• What Hackathons Teach You That Jobs Can’t - building under compression, deciding faster, and learning from elite builders.
• USDC Fixed-Fee Hook - a Uniswap v4 hook for fixed USDC swap fees, gas hedging, and account abstraction.
• The Engineer Without a CS Degree - how business school, Linux, and product work shaped my engineering path.
• Building for LatAm - product constraints in markets where the Silicon Valley SaaS playbook breaks.
• The “SaaSpocalypse” Isn’t Real - why LLMs reshape interfaces without replacing durable state machines.
• ML and MLOps: learning notes 1 - corrected notes on PyTorch, activations, gradient descent, MLOps, GPUs, stochastic inference, and agents.
• Primero hazlo “naive”, después hazlo mejor - start manual, learn the system, then automate what survives contact with reality.

Current Threads

• AI systems: agentic workflows, deterministic interfaces over stochastic models, and multi-tenant infrastructure for agents.
• DeFi and market structure: on-chain price discovery, Uniswap v4 hooks, gas abstraction, tokenized contracts, and financial primitives that need better markets.
• LatAm products: distribution, low-bandwidth systems, payments, and pragmatic software for messy operating environments.
• Personal engineering craft: fast iteration, infrastructure taste, and the habit of turning projects into reusable knowledge.
