I build complete web applications and complex automation systems — and I specialize in combining both. Whether you need a custom SaaS product, an internal dashboard wired into your operations, or an AI-powered platform that runs itself, I can design the database, build the backend, ship the frontend, and automate everything around it.
Full-Stack Web Development
I build production-grade web applications end-to-end:
- Frontend: Next.js (App Router), React, TypeScript, Tailwind CSS, shadcn/ui
- Backend: Node.js, Deno, serverless functions, REST and GraphQL APIs, webhook infrastructure
- Databases: PostgreSQL, Supabase, MySQL, MongoDB, Redis — schema design, migrations, row-level security, performance tuning
- Auth & Payments: Supabase Auth, Clerk, NextAuth, Stripe, JWT, PKCE flows
- Infrastructure: Vercel, Railway, Docker, CI/CD pipelines
- AI-Native Apps: streaming chat UIs, voice agents (telephony + TTS/STT), RAG pipelines, vector databases, custom AI-powered SaaS
Automation & AI Integration
I'm an n8n & Make Level 5 certified expert and solution partner with 3+ years of experience, 95+ clients, and hundreds of automations delivered. I pride myself on building complex automations with different functions and modules that work flawlessly, connecting virtually any platform with another for seamless integration.
I build complete end-to-end AI automations for video creation, script generation, presentation generation, voice generation, article creation, social media auto-posting, and reply handling. My video pipelines generate AI images (or pull from Google search), produce voiceovers via ElevenLabs or similar APIs, and assemble full videos perfectly synced to the visuals.
I work across the leading AI creative stack — Nano Banana, Sora, Kling, Infinite Talk, Veo 3, MidJourney, Imagen
— through providers like WaveSpeed, Kie, Fal, Replicate, OpenAI, and Google. These pipelines save thousands of hours and scale content output as far as you need.
As a certified automation specialist, I'm extremely proficient with inline functions, data handling, error handling, and workflow optimization.
Services I Offer:
- Full-Stack Web App Development — dashboards, client portals, internal tools, and custom SaaS products built with Next.js, React, Node.js, and Deno.
- Database Design & Management — PostgreSQL, Supabase, MySQL, MongoDB, Redis — schema design, migrations, RLS, and performance tuning.
- Auth, Payments & Deployment — Supabase Auth, Clerk, NextAuth, Stripe, plus deployment on Vercel, Railway, and Docker with CI/CD.
- Custom Make & n8n Automation — tailored automation systems for businesses of any size.
- CRM Integration & Automation — HubSpot, HighLevel, Monday, ClickUp, Airtable.
- Custom API Integration — deep API and auth expertise; if your app isn't on Make , I'll integrate it.
- AI-Powered Solutions — OpenAI, Claude, Gemini, HeyGen, ElevenLabs, Pictory — from chatbots to data analysis.
- Custom HTTP API Calls — for apps without native integrations.
- Bug Fixing & Optimization — troubleshooting, error handling, and hardening for reliability.

With hundreds of successful API integrations, full-stack builds, and experience across CRMs, AI platforms, and custom app development, I bring a deep understanding of how to design, build, and automate complete systems for any business.
