01Proven in production
Proof, not promises.
The strongest work is not a gallery of screens. It is the path from a business constraint to something people can actually use.
01Live SaaS, paying customers
Mensagi, AI customer service on WhatsApp and Instagram
A multi-tenant SaaS that answers the first contact, checks the real calendar and books the appointment. Built and operated with a partner.
- Problem
- Service businesses (barbershops, gyms, clinics) lose bookings after hours, and answering the same WhatsApp and Instagram questions by hand consumes the working day.
- Build
- pnpm and Turborepo monorepo: Next.js on Vercel, an authoritative Fastify API, BullMQ workers, one isolated container per WhatsApp number, Supabase with row level security, Redis, and LLM calls behind a prompt layer.
- Outcome
- In production with around twelve businesses and paying customers in Portugal and Brazil. The AI books into the real calendar, with owner approval where it is wanted and escalation when a conversation needs a person.
02Private client system
Semantic search over support history
A RAG workflow that turns years of solved tickets into usable context during triage.
- Problem
- Resolutions lived inside old Freshservice tickets, so agents repeatedly solved familiar issues from scratch.
- Build
- Freshservice ingestion, Supabase pgvector, embeddings, n8n synchronization, retrieval and agent handoff.
- Outcome
- Past resolutions became available during triage as part of an automation program that reduced manual effort by 60%.
0315+ client deliveries
CRM and ERP integration delivery
Integration work across the less glamorous systems where operations either flow or stop.
- Problem
- Teams retyped information between HubSpot, Pipedrive, Salesforce, SAP and custom systems.
- Build
- Discovery, process mapping, REST APIs, webhooks, n8n, Make and Python services, from scope to handoff.
- Outcome
- Projects across legal, retail, healthcare, real estate and professional services reduced manual effort by 60%.

Small enough to learn. Real enough to fail.
MVPs are separated from mature production work on purpose. They prove a behavior, a market or an operating model, not a finished company.
Live, validatingLive, validating
Orçamentista, quoting for construction and ITED
A platform that takes a Portuguese construction or electrical company from client request to sent proposal, attacking the real bottleneck: waiting for supplier prices. Suppliers reply through a single link, with no account and nothing to install.
What it proved
The platform is live and the pricing engine explains every number back to the rule that produced it, but the central bet, that suppliers actually answer a cold link, is not validated yet. That is the next test, not more features.
03Concepts
Thinking made visible.
These are product explorations, not production claims. Their value is in framing the problem, testing the flow and making a decision easier.
Padel App
A multi-role product concept connecting players, clubs and organizers through schedules, events and balanced matches.
What it proved
One shared product needs radically different priorities for each role.
Daillo
A conversational wellbeing concept that turns a chat into a daily, inspectable supplement routine.
What it proved
AI advice only becomes useful when it resolves into clear actions and history.
04About and method
Somewhere between business and code.
I do not start with the technology. I start with what needs to happen, who is doing it today and where the process breaks.
Alexandre JaquesLisbon, Portugal
Six continuous years at ChatGuru took me from the first Customer Success hire to Director. Alongside that path, I ran IntegraNinja part-time and delivered integration work for clients. That mix of customers, operations, product and engineering is the reason I can translate between a business problem and the system required to solve it.

05Everything led to this
A Oficina.
A live venture where the same method becomes public: understand a real problem, build the system, expose what breaks and teach from production evidence.
Businesses do not need more AI demos. They need systems that survive the real world.
Live today
- Public academy with free resources behind a lead form
- Instagram comment to DM funnel, proven in production
- Private operations panel: leads, triggers, content approval
- Plain Postgres with numbered SQL, Docker, Coolify and systemd timers

06Lab and offline
Experiments, side quests and useful mistakes.
The Lab is where small tools, AI workflows and physical ideas can be tested without pretending every experiment is a startup.

Enough about work.
Outside the screen: photography, coffee, 3D printing, travel, Brazil, Portugal and making random things just to understand how they work.
