind Traefik and a Cloudflare tunnel, per-service Kustomize manifests, gated production deploys and out-of-band secret management. A recurring cloud bill became infrastructure the business owns from DNS to disk. Three years on, the same architecture is still shipping without a rewrite, which is the real test of the early decisions.
Lead Engineer
Jan 2025 - May 2026 • 1 year 5 months
Turned a delivered product into one that ships predictably. Consolidated seven codebases into a monorepo with a phase-based release workflow and CI/CD on GitHub Actions: path-filtered builds, automated per-surface versioning and tagging, and gated production deploys. Shipped Prebooked, an embeddable booking widget published to npm that turns any partner site, hand-built, WordPress or Wix, into a booking channel with one line of script. Alongside it a public documentation site, Google Maps trip integration, per-domain CORS management, and continuous store submissions on both platforms across four versioned platform releases.
Full Stack Engineer
Apr 2023 - Dec 2024 • 1 year 9 months
Built the platform from the first commit to production, solo. A React Native app on Expo live on both stores, a customer enquiry site, operator and admin dashboards in React, and a NestJS and GraphQL backend on MongoDB serving all of them, so a booking made anywhere was visible everywhere at once. Square payments, Twilio messaging, live notifications and an offline mode. Containerised with Docker and deployed on DigitalOcean. The UI design was the only part I did not do myself.

Senior Full Stack Engineer
Apr 2023 - Present • 3 years 6 months
Fewer, larger and longer engagements, with end-to-end product ownership rather than task work. A UK booking platform taken from MVP to production across forty milestones and still running. An eighteen-month product engagement delivered milestone by milestone, eleven accepted. One client relationship across five contracts and nearly three years. Paid architecture consultations for founders deciding how to build. The work spans mobile, web, desktop and infrastructure: React Native and Expo, Next.js and React, Electron, NestJS and Node, PostgreSQL and MongoDB, Docker and Kubernetes, and increasingly the AI and agent layer on top of it. Top Rated with a 100% Job Success Score across 45 contracts, featured among Upwork's top React Native and React developers, with top 3% global performer recognition in 2024.
Full Stack Engineer
Dec 2021 - Mar 2023 • 1 year 4 months
Twenty-six contracts across React, React Native, Node.js and WordPress for clients in the US, the UK, Europe and the Middle East: features, fixes, deployments, UI builds and store submissions. Two things came out of it that outlasted any single contract. A 100% Job Success Score held from the start and never broken, and repeat business as a pattern rather than an accident, with several clients coming back three and four times.

Edulog • FullTime
Feb 2026 - Jun 2026 • 5 months
Missoula, Montana, United States • Remote
As part of the development team for Edulog Athena, I contribute to building and optimizing scalable software that helps school districts streamline bus routing, trip planning, and fleet management. My work spans debugging complex issues, developing new modules like Field Trip Management, improving admin dashboards, and ensuring smooth integration between routing algorithms, mapping systems, and parent/driver-facing portals. I collaborate across backend services, cloud infrastructure, and frontend interfaces to deliver efficient, reliable, and user-friendly solutions. My contributions directly support district operations by improving efficiency, safety, and communication for students, drivers, and parents.
As engineering lead at WorkflowFiesta, I owned an AI workflow automation product line end to end and directed a distributed engineering team. My work covered agent-driven workflow design, large language model integration spanning multiple providers, and durable orchestration so that long-running jobs resume instead of losing state on failure. Day to day this meant shaping architecture decisions, reviewing and unblocking the team's work, designing safe database migrations, and tracing problems from the interface down through services to the data model. I worked on a multi-tenant platform with per-tenant isolation, and partnered closely with product and QA to turn complex automation requirements into reliable, maintainable systems.
At TestFiesta, I work as a full-stack engineer focused on platform reliability, performance optimization, and resolving complex issues across a highly asynchronous, distributed system. I debug problems across the full stack, frontend rendering, Node.js backend logic, PostgreSQL queries, worker execution flows, and service-to-service communication. My responsibilities include designing safe database migrations, improving query performance through indexing and refactoring, and tracing UX issues from UI interactions down to backend and data models. I collaborate closely with QA and UI/UX teams to reproduce edge cases, analyze GitHub issues, and deliver high-quality fixes. Within my first month, I resolved over 50 complex issues, significantly strengthening system stability, scalability, and overall product performance.

Platform engineering on multi-tenant B2B SaaS: a shared-database architecture serving more than a thousand tenants with per-tenant credential isolation. Fine-grained authorisation modelled in OpenFGA across tenants, roles and resources. Durable workflow orchestration on Temporal so long-running jobs resume instead of losing state. Stripe subscription and metered billing. Kubernetes administration on GKE across staging and production, safe database migration design, and PostgreSQL query performance work through indexing and refactoring. TypeScript, Node.js, NestJS, Vue 3 and PostgreSQL throughout, with the shared-database and release patterns adopted across the engineering organisation.
Software Engineer

Joined on a defined JavaScript and Electron brief and grew out of it. Desktop application work in TypeScript alongside full-stack contributions across large existing codebases: cross-stack debugging, query and service-integration performance, and fixes shipped fast enough to be trusted with more scope.
