The Problem

The market shifted. The question is: are you ready?

AI tools emerge overnight, stacks go stale in months, and the gap between building right and building wrong can cost you a full quarter — or the entire product.

The Non-Technical Founder

You have a clear idea, market validation, and maybe even investors interested — but you don't know how to structure what comes next.

  • Difficulty choosing the right tech stack
  • Fear of hiring devs without technical criteria
  • MVP that could turn into massive technical debt

The Fast-Growing Startup

The product is live, but the codebase has become a maze. You want to scale and integrate AI, but lack technical direction.

  • Dev team without strategic leadership
  • Technical decisions made without product alignment
  • Scaling without breaking what already works

The Established Company Needing AI

You already have a product and a team. But AI isn't just a feature — it's an architecture decision most teams don't know where to start with.

  • Implementing AI without compromising current architecture
  • Evaluating tools: RAG, agents, fine-tuning
  • Creating real value — not just AI for show
The Solution

Alessandro Sales doesn't just deliver code.
He delivers clarity.

With 15 years of experience as a senior fullstack engineer, technical team leader, and applied AI practitioner, I work as a strategic partner across three fronts.

Architecture & Technical Planning

Before a single line of code is written, I help you define the right stack, a scalable architecture, the risks — and how to structure your team.

  • Stack and architecture suited to your context
  • Technical risk mapping
  • Technical roadmap aligned to product strategy

Applied AI Engineering

I map where AI creates real value in your product — through agents, RAG, LLM integrations — as part of the architecture, not as a bolted-on plugin.

  • Agents with memory and tools
  • RAG pipelines with proprietary knowledge base
  • Automations via WhatsApp and MCP

Technical Leadership & Execution

Your fractional CTO, the technical lead for your team, the architect of your MVP, or the senior engineer who makes sure what was planned actually ships.

  • Dev team management and mentorship
  • Stakeholder communication
  • From strategic to operational
Why Me

Why Alessandro and not just another senior dev?

15 years of consistent delivery isn't just technical experience — it's clarity about what actually moves the needle.

View available services

I speak both business and engineering

I translate business requirements into architecture decisions — and vice versa. 15 years of experience from code to stakeholder.

AI-powered SaaS products in production

I built Slag, Aicon, and EUTEC: real agents, real RAG, real WhatsApp integration. I don't study AI in courses.

Product thinking, not feature thinking

I don't deliver what you asked for. I deliver what you actually need — even if it's different from what you imagined.

Real commitment, no bureaucracy

Direct communication, planned deliveries, and autonomy for technical decisions. Speed without sacrificing quality.

How We Work Together

From first contact to a running product

A direct process, no fluff, with full visibility at every step.

01

Diagnosis

A focused conversation about your context: where you are, where you want to go, and what the biggest technical blockers are right now. No commitment.

02

Strategic Proposal

Based on the diagnosis, I present what to do, in what order, with what stack and what risks — and how I can play a role.

03

Execution with Visibility

Every phase delivered with documentation, active communication, and room for adjustments. You're never in the dark about what's being built.

04

Autonomy Transfer

At the end of each cycle, you walk away with code, documentation, and — when it makes sense — training so your team can operate independently.

Services

What I can do for your project

Each service can be contracted independently or combined depending on your product's current stage.

Consulting

Architecture & Technical Planning

For teams who need to get the foundation right before building. Ideal for non-technical founders, CTOs seeking a second opinion, and companies navigating a tech pivot.

  • Tech stack review and selection
  • Architecture planning (monolith, microservices, serverless)
  • Technical risk and tech debt mapping
  • Technical roadmap aligned to product strategy
AI Engineering

Applied AI Engineering

For companies that want to integrate AI the right way — not as hype, but as a concrete competitive advantage embedded in the architecture.

  • LLM API integrations (OpenAI, Anthropic, and others)
  • Agent systems with memory and tools (Agno, LangGraph)
  • RAG pipelines with proprietary knowledge bases
  • Intelligent automations with n8n + Evolution API (WhatsApp)
Development

SaaS Product Development

For teams that need end-to-end technical execution — from MVP to scalable product with a well-planned architecture.

  • Robust backend with Node.js/NestJS or Python/FastAPI
  • Modern frontend with Vue 3/Quasar or React
  • Infrastructure with Docker, PostgreSQL, Redis
  • Payment integrations (Asaas, Stripe)
Leadership

Technical Leadership (Fractional CTO)

For startups that need senior technical leadership without hiring a full-time CTO. Strategic presence when and how you need it.

  • Dev team management and mentorship
  • Technical decision-making and prioritization
  • Investor and stakeholder communication
  • Code review and engineering standards

FAQ

Common questions

If your question isn't here, the best way is a direct conversation — no forms, no waiting.

Ask a direct question →

I work on project-based contracts, monthly retainers (for ongoing consulting or technical leadership), and hourly engagements for one-off advisory sessions. The right model depends on what you need — we'll figure it out together in the first conversation.

Absolutely. Architecture consulting and technical planning is a standalone service. Many clients hire me to validate decisions, review roadmaps, or define stacks before assembling an internal team.

Both. I can step in as technical leadership for existing teams, audit legacy codebases, propose incremental improvements, and serve as the bridge between engineering and the business.

I have AI products in production: agents with memory, RAG pipelines, LLM-driven automations, and WhatsApp integrations. I don't sell AI promises — I deliver AI architecture.

Early-stage startups that need technical structure, mid-sized companies looking to integrate AI without building a large team, and founders who need a trusted technical partner to bring their vision to life.

Yes. I work fully remote with clients across Brazil and internationally. I'm comfortable working in English and communicating with global teams.

Next Step

You don't need another developer.
You need someone who builds alongside you.

Whether you're planning a product, have a project stuck in limbo, or want to know how to integrate AI strategically — this conversation could change the direction of what you're building.

No commitment. Straight to the point.
