Let's build something
worth shipping.
I'm a software developer with a mathematical background, passionate about AI, open source, and knowledge sharing. Let's build something together.
01 · Product dev
Web & product builds
From "we have an idea" to a product customers can log into. I design the architecture, build the first few iterations, and hand you a codebase your team can own.
- Next.js · TypeScript · Postgres
- Design systems & UI from scratch
- Deployed to AWS or Vercel
02 · AI integration
AI features & systems
Practical, production-grade integrations: retrieval, agents, vision, speech. I'll help you pick the right model and measure what's actually working.
- RAG pipelines, embeddings, evals
- Self-hosted & API-based models
- Python · PyTorch · Ollama · OpenAI
03 · Blockchain
Blockchain & smart contracts
NFT marketplaces, token systems, on-chain logic. I focus on boring, auditable, maintainable code — the kind that doesn't make the news.
- Solidity · Hardhat · Foundry
- Ethereum · Polygon · Solana
- Wallet + dApp integrations
How we'll work
Same four steps whether it's a weekend spike or a six-month engagement.
01
Conversation
A 30-minute call to understand what you're trying to build and what success looks like.
02
Proposal
A short written scope with milestones, assumptions, and honest trade-offs. No fluff.
03
Build
Weekly demos, shared repo from day one, and a communication style that matches your team's.
04
Handoff
Documentation, runbooks, and a transition plan so your team can confidently own what we built.
Selected work
“Alejandro is the rare engineer who can zoom from smart-contract internals to product strategy in a single meeting, and actually make useful contributions at both ends.”
Carla Mendez
CTO · Galos
“He shipped the first working version of our RAG pipeline in two weeks, and then — crucially — spent the next two teaching our team how to maintain it.”
Rodrigo Salas
Head of Eng · Laboratoria
