I build AI systems that actually do things.

I designed and built a custom CRM and business management platform for a robotics and technology school. The system centralizes customers, students, groups, payments, salaries, rent, and operational expenses.

Instead of functioning only as a contact database, the CRM acts as a business control panel. It automatically calculates revenue, operating expenses, teacher salaries, rental costs, profit, and profitability by individual student group.

Group-level economics makes it possible to identify which classes are profitable and which require changes in occupancy, pricing, scheduling, or costs — turning fragmented operational data into a single interface for day-to-day business decisions.

AmoTg — amoCRM ↔ Telegram integration

Small sales teams often talk to clients from personal Telegram accounts, so those conversations never reach the CRM — and standard connectors only work with bots. I built AmoTg: it connects a real Telegram account to amoCRM through the MTProto protocol and the amoCRM Chats API. Every private conversation appears in the deal card, and managers can reply or write first without leaving the CRM.

It started as an internal tool for a school and became a product: a sales landing page with lead capture, a portable deployment kit, and a first installation for an external client on their own server — hardened, backed up and accepted scenario by scenario. A multi-tenant version with an amoCRM widget for the amoMarket marketplace is in progress.

The hard part is reliability. Telegram delivers each event only once, so when the CRM is unavailable a message goes to an outbox and is retried with backoff instead of being lost. Incoming webhooks are signature-checked, because the endpoint can send messages from a personal account.

The agent drafts. A human presses Send.

Margo — SMM and inbox agent

Margo is a persistent AI agent that runs a school's content workflow through Telegram. I send an idea as text or a voice note; she writes the post in my style, generates images and carousels, and prepares versions for LinkedIn, Instagram, Telegram, TikTok and X. Nothing is published without explicit approval of each post.

Her second job is the admin inbox. When a parent writes to the school's Telegram account, a small daemon waits for the conversation to settle, wakes the agent through a signed webhook, and she leaves a reply as a Telegram draft that syncs to my phone.

The approval rule is enforced in code, not in the prompt: the agent's Telegram toolset has no send function at all. Voice notes are transcribed locally, and the agent runs in its own isolated container with its own credentials.

Automating the customer journey from first message to payment.

Currently in development

I am developing an AI-powered administrative automation system for a robotics and technology school. The goal is to remove repetitive administrative work throughout the customer journey.

The system handles common customer questions, guides prospective customers through the enrollment funnel, helps them reach trial lesson registration, sends payment reminders, collects payment confirmations, and organizes the relevant documents for accounting.

The objective is not to create another chatbot. It is an end-to-end operational workflow where AI can perform actions across the business process while escalating situations to a human when necessary.

A school website where no enquiry gets lost.

Public website, enrollment form, student questionnaire

I built and launched the public website for a robotics and technology school: a fast static landing page with an enrollment form, served from my own infrastructure. A submitted form reaches a small backend that notifies the team in Telegram within seconds, and the visitor lands on a dedicated thank-you page that works as a URL-based conversion goal for ad and analytics platforms.

A separate questionnaire collects student details before the first lesson. Every submission is written to disk before any notification is sent, so nothing is lost if Telegram is unavailable; each gets a readable ID, and spam is filtered with a honeypot field and a per-IP rate limit.

The bot token never reaches the browser, and the recipients are allowlisted in the backend code, so even a modified config cannot redirect applications elsewhere.

One agent for everyday operations.

I deployed a persistent AI assistant that helps coordinate recurring tasks in everyday life. Instead of using separate tools for every small workflow, the agent provides one conversational layer between me and external services and information.

The project focuses on an important part of agentic systems: moving from isolated prompts to persistent agents capable of tracking context and working with external tools.

Revision as a game, not a test.

Kahoot-style live classroom quiz

For my AI course I wanted students to review each lesson through play. I built a real-time quiz: the host screen shows a PIN and a QR code, students join from any device, answer against the clock, and finish with a leaderboard and a podium.

Designed from both the teacher's and the student's side: points depend on speed, answer options are shuffled, and every game is saved on the server with a results page and CSV export, so the teacher can review how each student did. It ran on the course server through a secure tunnel, without opening inbound ports.

I designed and operated the technical infrastructure for an AI application development course with 18 students. I provisioned and configured the server and created an isolated containerized environment for every participant, where they could build and deploy applications without interfering with anyone else's work.

I also taught students how to access a remote server, work inside their environment, deploy applications, and operate their own services. The objective was to move beyond local prototypes and teach how software actually reaches a running server.

I couldn't find the learning tool I wanted, so I built it.

Falar — Personal European Portuguese learning app

The project started from a practical problem: many mainstream language-learning products focus primarily on Brazilian Portuguese, while I needed a learning experience closer to the language used around me in Portugal.

I created a dedicated application around my own learning workflow and continue iterating on it through real daily usage. The project combines my experience in education, product design, software development, and AI-assisted learning.

Owning the infrastructure behind the tools I use.

Most of the systems on this page run on a server I operate myself: around twenty containers — four AI agents, the school CRM, websites, integrations and analytics — behind a single reverse proxy with automatic TLS and security headers.

Each agent gets its own container, storage, credentials and bot, with memory limits per service. Data is backed up nightly with encryption to a separate volume with daily and weekly retention; SSH is key-only and brute-force attempts are banned automatically.

I also run private network services for my family: a VPN with client isolation and a two-server private network that routes traffic by destination.
