// about

Senior fullstack software engineer with ~10 years building and scaling backend systems. I specialize in Node.js, TypeScript and event-driven architecture on AWS — designing serverless platforms, pricing engines and microservices for products used by millions. I care about domain-driven design, clean architecture and shipping reliable software. Based in Lima, Peru, working remotely.

   • Migrated infrastructure from Google Cloud to AWS, setting up VPCs, subnets and security groups.

4. Software Consultant / Technical Leader @ Globant

   Mar 2018 — Jan 2021

   Remote

• Localy.lat ↗ — Event-venue marketplace platform

  2025 — Present

  A platform connecting people with event venues, built end to end with Domain-Driven Design and running on a fully AWS-native infrastructure.

  • Migrated the platform from Supabase/Vercel to a fully AWS-native stack — Next.js deployed via OpenNext (CloudFront, Lambda, S3) and provisioned as infrastructure-as-code with SST.
  • Moved persistence to PostgreSQL on Amazon RDS and added event-driven processing with Lambda and SQS.
  • Automated deployments with an AWS CodePipeline CI/CD flow; DNS and content delivery via Route 53 and CloudFront.
  • Built user, host and admin modules — multi-step host onboarding, admin dashboards, Google auth and Google Maps integration.
