AI Software Development | Fullstack + Frontend + UI/UX | 10+ years | Top 2% on Upwork I help SaaS founders, startups, and agencies build AI-powered products end to end, from the AI logic to the fullstack build to a clean, user-friendly interface. Most teams have to hire three separate people for that. With me and my team, the AI, the engineering, and the design come from one place, so your product actually ships and works well together. Over the last decade I have delivered 100+ web and SaaS products, and today I bring that same craftsmanship to AI development, building chatbots, assistants, automation, RAG systems, and custom AI features that are genuinely useful, not just buzzwords. Most "AI" projects fail because the strategy or the build quality is wrong, not the model. That is exactly where deep product and engineering experience makes the difference. What I work on: AI Software Development: AI chatbots and virtual assistants, OpenAI, Claude, and Gemini integration, RAG-based knowledge assistants, AI agents and workflow automation, AI SaaS tools, and custom AI features inside existing products. Fullstack & Web App Development: Full SaaS platforms, CRM systems, admin panels, data-heavy dashboards, APIs, and complex workflow applications, frontend and backend. Frontend Development: React.js, Next.js, Angular, Vue.js, TypeScript, Tailwind CSS, responsive UI, and Figma to pixel-perfect implementation. UI/UX Design: SaaS dashboards, web app design, landing pages, wireframes, prototypes, design systems, and product redesigns in Figma. MVP Development: I have helped 30+ founders go from idea to a working product, fast and structured, now often with AI at the core. QA and Delivery: Every project goes through structured testing and screen-wise review before delivery. On AI tools: With client approval, I use tools like Cursor, GitHub Copilot, ChatGPT, Claude, and Figma AI to speed up development, explore designs, review code, and reduce repetitive work. These tools help me move faster, but final decisions, quality checks, UX thinking, and delivery are always handled carefully by me and my team. A quick snapshot: - 10+ AI-powered application projects - 30+ MVPs built for startups - 30+ SaaS redesign and revamp projects - 100+ frontend and fullstack web projects delivered - 75+ UI/UX projects designed I lead a team of 14 specialists, including designers, frontend developers, fullstack developers, a backend developer, and QA. When your project needs more than one skill set, the right people are already in place. Types of projects I take on: AI-powered web applications and SaaS tools, AI chatbots, assistants, and automation, SaaS platforms and dashboards, admin panels and CRM systems, MVP builds for early-stage startups, product redesigns and frontend revamps, complex workflow and data-heavy web apps, and Figma to React or Next.js implementation. What clients value most: clear communication, honest timelines, structured delivery, and a partner who genuinely cares about the outcome. Tell me what you are building. I will tell you honestly if I am the right fit and how I would approach it.

Hi! I'm a full-stack developer who ended up specializing in a weirdly specific niche: taking things that almost work – a rough AI idea, a half-finished MVP, someone's vibe-coded weekend project – and turning them into something a real business can actually run on. I take on projects at any stage – from a blank page and an idea, to an existing codebase that needs new hands on it. I've been building software professionally for years, and the work that gets me genuinely excited right now is at the intersection of AI and practical business systems: agents that quietly take hours of manual work off someone's plate, dashboards that finally show a founder what's actually happening in their business, and MVPs that go from "idea on a whiteboard" to "thing customers are using" faster than most teams think is possible. ☑️A bit about how I got here I started out doing classic full-stack work – websites, web apps, the usual. Somewhere along the way I noticed a pattern: the most interesting projects weren't "build me a website," they were "we have this process that's eating 10 hours a week, can you make it disappear" or "we tried to build this ourselves with AI tools and it's held together with tape, can you fix it." That's where I've stayed ever since. ☑️What I actually do → AI agents & automation – I build agents that handle real work: customer support triage, report generation, data entry, internal admin. Not chatbot demos – things that replace hours of someone's week, every week. → Custom business systems – CRMs, internal dashboards, workflow tools built around how your team actually works, not around a template you have to bend your process to fit. → SaaS MVPs – if you have an idea and need to see it as a real, clickable product fast, this is probably my favorite type of project. Weeks, not months. → Rescuing stuck projects – this might be the thing I'm most known for at this point. Half-finished builds, AI-generated ("vibe-coded") apps that worked in a demo and fell apart with real users, code from a developer who disappeared mid-project. I go in, figure out what's actually salvageable, and get it to a stable, shippable state – almost always without needing a full rebuild. → Web & mobile development – still very much in my toolkit when that's what the project actually needs. ☑️How I work I don't start typing code the moment a job is posted. I ask questions first – sometimes annoyingly many of them – because building the wrong thing fast is worse than spending an extra hour making sure we're building the right thing. Once we're aligned, I move quickly, communicate proactively (you'll hear from me before you have to ask "any update?"), and I'm honest early if something in the original plan doesn't make sense anymore. If you're not sure exactly what you need – just a business problem and no spec – that's a completely normal place to start a conversation with me from. ☑️A few results from recent projects ·Rebuilt a client's internal CRM around their actual workflow → 35% increase in operational capacity ·Automated order syncing for a manufacturing client → 8–12 hours saved per week ·Took over a 500-page Figma design that needed real engineering behind it → delivered a working, production-ready MVP on schedule ·Picked up a stalled, partially AI-generated MVP that broke under real traffic → stabilized it into a product the client could confidently launch ☑️When it makes sense to reach out · You have a manual process eating your team's time and suspect AI could kill it · You need a CRM, dashboard, or internal tool that fits your actual workflow, not a generic template · You started building something yourself (with AI tools or otherwise) and it's not quite production-ready · You have an idea and want to see a real MVP fast, not a six-month roadmap · You just want a second opinion before committing budget to a build – happy to do a quick, honest audit first Send me a message with what you're working on. Even if it's half-formed, that's a fine place to start.

I'm a full-stack .NET developer with 11 years of experience based in Los Angeles. I'm a true full-stack developer, so I can work equally well on both front and back ends. I have experience in building applications from start to end, so I can take care of building almost any project, then supporting it for the long term. Here are some highlights from my background: - My tech stack is .NET, .NET Core, C#, SQL, Entity Framework, HTML, CSS, JavaScript, and Angular. - Experience with Azure and AWS. I'm especially good with Azure. I can setup Azure resources such as App Services, Function Apps, Azure SQL Databases, Storage Accounts, Key Vaults, Azure DevOps source control, deployment pipelines, etc. - Experience in working on large SaaS applications in healthcare, manufacturing, retail, human resources, and legal industries. - Experience in developing MVPs from start to end. - I write clean and understandable code with well defined architecture using best practices for software security. - Experience in SaaS and multi-tenant applications. - Great work ethics and honesty. If I don't know something, I'll tell you. If I messed up something, I'll tell you. My Certifications: - Microsoft Certified: Azure Developer Associate - Microsoft Certified: Azure AI Engineer Associate Also, I have a team of full-stack software developers. Building and supporting an application for a successful startup usually requires more than one developer. Building an application is like building a house. It usually requires a crew to complete. My team can join your project and help with building it, then support and enhance it in the future.
