Hi, I'm
Jobelo Quintero
Principal Engineer

I build intelligent, decentralized systems — from smart contracts to autonomous AI agents.
About
I'm a principal engineer who builds at the intersection of blockchain, AI, and full-stack systems. Over the past decade, I've shipped everything from DeFi risk engines processing multi-chain data to SaaS platforms serving thousands of users — and more recently, AI agent systems that make engineering teams faster. I approach engineering as systems design: architecting the full stack from protocol-level smart contracts through frontend interfaces to AI agent orchestration layers. I don't just use AI tools — I build the agentic systems and use them to ship at 3x velocity without accumulating technical debt.

Experience
Principal Software Engineer
Webacy · San Francisco, US
Architecting a Web3 risk intelligence platform — from responsive dApp frontends to multi-chain backend APIs — analyzing wallets across 8+ EVM chains. Built ML-powered risk classifiers, data pipelines processing millions of transactions, and AI-augmented dev workflows that cut feature delivery time in half.
Freelance Software Engineer
Toptal · San Francisco, US
Shipped full-stack applications for clients across fintech, blockchain, and healthcare — from system architecture through deployment. Consulted on smart contract security reviews and designed AI agent workflows that accelerated client engineering teams.
Consulting Software Engineer
Integra Biosciences · San Francisco, US
Architected modular software for laboratory equipment — visual drag-and-drop experiment design, backend data pipelines for scientific workflows, and instrument communication layers serving research teams.
Staff Software Engineer
Miroculus · San Francisco, US
Built the software and frontend for a biotech device executing next-gen sequencing protocols — enabling non-engineers to design experiments across 5 workflows and 20+ operation sets. Work that contributed to the company's Series B.
Senior Frontend Developer — Tech Lead
Youse · Bogotá, CO
Led a cross-functional team of 5 developers, shipping 3 production insurance products (car, home, life) on time and within budget.
Featured Projects
MCP Agent Ecosystem
Built 3 production MCP servers connecting AI agents to Notion, GitHub, and domain-specific tools. Not a proof of concept — a daily-use system that powers AI-augmented development across the engineering team, replacing manual context-switching with agent-driven workflows.
Ticketing Platform
End-to-end SaaS product: Django API, Next.js frontend, React Native mobile app, and Terraform-managed multi-environment infrastructure on AWS with Stripe payments — from architecture to production deployment.
Laboratory Automation Platform
Architected modular software for laboratory equipment at Miroculus and Integra Biosciences — visual drag-and-drop experiment design, protocol translation algorithms supporting 20+ operation sets, and data pipelines for scientific instrument communication across 5 supported workflows.
