RAINER LACANLALE
Full-Stack Developer · AI & Agentic Systems
I design and build complete digital products — from the website a customer sees to the backend behind it and the AI that does the work inside it.

Who you are hiring
I am a full-stack developer who builds the whole product, not one slice of it.
That means the part people see — the site or the app — and the part they do not: the database, the accounts, the payments, the admin screens your own staff use. I design it as well as build it, so the way it looks and the way it works are decided together rather than handed between two people.
On top of that I build AI agents. An agent is software that reads your real data and then takes an action on it — answering a customer with the actual stock level, turning a written brief into a schedule, updating an order — instead of just producing text. Most of my work starts the same way: someone is doing something by hand every day that software should be doing.
Capabilities
What I build
Two kinds of work, sold to two kinds of buyer: the thing your customers use, and the thing that runs the business behind it. Most projects need some of both.
Track 01
Websites & apps
The public-facing side of the business — the things a customer actually touches, built to load fast and be edited without a developer.
- Landing pages
- E-commerce
- Portfolio & brand sites
- Full-stack web apps
- Mobile apps
Track 02
AI agentic systems
The operational side — software that does the repetitive work a person is currently doing by hand, grounded in your live business data.
- Agentic operating systems
- Support & operations agents
- Workflow automation
- Integration & data plumbing

Shipped, open source, and it remembers what matters — without a single line of your data leaving the machine.
An AI assistant that runs on your own computer instead of in someone else’s cloud. It is for people who want the usefulness of an AI assistant without handing their files, messages and API keys to a third party — so everything stays on the machine. I designed and built it, and it is open source, so the code and the decisions behind it can be read rather than taken on trust.

Nesko
Founder & Lead Developer · March 2025 – Present
Live on Google Play, and running on an eighth of the database bill it started with.
A phone app for people who know what they have to do but not when to do it. You describe the week in your own words and it lays out a real schedule, with an assistant inside it that can create the tasks, look things up, draft a document and read through your email for what you missed. I founded it and built the whole thing — app, backend and the AI layer — and it is live on Google Play.
