# Work with a technical founder. Source: https://www.gaz.dev/hire-me I’m a hands-on builder with experience founding, running, growing and selling a software business. I can build your app from scratch, solve a technical problem, or help with product decisions, customers, operations and the next stage of your business. Based in the UK. Working with people worldwide. ## The product and the business behind it ### Product delivery Work out what to build first, test the uncertain parts and get a useful version into people’s hands. - Product planning and prototypes - Web products and SaaS - Launches, rebuilds and ongoing development ### Apps and systems Build for the devices your customers use, with the data, services and integrations behind the app. - iPhone, iPad, Android and desktop apps - APIs, databases and permissions - Payments and third-party integrations ### Applied AI Give AI a useful job, then build the checks and controls it needs to work in a real product. - Assistants and agents - Search, documents, voice and generated media - Evaluations, monitoring and cost control ### Cloud and leadership Keep the product running and make informed decisions about the business around it, from costs and hiring to growth and an eventual exit. - Hosting, security and cloud operations - Technical and business advice - Scaling, turnaround and exit preparation ## Ways to work together ### Work directly with me I take a product from the first decisions through build and launch, or own a focused piece of work that needs sorting out. ### Add me to your team I stay hands-on with your team, writing code, solving problems and improving the product or the systems behind it. ### Work with me as an adviser We work through product and business decisions together, whether you’re looking for product–market fit, improving cash flow, scaling or preparing for an exit. ## Capabilities ### Planning and product decisions Turn a rough idea into a clear first version and a practical plan for building it. - Discovery, workflows and prototypes - Feasibility, technical risk and architecture - Roadmaps, estimates and build-versus-buy decisions - Existing codebase and system reviews ### Web products Build the customer-facing product and the tools needed to operate it. - Multi-tenant SaaS and subscription products - Portals, internal tools and compliance workflows - Dashboards, reporting and real-time collaboration - Websites, e-commerce, offline web apps and browser extensions ### Mobile and desktop apps Build native or cross-platform apps and take them through release. - Swift and SwiftUI for iPhone, iPad and macOS - Android, React Native and Expo - Windows, Electron and cross-platform desktop apps - Store releases, notifications, offline data and backend integration ### AI features Make information easier to use and repetitive work easier to complete. - Assistants, tool-using agents and workflow automation - Knowledge search, RAG and document processing - Voice, transcription and generated media - Conversational interfaces and decision-support tools ### AI in production Take a promising prototype into a product you can monitor and maintain. - Model selection, tool calling and MCP integrations - Evaluations, monitoring and provider fallbacks - Permissions, human approval and privacy controls - Latency, resilience and cost optimisation My work is applied AI. I do not train foundation or frontier models. ### Data and integrations Connect the product to the data and services it depends on. - APIs, databases, search and data migrations - Queues, background jobs and real-time systems - Authentication, permissions, tenant isolation and audit trails - Payments, messaging, files and legacy integrations ### Hosting and operations Set up the production environment and keep it running after launch. - AWS, Vercel, Railway, Cloudflare, serverless and Docker - Deployments, DNS, databases and storage - Monitoring, backups, security and recovery - Performance, cloud costs and ongoing maintenance Software and cloud support is during agreed hours. It does not include automatic 24/7 cover, helpdesks, consumer IT, hardware repair or cabling. ### Business growth and exit preparation Practical advice from building, running and selling my own software business, and helping others recover and grow. - Customer feedback, product–market fit and decisions to pivot - Budgets, cash flow, costs and hiring decisions - Scaling a software business and recovering a struggling one - Preparing for an exit and working through an acquisition ### Technical leadership Work alongside your team when you need senior technical judgement and someone who can also build. - Founding engineer, fractional CTO or embedded technical lead - Architecture, delivery planning, hiring and mentoring - Stalled products, fragile systems and technical debt - Technical due diligence, acquisition preparation and handover ## How delivery works 1. **Talk it through**: Tell me the idea, who it’s for and where you’ve got to. We work out whether I’m a good fit. 2. **Decide what comes first**: I help define a useful first version, test the risky parts and set out the approach. 3. **Build and review**: You see working software as it develops, so we can make decisions with something real in front of us. 4. **Launch and keep going**: I help get the product into use and can stay involved in its operation and next versions.
