I build voice AI agents, GoHighLevel automations, and AI integrations that plug into the systems companies already run. 57 projects, 4,800+ hours on Upwork, 100% Job Success, Top Rated Plus. Most of my work falls into four buckets. VOICE AI AGENTS Inbound and outbound call agents that qualify leads, book appointments, and hand off to a human cleanly. LiveKit with SIP trunking for self-hosted setups, or Vapi and Retell where speed to launch matters more than control. Wired into your CRM so calls become records, not recordings. AI INTEGRATION AND AGENTIC SYSTEMS Connecting LLMs to your existing stack: retrieval over your own documents, tool-calling agents that take real actions, and pipelines that hold up under production traffic. Model-agnostic, building on OpenAI, Claude, and open-weight models depending on cost and latency requirements. GOHIGHLEVEL AND WORKFLOW AUTOMATION GHL sub-account builds, pipelines, funnels, and custom API work that goes past what the native tools handle. n8n and Make for everything else, including the multi-system automations that break in ordinary no-code tools. FULL-STACK PRODUCT DEVELOPMENT Next.js, Node.js, TypeScript, Python and FastAPI, PostgreSQL and Supabase. Custom dashboards, admin panels, internal CRMs, auth systems, third-party API integrations, and deployment on AWS, Vercel, and Supabase. Clients across the US, UK, and the Nordics. I take work from architecture through launch, and I'm comfortable either running a build solo or plugging into an existing engineering team.

Need a full-stack developer who can own your product end-to-end frontend, backend, and everything in between and make sure it holds up under real users, from payments and permissions to third-party integrations? That's usually the point where a product needs someone who can handle the whole stack, not just another quick fix. I help startups and growing businesses turn product ideas into SaaS platforms, mobile apps, and business systems that support real users, payments, reporting, and day-to-day operations. Over 8+ years, I've taken products from MVP to production across real estate, marketplaces, booking, fintech, wellness, e-commerce, and internal business tools + WordPress automation build for an MVP that ran 198 hours over a 5-month engagement, and React Native apps where I isolated and fixed recurring crash bugs post-launch. Clients consistently note that I deliver clean, well-tested work and communicate clearly throughout. That's the stage I specialize in bringing architecture and structure to a product before technical debt slows you down. What I build SaaS platforms & startup MVPs React Native mobile apps (iOS & Android) Marketplace & booking platforms Subscription & payment-based products (Stripe, payment gateways) Admin dashboards & internal business systems API-driven applications & backend systems (REST, GraphQL, webhooks) Wix and Wix Studio websites, including CMS, eCommerce, bookings, memberships and custom functionality Stack: React.js, Next.js, TypeScript, Node.js, NestJS, Express.js, PostgreSQL, MongoDB, Supabase, React Native, AWS, Wix Studio, Velo by Wix, Wix CMS, Wix eCommerce Firebase, Vercel I focus on long-term maintainability over quick patches, deliver structured and documented code, and think about the product as a whole rather than one ticket at a time because the fastest fix now is often the thing that breaks in six months. If you're building a SaaS platform, mobile app, or business system and want a developer who thinks about product as much as code, I'd be glad to talk through your project book a 30-min consultation below or send me a message.

I help SaaS founders move from "idea" to revenue-generating product in weeks, not quarters. For 10+ years, I've built full-stack systems for startups and scaling companies. The last 5 years? AI-first development—taking the latest LLM breakthroughs and turning them into products that actually work. What I Deliver AI SaaS Products From concept to launch-ready: multi-tenant SaaS platforms with AI built-in. Chatbots with memory. Agents that use tools. RAG systems that reason over your data. Not toys—production systems handling real business logic. Support Automation at Scale A recent client was burning $12K/month on support volume. 6 weeks later, their RAG agent handles 73% of tickets autonomously. Margin-positive from day one. Full-Stack Architecture Scalable backends (Python/Node), pixel-perfect frontends (React/Next), integrations that work, infrastructure that doesn't break at 3 am. Clean, modular code built for growth. 🏆 My Track Record 10+ years building production systems 100% Job Success + $50K+ earned on Upwork Senior engineer across startups, agencies, and enterprise ⚡ Tech Stack Python · FastAPI · Node.js · React · Next.js · LangChain · Claude/OpenAI APIs · PostgreSQL · Docker · AWS · n8n 💬 Let's Talk Serious about your SaaS?

I design and build production-grade software for Fortune 500 enterprises and venture-backed startups from blank page to deployed. Multi-tenant SaaS, AI-powered products, and the developer tools infrastructure companies run on. 15+ years of Hands on Experience. WHY LONG-TERM WORKS BETTER Handing a codebase to a new contractor every quarter is how products rot. Context gets lost, architecture drifts, and each new person rebuilds instead of extends. When I stay, decisions compound. I know why the schema looks like that, which shortcut we took under deadline, and what breaks if you change it. DESIGN AND ENGINEERING, ONE PERSON Most teams hire a designer, then a developer, then spend three weeks translating between them. I do both, which removes that gap. I run discovery, map user flows, design in Figma, build the design system, then implement it myself in React and Next.js. Nothing is lost in handoff because there is no handoff. Nothing gets designed that can't be built. For founders without a design team, you get from idea to a real product without hiring twice. For teams that already have designers, you get someone who implements their work to spec instead of approximating it. I design for outcomes, not for dribbble onboarding flows that finish, pricing pages that convert, dashboards people can read under pressure. WHERE I USUALLY COME IN → An idea and no designs yet — discovery through wireframes and UI into a working product. → An MVP from scratch — scoped and scalable rather than overbuilt. → Scaling a product with traction — it works, but architecture is now the constraint. → Rescuing an unstable platform — the previous team left and it breaks in production. → A redesign or modernization — it works, but looks a decade old and converts like it. → Adding AI — RAG, agents, workflows, ai automations or LLM features integrated without destabilizing what works. Past Experiences: One of the largest Web3 node infrastructure providers in the world developer-facing product surfaces used daily by thousands of engineers building on-chain. A venture-backed cloud deployment platform product interface, Frontend App and marketing site, Docs and Guides etc designed and built end to end. A real estate analytics platform for multifamily operators data-heavy dashboards where the hard problem was hierarchy, not decoration. An enterprise smart-stadium platform large-scale venue operations frontend under real reliability constraints. WHAT I DESIGN AND ARCHITECT Product discovery, user flows, wireframes through high-fidelity UI. Design systems that stay consistent past the first release instead of fragmenting into forty button variants. Multi-tenant SaaS with real tenant isolation. Data models that survive scale. RAG pipelines that return grounded answers instead of confident nonsense. Cloud infrastructure sized to your stage and budget. Observability before the incident, not after it. HOW I WORK I'm Founder and CTO of StellarStack, so I've lived with my own architecture decisions for years, not weeks. I start with the business goal, not the ticket what you're measuring, your real constraints, and what this system looks like in eighteen months. That produces a plan with scope, milestones and rollout, instead of a stream of commits. I build it so your team could own it: typed end to end, documented, no dependency on me. Then I usually stay anyway, because most clients would rather keep shipping than manage a handover. If you need more capacity than one person, my team at StellarStack scales up around the work. I'll also tell you when the thing you asked for isn't the thing you need. If a two-week feature won't move your metric, I'd rather say so in week one.
