I'm a Software Engineer based in Colombia 🇨🇴 with 12+ years of experience building high-scale distributed systems, security/identity infrastructure, and developer tooling. My primary focus is Go, system performance, and crafting delightful developer experiences.

• Developer Tooling & Infrastructure: Built and maintained tools to streamline developer workflows: Schema registries, API contracts, CLI tools. (ex-Twilio, ex-Buf).
• Distributed Systems & Performance: Architecting low-latency high-availability backends with REST/Protobuf, storage, caches, dabatases.
• Technical Leadership: Balancing hands-on engineering with system design, RFC proposals, and cross-functional architectural alignment.

• Buf (Schema Registry): Engineered a Content-Addressable Storage (CAS) migration with cryptographic tamper-proofing for Protobuf modules, and redesigned the commit/label versioning system with zero downtime.
• Twilio (Branded Calls & Verify API): Architected the high-availability backend for Branded Calls (<100ms latency at global scale) and led technical evolutions for global Verify OTP verification across SMS, Voice, Push, and WhatsApp.
• Open Source Contributions: Contributed to Toggl’s open-source client (automated Pomodoro break feature) and built custom developer CLI tools.

• Samplr — A language-agnostic CLI tool to automate the generation of updated, committable sample files while keeping local secrets .gitignored using regex keywords.
• Community Managed Modules Syncer — Synchronization engine leveraging Content-Addressable Storage (CAS) for open-source Protobuf ecosystems.

• Languages & Core: Go • REST • Protobuf • SQL • Ruby • Rails
• Infrastructure & Storage: Docker • Redis • PostgreSQL • MongoDB • AWS
• Patterns & Architecture: Distributed Systems • Content-Addressable Storage (CAS) • Microservices • RESTful APIs

• 🎾 Tennis: Playing clay court tennis 3-4 times a week.
• 🎬 Cinema & Books: Avid reader and listener of personal finance & investment strategies, and regular cinema goer.
• 🐈 Home Life: Remote worker enjoying life in Bogotá with my partner and 3 cats.
