I help startups and businesses launch mobile apps that don't need a rebuild six months after launch — built right the first time, in Flutter, React Native, or native Swift/Kotlin, whichever fits your product best. I'm a Senior Mobile App Developer with a 5.0-star rating across 22 projects, specializing in Flutter, React Native, iOS (Swift), and Android (Kotlin). Because I work natively as well as cross-platform, I can recommend the right technology for your product instead of forcing every project into the same stack — based on your requirements, existing codebase, performance needs, and long-term scalability. What I build: - Flutter & React Native apps, or native iOS/Android when performance demands it - Mobile MVPs and custom apps from Figma designs or a spec - Backend integrations — REST APIs, Firebase, Supabase, third-party APIs - Real-time features, chat, push notifications, auth & social login - In-app payments, subscriptions, maps & location features - App Store & Google Play deployment, app migrations & rebuilds - Bug fixing & performance optimization on existing apps Whether you have a complete spec, Figma designs, an existing codebase, or just an idea, I can help you plan and build the right mobile solution. 📩 If you're looking for a mobile developer who can handle both iOS and Android — and tell you honestly which stack fits your product — send me a message. I'll review your idea and suggest the best approach before you hire me.

I'm a Senior AI Engineer specializing in building AI driven SaaS platforms, AI Agents, workflow automations and AI-powered search and chat with RAG, backed by a deep mathematical and practical understanding of how LLMs actually work under the hood. "Before finding Pete, we ran through numerous freelancers on Upwork that over-promised and under-delivered. Pete is the complete opposite. He consistently delivers to a high standard and is a pleasure to work with." - Simon Hammer, VP of Vimbly I think I'm very easy to work with as I'm very friendly, self-motivated and professional. I invest myself in making projects successful and am very adaptable to adjust to the needs of the project including learning all about the unique context of the business, the product, the customers and the problems they are trying to solve. I'd also say I'm very good at understanding complex systems, thinking outside the box, learning new things quickly and analyzing things from multiple perspectives to ensure solutions are thought through before committing to them. I've spent 20+ years building and leading web and SaaS platforms, mobile apps and AI software for technology companies and startups across the UK, US and Europe, including Microsoft, Sopra Steria, Highways England, the NHS and major European airlines and banks. I've built complex cloud and data platforms, high-performance applications serving millions of users and systems processing millions of dollars, including in regulated environments handling sensitive data. I've also worked closely with founders through investment, growth, scaling and pivots, solving the technical and product challenges that come with each stage. My technical experience includes TypeScript, JavaScript, LLMs, RAG, AI agents, agentic workflows, AI automation, workflow automation, prompt engineering, embeddings, vector databases, semantic search, MCP, tool calling, structured outputs, AI evaluation, OpenAI, Anthropic, LangChain, React, React Native, Next.js, Angular, Node.js, NestJS, Python, REST APIs, PostgreSQL, MongoDB, Redis, Supabase, Firebase, Docker, Kubernetes, AWS, GCP, Azure, Cloudflare, CI/CD and GitHub Actions. I also have a bachelor's degree in Mathematics and Computer Science, specialising in machine learning. I've studied the mathematics behind LLMs in depth and built models myself, giving me a deeper understanding of how they actually work, how to get the best from them, and where their limitations and common pitfalls lie. If you have an AI project you want to get moving, an existing product that needs improving, or just want to talk through what's possible, feel free to get in touch. 𝗙𝗔𝗤 𝗪𝗶𝗹𝗹 𝘆𝗼𝘂 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗱𝗼 𝘁𝗵𝗲 𝘄𝗼𝗿𝗸 𝘆𝗼𝘂𝗿𝘀𝗲𝗹𝗳? Yes. I'm an independent freelancer, not an agency. Unlike some other Upwork users, the person you speak to is the person designing and building your project. I don't hand the work off to junior developers or outsource it behind the scenes. 𝗖𝗮𝗻 𝘆𝗼𝘂 𝘁𝗮𝗸𝗲 𝗔𝗜 𝗳𝗿𝗼𝗺 𝗽𝗿𝗼𝘁𝗼𝘁𝘆𝗽𝗲 𝘁𝗼 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻? Yes. A big part of my work is turning AI prototypes and ideas into reliable, production-ready software. That means dealing with the things demos often skip: integrations, data, testing, evaluation, monitoring, fallbacks, security, scalability and the surrounding software needed to make the whole thing dependable. 𝗖𝗮𝗻 𝘆𝗼𝘂 𝗵𝗲𝗹𝗽 𝗶𝗳 𝗜'𝗺 𝗻𝗼𝘁 𝘁𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹? Absolutely. I've spent years working directly with founders, business owners, product teams and other non-technical stakeholders. I'm good at explaining complicated technical decisions, options and trade-offs in plain English without drowning people in jargon. 𝗖𝗮𝗻 𝘆𝗼𝘂 𝗿𝗲𝘃𝗶𝗲𝘄 𝗮𝗻 𝗲𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝗔𝗜 𝗽𝗿𝗼𝗷𝗲𝗰𝘁? Yes. I can review your architecture, codebase, AI implementation and security, identify potential problems and recommend what I'd change. 𝗖𝗮𝗻 𝘆𝗼𝘂 𝗯𝘂𝗶𝗹𝗱 𝗔𝗜 𝗰𝗵𝗮𝘁 𝗼𝘃𝗲𝗿 𝗼𝘂𝗿 𝗼𝘄𝗻 𝗱𝗮𝘁𝗮? Yes. I build RAG-powered AI search and chat systems over private documents, databases and business knowledge. 𝗖𝗮𝗻 𝘆𝗼𝘂 𝗮𝗱𝗱 𝗔𝗜 𝘁𝗼 𝗮𝗻 𝗲𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝗦𝗮𝗮𝗦 𝗽𝗿𝗼𝗱𝘂𝗰𝘁? Yes. I can add AI workflows, agents, document processing, search, automation and other AI features to existing platforms without unnecessarily rebuilding everything. 𝗖𝗮𝗻 𝘆𝗼𝘂 𝗽𝗿𝗼𝘃𝗶𝗱𝗲 𝘁𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗹𝗲𝗮𝗱𝗲𝗿𝘀𝗵𝗶𝗽 𝗮𝘀 𝘄𝗲𝗹𝗹 𝗮𝘀 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁? Yes. I can lead the technical side of a project, make architecture and technology decisions, review existing teams and codebases, or provide fractional CTO support. I'm equally happy being brought in for a specific piece of hands-on development. 𝗗𝗼 𝘆𝗼𝘂 𝗼𝗻𝗹𝘆 𝘄𝗼𝗿𝗸 𝗼𝗻 𝗔𝗜? No. AI is my current specialism, but it's backed by 20+ years of full-stack SaaS engineering, so I can work across the frontend, backend, APIs, databases, infrastructure and deployment as well as the AI itself.

I can help with: - SaaS MVPs and product features — planning, building, extending, and iterating on web applications - Existing product development — adding functionality and improving established applications - API integrations and internal workflows — connecting services and implementing the systems around the core product - Technical and product ownership — translating business requirements into sensible implementation decisions Relevant work includes an Agent-Assisted GTM & Distribution Platform, a Brand Ambassador SaaS Platform, a multilingual justice-data platform, and complex ecommerce systems. My background includes hands-on development alongside product/project leadership experience, so I’m comfortable moving between product requirements, technical decisions, stakeholder communication, implementation, and delivery. If this sounds like a good fit, I’d love to hear about your project. Send me a short description of what you’re working on, along with any relevant URLs or a repo if available, and I’ll let you know how I’d approach it.
