Full-Stack & AI Automation Engineer

James Anthony O. Rosales

I build and self-host production systems on Laravel, Vue, n8n, and RAG that take repetitive work off your team.

Recent BSIT graduate, Magna Cum Laude. I shipped a self-hosted AI customer operations platform, helped build CAFE for CHED Region V, and deploy Laravel/Vue systems that automate real operational work.

Open to work

AI automation, full-stack development, or operations support roles. Quick to train.

How I can help

Three ways I work with teams

Most of my work sits where automation meets the web. Here is how that maps to what you might need.

AI & Workflow Automation

I take repetitive work off your team — lead capture, email triage, and knowledge-grounded replies — with a human approving every send.

  • n8n workflows
  • RAG / hybrid search
  • API & webhook integration
  • Lead & email automation

Full-Stack Web Development

I build and ship Laravel + Vue applications, then deploy and maintain them on Linux and Docker so they stay reliable in production.

  • Laravel + Vue / Inertia
  • PostgreSQL / MySQL
  • Docker & DigitalOcean
  • CI/CD & deployment

Operations & Automation Support

I automate the repetitive parts of operations — data cleanup, reporting, and internal dashboards. Open to ops/VA roles and quick to train.

  • Process automation
  • Data cleanup & reporting
  • Internal dashboards
  • Documentation
About

What I Bring

I started in web development, then moved into delivery and infrastructure, and now into AI automation.

Today most of my work lives where automation meets the web: production RAG pipelines, n8n workflows, and the Laravel/Vue systems and Linux servers they run on.

My strongest signal is practical ownership. I have shipped an AI customer operations platform end to end, built a government platform used by 200+ institutions, deployed full-stack apps to production, and handled the networking and data work in between.

Measured, Not Assumed

I validate what I build. My RAG system ships with an evaluation harness that catches quality regressions — retrieval is reported in Recall@k and MRR, not vibes.

Human in the Loop

Automation should remove the busywork, not the judgment. I design flows where a person reviews, edits, and approves before anything goes out.

Built to Be Deployed

I think about the path from browser to server: reverse proxies, storage, access control, backups, and recovery — so a system stays reliable, not just demo-ready.

AI Customer Operations Platform

Full-Stack & AI Automation Engineer / 2026

Removed about 4 hours per day of manual inbox work with a self-hosted RAG and n8n operations platform.

~4 hrs/day saved
100% Recall@5
MRR 0.96
8 active workflows

Context

The platform captures leads, triages inbound email, drafts knowledge-grounded replies, and keeps a human approval step before anything sends.

My Role

I built the Laravel/Vue product, the n8n workflow layer, the Qdrant retrieval pipeline, and the two-server Docker deployment.

Key Decisions

  • Combined dense embeddings and BM25 sparse search with Reciprocal Rank Fusion so exact plan names and prices are not missed.
  • Added cross-encoder reranking through llama.cpp to reorder retrieved chunks by true query relevance.
  • Kept every outbound AI reply behind a human review queue for safer customer operations.

Demo walkthrough

Production Government Platform

CAFE System (CHED RO V)

Sole Developer / Infrastructure Support / Feb - May 2026

Built a live regional Laravel platform used by 200+ Higher Education Institutions across Region V.

200+ HEIs served
Live government platform
SSO integrated

Context

CHED RO V needed a reliable platform to collect institutional forms, gate file uploads, generate certificates, and support regional reporting workflows.

My Role

I owned the production Laravel work, moved file storage to AWS S3, secured API access with Sanctum, integrated OneTouch SSO, and cleaned multi-year enrollment data.

Key Decisions

  • Moved uploaded files away from local disk to reduce production server storage pressure.
  • Protected reporting endpoints with token-based Laravel Sanctum access.
  • Integrated the CHED Central Office API so institutional records could be searched in real time.

Application Tracking System (PCA)

Full Stack Developer / Apr - Nov 2025

Replaced legacy file-based tracking with a deployed applicant tracking system and production Linux setup.

Linux droplet deployed
HTTPS + DNS configured
Daily database backups

Context

PCA Regional Office V needed a centralized way to track applicant projects, proponent details, approvals, notifications, and project locations.

My Role

I provisioned a DigitalOcean droplet, configured LEMP, DNS, SSL, daily backups, SMS notifications, and Leaflet-based geospatial mapping.

Key Decisions

  • Limited server access with SSH keys, UFW rules, and disabled root login.
  • Configured Nginx server blocks, HTTPS redirects, and Let's Encrypt certificates.
  • Added SMS status notifications and map-based project location tracking.

Workforce Operations Platform

Full-Stack Developer (Remote) / Apr - Jun 2026

Delivered a multi-company workforce platform with scoped scheduling, documents, announcements, and real-time events.

Multi-company scoping
Real-time events
20+ PHPUnit tests

Context

Administrators, supervisors, and employees needed one system for shift scheduling, document management, and company-scoped communication.

My Role

I built the Laravel 13 + Vue 3/Inertia application with Action/DTO patterns, PostgreSQL optimization, AWS S3 storage, Redis queues, Horizon, and Reverb.

Key Decisions

  • Centralized shift data to reduce scheduling conflicts across company teams.
  • Used Action/DTO patterns to keep the backend easier to test and maintain.
  • Backed key behavior with 20+ PHPUnit tests before handoff.
