Home / Hire a developer / AI chatbot or AI assistant

Need a developer to build your AI chatbot or assistant?

Jonald Penpillo, an AI developer in the Philippines, builds AI chatbots and assistants that answer from your own documents and data, cite their sources, respect permissions and refuse what is out of scope. He has three such systems in production.

What Jonald can build for you

  • Retrieval-augmented generation over your policies, manuals or catalogue, with citations
  • Permission-aware answers so each user only sees what they are allowed to
  • Tool-calling agents connected to your live systems
  • Guardrails: prompt-injection screening, fact guards, refusals and spend budgets
  • Evaluation sets and a human review loop that improves answers over time

Proof, not promises

Systems already running

Brigada LLM

One chat for internal AI agents. A router (bge-m3 embeddings + qwen3:8b) sends each question to a Policy Agent with permission-aware hybrid retrieval and citations, or a Quality Rubrics Agent. Runs on local models, so policy text never leaves company servers. Evaluated on 90 policy questions and 76 routing cases.

Stack: Python, FastAPI, Ollama, qwen3:8b, bge-m3, pgvector, Supabase

Delai, AI Travel Companion

A travel assistant with 25 live tools (flights, hotels, tours, weather, tides, safety) and retrieval over 217 curated entries in pgvector. Answers stream as cards onto a live map, with guardrails against invented inventory and a live-model evaluation harness. Innovation Award, Top Executive Congress 2025.

Stack: Python, FastAPI, Gemini via OpenRouter, pgvector, Supabase, React

Brigadahub + Range AI

Booking and payments platform for a 30-bay golf driving range, pickleball courts and a kids playground, with a five-step booking flow, live bay availability and PayMongo checkout. Range AI answers guests on the website and Facebook Messenger and takes them from a question to a paid booking; accuracy on real guest messages rose from 55% to 71%.

Stack: React 19, TypeScript, Express 5, Supabase, PayMongo, Python, scikit-learn, Gemini, Messenger API

Frequently asked questions

Can the AI chatbot run without sending our data to an outside provider?

Yes. Brigada LLM runs entirely on local models through Ollama, so company policy text never leaves the company’s servers.

Will the chatbot make things up?

Jonald designs against it: answers are grounded in retrieved sources with citations, fact guards block changed prices or links, and evaluation sets measure accuracy before and after changes.

Do you work with clients outside the Philippines?

Yes. Jonald is based in General Santos City, Philippines, and works remotely with clients worldwide, in English, Filipino or Cebuano.
