Rodger Arteta / Software engineer
Philippines · Building since 2019I build web and mobile products. Now I’m extending that foundation into full-stack AI systems, agents, and the runtimes that keep them controlled and observable.
01 / Selected work
Real client work and independent experiments.
A look at the interface—and what makes it work.
Client work / Commerce
From first impression to product discovery.
A responsive storefront for a Philippine skincare brand, connecting product stories, customer reviews, and enquiries.
Delivered responsive product sections, Cloudinary media, TikTok Shop review integration, a server-side SMTP contact flow, and production SEO metadata.
Private prototype / Applied AI
Interview practice, in conversation.
A voice and chat prototype exploring streaming responses, conversational interfaces, and the systems that hold a session together.
Built with a Next.js interface, FastAPI backend, WebSocket streaming, and OpenAI integration. PostgreSQL stores durable data; Redis manages session state. Demo available during an interview.
Independent concept / AI + UI
A quieter way to discover skincare.
An independent commerce concept pairing product storytelling with a Gemini-powered routine consultation.
Created responsive commerce interactions, product discovery, cart interactions, and an AI consultation flow. This is a public concept demo, not a client engagement.
02 / An evolving practice
The response is only
one part of the system.
My roadmap connects backend fundamentals, retrieval and evaluation, then controlled agent execution. Nexus is an earlier prototype; the projects below define the next stage of my practice.
Voice, conversational UI, streaming, and session state.
Python and backend fundamentals, evidence-grounded answers, and agent runtime controls.
Voice and chat give people two ways to practice. Streaming responses bring the next part of the conversation into the interface as it arrives.
Design question: how should the interface communicate listening, waiting, and responding?
Next / The build roadmap
A 12-week learning plan toward full-stack agentic AI and harness engineering. These projects are planned; demos and results will follow the work.
Backend foundations
Build a dependable backend to ingest, validate, query, and summarize transaction data.
Python · FastAPI · SQL · Testing
Evidence to publishAPI contracts, architecture decisions, test results, and a reproducible demo.
Retrieval and evaluation
Answer questions from a curated document collection with verifiable citations and measurable retrieval quality.
Retrieval · Citations · Evaluations · Tracing
Evidence to publishA versioned evaluation set, citation checks, and analysis of unsupported answers and failure cases.
Agentic and harness engineering
Build a controlled agent runtime with explicit tool permissions, durable state, approvals, isolation, and observability.
Agent loops · MCP · Approvals · Sandboxing
Evidence to publishState-machine diagrams, a threat model, execution traces, and tests for unsafe or failing paths.
The goal: explain what I built, how I tested it, where it fails, and the trade-offs behind it.
03 / Experience
From logistics workflows to financial products. Building alongside people who care about what ships.

OFFLINE / JAPAN04 / Beyond the screen
Photography is my other practice. I return to Japan with a camera, looking for the streets, weather, and quiet details between destinations.
Different tools. The same habit of paying attention.
