Full-Stack Developer & AI Automation Engineer
Hi, I'm
Angelo Zuniga.
5 years building production-ready web apps and the AI automation systems that power them. On the dev side: full-stack products — CRMs, marketplaces, payment platforms — owned end-to-end from schema to deployment. On the automation side: n8n and Make workflows powered by AI that replace manual work — lead scoring, CRM routing, outreach sequences, data enrichment, and more.

/what I build
Full-Stack Web Development
I build complete, production-ready web products — not just the frontend. From database schema and API design to authentication, payments, and deployment. Clients hand me a problem and get back a working product.
- Next.js full-stack applications with TypeScript
- Database design with PostgreSQL, Supabase, and Prisma
- Payment integration via Stripe — subscriptions, one-time, and metered
- Role-based auth with NextAuth across multiple user types
- Admin dashboards, CRM tools, and customer portals
- E-commerce, directory, and marketplace platforms
- Redis caching, Leaflet.js maps, and file storage
- SEO-optimized public pages and structured metadata
AI Automation Engineering
I build workflow automation systems that use AI to replace repetitive human tasks. Lead scoring, CRM routing, outreach triggers, data enrichment — wired together in n8n or Make and powered by OpenAI or Gemini.
- AI lead scoring using Gemini to classify intent and route prospects
- CRM pipeline automation — stage routing, follow-up triggers, alerts
- Outreach sequences triggered by lead score thresholds
- Contact enrichment workflows filling gaps automatically
- RAG-powered AI apps grounded in private knowledge bases
- n8n and Make visual workflows — no custom backend required
- Slack, email, and webhook notification systems
- pgvector semantic search with OpenAI embeddings

Lead Scoring & Qualification
n8n · Gemini API · WebhooksAI scores inbound leads by intent signals, job title, company size, and message content — routing hot prospects to the right pipeline stage automatically, no manual triage.
CRM & Pipeline Automation
n8n · Make · SupabaseAutomated stage routing, follow-up sequence triggers, and real-time Slack or email alerts when a high-intent lead enters the pipeline — the CRM manages itself.
Outreach Sequences
n8n · Make · Email APIsScore-triggered email and messaging flows that fire the moment a lead qualifies — zero manual handoff between inquiry and first touchpoint.
Contact Data Enrichment
n8n · Enrichment APIsWorkflows that automatically fill in missing contact fields — company name, industry, LinkedIn profile — so your CRM stays clean without anyone doing it manually.
RAG-Powered AI Applications
OpenAI · pgvector · Supabase · Next.jsConversational apps grounded in a private knowledge base using embeddings, semantic search, and OpenAI or Gemini — answers come from your data, not generic training.
Visual Workflow Systems
n8n · Make · ZapierEnd-to-end automation built visually in n8n and Make — no custom backend required, fully modifiable without touching code, easy to hand off to any team.

/how I work
Web & Full-Stack Projects
Discovery
We start with the problem, not the feature list. I map your users, workflows, and what success actually looks like — scope gets locked before a single line of code is written.
Design
Wireframes in Figma, architecture decisions, stack selection. You see exactly what you're getting before the build starts — no surprises, no mid-project pivots.
Build
End-to-end development with regular check-ins. Frontend, backend, database, auth, payments — I own the full stack so nothing slips between layers.
Ship & Hand Off
Deployed, tested, and documented. You get a product that runs in production — and a clean codebase you can maintain and extend without me.
AI Automation Projects
Audit
We map every manual task being done today — lead handling, data entry, follow-ups — and identify exactly where AI can take over. The bottleneck comes first, not the tool.
Map the Flow
Triggers, conditions, AI decisions, actions, and fallbacks — the full workflow is designed on paper before anything is built. Clear input and output at every step.
Build & Connect
Wire up the stack: webhooks, AI scoring via Gemini or OpenAI, CRM routing, enrichment APIs, Slack or email alerts — each piece tested in isolation before connecting.
Test & Hand Off
Real data runs through the system, edge cases get handled, error alerts get set up. You get a workflow that's fully visual, modifiable, and documented — no black boxes.
