Available for software & ML roles
Hi, I'm Neil Brags Guzman. I'm a Full Stack and AI engineer, I do things.
Based in Manila, Philippines.
Currently working on
Chatbot LLM
A terminal chatbot in Python that sends prompts to Gemini 3.1 Flash-Lite and logs the conversation to a JSON file, which is meant to become its memory. Very early: it takes a prompt, saves it and sends it, and that's about it so far. I'm writing it without a framework to learn how the pieces actually fit.

“The site and the system were built in 3 days?! It works flawlessly, and this is hands down the fastest dev I've ever seen.”
JGC, client for GN Bags A full shop and back office for a small bag seller in Isabela, delivered in three days: the storefront with guest checkout, GCash and BDO payments with screenshot proof, an Android app the owner uses to manage bags, photos, orders and payment checks, and Telegram alerts for every new order.
Experience
Owner
Ori
2024 – Present- Run Ori, a side business that builds websites and small systems for startups, handling each project from the first client call through delivery.
- Built ori.brags.dev in Next.js and TypeScript: clients describe the site or system they need, see pricing converted to their own currency, and submit a build request that is delivered to me by transactional email.

Jun 2025 – Jan 2026- Wrote Python scripts with pandas and NumPy to detect corrupted records and correct mislabeled examples in LLM training datasets.
- Fine-tuned local models on the cleaned data using Hugging Face Transformers and MLX, running inference through Ollama, to check that the cleaning improved output quality.
- Scored model outputs against defined evaluation rubrics alongside other AI engineers.
Full Stack Engineer
The Async Studio
Apr 2025 – Jan 2026- Maintained and extended production client apps in TypeScript, shipping features across Next.js frontends and Node.js/Express REST APIs.
- Worked across MongoDB, PostgreSQL, MySQL, and Supabase depending on the client, using Prisma for schema and queries on the SQL databases.
- Implemented authentication with NextAuth (OAuth providers) and JWT-based sessions for the Express APIs.
- Deployed frontends to Vercel and backend services to AWS, packaging services with Docker.
- Built a customer support chatbot for an e-commerce site as a Python service (FastAPI and Flask) calling the OpenAI API, which the Node.js backend called for chat responses.
- Turned client requirements into working prototypes of websites and internal systems, including inventory systems, so clients could review them before full development started.
iOS & Full Stack Developer
The Async Studio
Apr 2025 – Jan 2026- Moved from the full stack team to focus on mobile, building client apps in SwiftUI and in React Native with Expo.
- Built the mobile side of client apps from Figma UI design through implementation, connected to the team's Node.js APIs.
