MIKO CAÑARES — FULL-STACK + AI + AUTOMATION ENGINEER
I build production software systems that automate complex business workflows.
Full-stack development, AI and RAG systems, workflow automation, and system integrations — built into reliable production software, from frontend to backend.

01 — WHAT I BUILD
Three ways I help teams ship.
Full-Stack SaaS Development
Complete web applications — frontend to backend, database, auth, payments, and deployment.
NEXT.JS · REACT · PYTHON · LARAVEL · POSTGRESQL
AI & RAG Development
AI applications grounded in your data — retrieval, structured outputs, custom workflows.
OPENAI · EMBEDDINGS · PGVECTOR · RAG
Business Automation & Integrations
CRMs, documents, payments, and communication tools connected into one reliable layer.
N8N · WEBHOOKS · REST APIS · SUPABASE
Build
A new SaaS product, internal tool, booking platform, dashboard, or business application.
Add AI
AI chat, RAG, document intelligence, structured outputs, or AI-powered workflows.
Automate
APIs, CRMs, documents, payments, email, scheduling, and internal systems — connected.
Improve
Bugs fixed, performance improved, features added, reliability strengthened.
Test
APIs, workflows, access controls, integrations, and production behavior — validated.
02 — AUTOMATION BACKBONE
I don't just build n8n workflows. I build automation systems.
For a LegalTech firm (NDA), I built both the system that finds the customers and the system that sells and delivers to them — 42 production workflows on one self-hosted n8n backbone. Hover the subsystems, then open the Document Factory.
42 PRODUCTION WORKFLOWS · ONE BACKBONE
03 — SYSTEMS IN PRODUCTION · AI / RAG
READMINDME
Knowledge-grounded AI platform.
The assistant searches its own knowledge base before it answers — retrieval first, generation second, structured output always. Watch a question become a grounded answer.
FASTAPI · POSTGRESQL · PGVECTOR · OPENAI

ATLAS NHD
Statutory hazard disclosure, automated end to end.
Raw state and federal geodata becomes a legally-formatted disclosure report — parcel in, PDF out, with correctness as the product.
FASTAPI · POSTGIS · GEOSERVER · NEXT.JS

Not just automation. Engineering.
Idempotency
Search-then-insert and reuse-or-create patterns prevent duplicate records, events, folders, and resources.
Retries
Retry-on-fail with backoff for API failures and rate limits.
Error Handling
IF-gated branches and dedicated error responses keep failures explicit and manageable.
Pagination / Chunking
Large API datasets are ingested in bounded pages, so no single run can blow up.
AI Extraction
Gemini turns raw documents into structured, validated records before they touch the database.
05 — INTEGRATIONS
Your tools, connected.
Every system here comes from a shipped project — connected, tested, and running in production.
YOUR SYSTEM
+ DOCUMENSO · MAPBOX · CLERK · GOOGLE DRIVE · VOIP.MS · REST APIS
06 — RELIABILITY
Built to work. Built to survive.
I approach software with a development and QA mindset — building the feature, validating the behavior, handling failures, and thinking about what happens after deployment.
FULL-STACK DEVELOPMENT
Frontend, backend, APIs, and databases — built as one coherent system.
AI / AUTOMATION
RAG pipelines, structured AI outputs, and n8n orchestration in production.
QA / RELIABILITY
An enterprise QA background (ERP application testing at DXC Technology) applied to every build.
07 — HOW I WORK
One owner, end to end.
The same person who designs the system builds it, tests it, and ships it.
- 01
Understand
Clarify the problem, the users, and what done means.
- 02
Design
Map the system: data, APIs, integrations, edge cases.
- 03
Build
Ship in small, reviewable increments.
- 04
Integrate
Connect the tools and services your business already runs on.
- 05
Test
Validate behavior, access, and failure paths before release.
- 06
Deploy
Production configuration, monitoring, and rollout.
- 07
Improve
Measure, fix, and extend once real usage arrives.
