What You'll Receive
Full Description
You have an idea. You need it built properly — not patched together, not handed off to a generalist, but engineered by someone who understands both the full-stack foundation and the AI layer on top of it.
I'm Zinn Digital, a full-stack and AI developer based in London, England. I build web applications and AI-powered software that are clean, scalable, and ready to support a real business. Whether you need a single-page app with a smart AI feature integrated into it, a functioning multi-page web application, or a complete SaaS product with advanced AI capabilities, I work with you from planning through to delivery.
Every project starts with understanding your goals. I don't build in a vacuum — I ask the right questions, discuss your requirements thoroughly, and only then begin development. That clarity is what keeps projects on time and on brief.
**What I build:**
Bespoke full-stack web applications, AI-powered websites and SaaS platforms, API development, automation and chatbot solutions, dashboards, CRMs, ERPs and business systems, LLM integrations and RAG pipelines, NLP-based applications, e-commerce features and payment gateway integrations, and third-party integrations.
**Technologies I work with:**
JavaScript, Python, React JS, Next JS, Node JS, Flask, Ruby on Rails, MySQL, PostgreSQL, Firebase, Supabase, MongoDB, OpenAI GPT, LangChain, TensorFlow — and more depending on your project's needs.
**How it works:**
Once you place your order, share your project details and I'll get started. I communicate continuously throughout every phase — requirements gathering, proposal, design, development, testing, and delivery. For larger projects, I divide work into clear milestones with defined scope and timelines so you always know exactly where things stand.
**What's included across all tiers:**
Full source code is delivered with every order. Revisions are unlimited. You also receive planning and consultation as part of the process — I want to make sure what I build is exactly what you need.
**Post-delivery support:**
I provide free support for three months after project completion. You're not left alone once the files land in your inbox.
**Who this is for:**
Startups building their first product, businesses adding AI capabilities to an existing platform, founders who need a technical partner who communicates clearly, and teams who want reliable, high-quality development without the guesswork.
If you're unsure which tier fits your project, send me a message before ordering. I'm happy to discuss scope and give you a clear estimate.

Frequently Asked Questions
The Starter tier suits a single-page app with one AI feature integrated — ideal for proof of concepts or simple tools. The Growth tier is right for a functional multi-page application ready for real use. The Enterprise tier covers complete product development including advanced AI, integrations, dashboards, SaaS platforms and larger systems. If you're unsure, message me before ordering and I'll give you a clear recommendation.
Yes — I offer complete development including UI/UX design, responsive high-quality frontend development, backend development, and AI integration. You don't need to bring a separate developer for any part of the stack.
Once you place your order, please share your project details — including any logins for an existing system if applicable, a description of what you want built, any design references or brand assets, and your key requirements. The more context you provide, the faster I can begin. I'll reach out via order chat if I need anything further.
A simple AI integration takes around three to four days. A medium-sized web application typically takes one to three weeks. Enterprise applications with complex features can take ten to fifteen weeks. Each tier's delivery time reflects a realistic estimate for that scope. Message me for a precise estimate on your specific project.
I divide larger projects into clear milestones with defined scope, cost, and timelines. Once each milestone is completed and approved by you, we move to the next. This keeps everything transparent, manageable, and easy to track throughout the build.
I work with a wide range of AI models and frameworks including OpenAI GPT, Llama, Claude, CoPilot, LangChain, TensorFlow, and more. I can implement text generation, chatbots, NLP applications, text-to-speech and speech-to-text, RAG pipelines, LLM integrations, custom model fine-tuning, and automation — depending on what your project needs.
Yes. I provide free support for three months after project completion across all tiers. If you need extended support beyond that, the Extended Support add-on is available.
Yes — full source code is included with every tier at no extra cost. You own your codebase completely.
