🚀 I build AI agents, n8n automations, and full-stack AI SaaS platforms that hold up with real users — and I rescue the ones that broke along the way.
Senior AI Full-Stack Developer | 8 years | $100K+ earned | 56 jobs | 5,600+ hours on Upwork
Right now, I'm scaling an AI-powered SaaS that processes 2M+ leads/month. Over 8 years, I've shipped everything from n8n automations and OpenAI/RAG agents to Stripe billing systems, HealthTech platforms, and React Native apps for clients worldwide.
Here's the difference: most AI demos look great, then fall apart the moment real users, messy data, and edge cases hit. I build automations and products that keep working under that pressure — and I fix the ones that don't.
⚡ What I do best:
• AI Automation & Agents — n8n workflows, AI agents, OpenAI/ChatGPT, LangChain, RAG pipelines, chatbots
• Full-Stack AI SaaS — Next.js, React, Node.js, NestJS, TypeScript, PostgreSQL, multi-tenant, dashboards, admin panels
• API & Integrations — REST APIs, third-party integrations, webhooks, backend LLM routing
• Stripe Payments — subscriptions, payouts, webhooks, billing flows
• Cloud & DevOps — AWS, Vercel, Docker, CI/CD
• Mobile Apps — React Native (iOS & Android)
🛠 Recent wins:
• Built n8n automations and AI-agent workflows that cut manual, repetitive work for clients
• Shipped production AI features with OpenAI + RAG pipelines on AWS Bedrock
• Scaled a B2B SaaS to 2M+ leads/month with distributed Elasticsearch + analytics
• Architected a 3-role HealthTech platform (Doctor / Patient / Hospital Admin) on Next.js + NestJS
• Led a FinTech security incident response and restored production within 72 hours
• Built Stripe-powered billing systems used by real customers every day
💡 Why clients keep coming back:
Clean, typed, maintainable code and clear communication — no jargon, no disappearing acts, no missed deadlines. I use modern AI tooling (Claude Code, Cursor, Codex) to move fast without cutting corners, with every change reviewed by me.
Whether you're automating your operations with n8n and AI agents, building a new AI SaaS from scratch, integrating OpenAI/ChatGPT, or fixing and scaling an existing app — I can own it end-to-end and deliver something your users actually rely on.
📞 Tell me what you're building or automating, and I'll tell you exactly how I'd approach it — no obligation.

I can build the real backend, app, and integrations for when your system outgrows no-code.
A Senior Software Engineer with 6+ years of experience building AI automation and the custom software around it. That combination matters: no-code tools like n8n and Make are perfect until your workflow needs a proper database, a custom API, error handling that actually holds up in production, or a dashboard/app your team can use. That's exactly where most automation freelancers stop — and where I take over.
🏅 Top Rated · 💯 100% Job Success · ⭐ 5-Star Ratings · ✅ $100K+ earned · 5,900+ hours
What I build:
🤖 AI Voice Agents & Chatbots — inbound/outbound voice agents, WhatsApp & web chatbots, lead qualification and customer support that answers instantly and books/qualifies while you sleep (VAPI, Retell, OpenAI, Claude), wired straight into your CRM.
⚙️ AI Automation & Ops Systems — end-to-end workflow automation with n8n, Make, and GoHighLevel: lead capture and follow-up, proposal generation, reporting, and tool-to-tool sync so nothing falls through the cracks.
🚀 GoHighLevel Builds & White-Label (SaaS Mode) — full GHL setup for agencies and service businesses: funnels, pipelines, workflows, calendars, and A2P/email deliverability — plus SaaS-mode white-labeling and reusable snapshots so you can resell it. I connect GHL to AI agents and custom code where it hits its limits.
🧩 Custom AI Software & Internal Tools — when no-code hits its ceiling, I build the real thing: FastAPI/Node backends, custom AI agents, dashboards, and databases (Postgres, Mongo, DynamoDB) tailored to how your business actually runs.
📱 Full-Stack & Mobile — React Native, React/Next.js, Node.js, Python/Django, plus AWS & GCP deployment and CI/CD. I can wrap your automation in a proper app or dashboard, not just a Zapier zap.
Why clients hire me: they're tired of broken automations that fail silently, demos that impress but solve nothing in production, and freelancers who can't code their way past a no-code wall. Every system I deliver comes with clean architecture, documentation, and SOPs so your team can maintain and scale it without me.
If you want AI and automation that actually holds up in production — and an engineer who can build whatever the no-code tools can't — let's talk.

I’m a Full Stack Developer, SaaS Developer, MVP Developer and AI Integration Developer focused on building production-ready web applications, SaaS platforms, MVP products, AI-powered applications and scalable internal tools.
My work sits at the intersection of Full Stack Development, SaaS Development, MVP Development, AI Integration, Backend Development and product architecture. I help founders, startups and growing teams turn early product ideas into real software products, from validation-stage prototypes to launch-ready SaaS platforms, dashboards, admin panels, customer portals, workflow tools and AI-enabled applications.
As a Full Stack Developer, I work across frontend, backend, databases, APIs and product logic. My frontend work is usually React and Next.js based, while my backend work often involves Node.js, Python, FastAPI, REST APIs, authentication systems, database architecture, third-party integrations and scalable backend services.
As a SaaS Developer, I focus on building SaaS products that can support real users, real workflows and long-term product growth. This includes multi-role dashboards, user permissions, authentication, subscription-ready flows, payment integrations, admin panels, reporting systems, customer portals, API integrations and operational tools that teams can confidently use after launch.
As an MVP Developer, I help founders and product teams move quickly without building throwaway prototypes. I focus on the core user journey first, then design the technical foundation around what the product needs to become. My MVP Development work helps teams launch faster while keeping the product maintainable, scalable and easier to improve after the first release.
As an AI Integration Developer, I build AI-powered features inside real products, not isolated demos. My AI Integration work can include AI agents, AI workflows, LLM-based features, automation logic, data processing, AI-powered dashboards, chatbot features, recommendation systems and backend systems that connect AI functionality with real business workflows.
As a Backend Developer, I design and build the technical foundation behind SaaS platforms, MVP products and AI-powered applications. This includes APIs, database models, authentication, authorization, background jobs, integrations, backend workflows and scalable service logic that keeps products reliable as they grow.
Clients typically work with me when they need:
* a Full Stack Developer who can own frontend, backend, databases and APIs
* a SaaS Developer who understands product architecture and long-term scalability
* an MVP Developer who can turn an idea into a launch-ready product
* an AI Integration Developer who can add practical AI features into real software
* a Backend Developer experienced with Node.js, Python, FastAPI and REST APIs
* a Full Stack Developer for SaaS MVPs, dashboards and internal tools
* a SaaS Developer for authentication, permissions, payment flows and admin panels

* AI Integration support for automation, AI agents, AI workflows and LLM-based features
* React and Next.js web applications connected to stable backend systems
* scalable API-driven products built for real users and future growth
* internal tools, CRMs, portals, dashboards and operational platforms
* backend-connected SaaS platforms with clean database architecture
* product modernization, technical rebuilds and architecture improvements
A large part of my work as a Full Stack Developer, SaaS Developer, MVP Developer and AI Integration Developer focuses on:
* Full Stack Development for SaaS platforms and web applications
* SaaS Development from MVP to scalable product architecture
* MVP Development for founders, startups and early-stage products
* AI Integration for SaaS products, dashboards and automation workflows
* React and Next.js frontend development
* Node.js and Python backend development
* FastAPI, REST APIs and third-party API integrations
* database architecture with PostgreSQL, MongoDB and Redis
* authentication, authorization and role-based access
* dashboards, admin panels, CRMs and customer portals
* workflow automation and AI-enabled business logic
* backend systems for AI-powered applications
* internal tools and operational platforms
* scalable product architecture for growing teams
* API-first software products built for real business use
My Full Stack Developer work is focused on making sure the frontend, backend, database, APIs and integrations work together as one stable product. My SaaS Developer work is focused on building products that can support real users, repeated workflows and long-term product growth. My MVP Developer work is focused on helping teams launch the right first version quickly and intelligently.

* Zero ambiguity → Clear scope. Clear architecture. Clear outcomes. You’ll know exactly what we’re building, why we’re building it, and what it will cost.
* Built for scale from day one → I don’t build “just working” apps. I design systems that handle growth, traffic spikes, and real users without breaking.
* Speed without chaos → Fast execution, clean code, structured milestones. Momentum matters - but so does maintainability.
* Full product ownership → From idea validation to deployment (Flutter, Firebase, backend, infra) - I handle the entire lifecycle. You won’t need five different freelancers.
* Engineering mindset, business focus → I don’t just write code. I solve business problems with technology.
Let’s connect and bring your product vision to life.
