Mid-level Full Stack Developer with 6+ years building web and mobile applications, REST/GraphQL APIs, and cloud backends on AWS and Azure. I work across the stack, with a focus on backend: APIs, third-party integrations, and asynchronous, event-driven workflows.
At Kovix (2024–2026) I joined the team behind Recyco, a backoffice and React Native app for municipal recycling collection in Argentina, covering route planning, operational tracking, and field logistics (React, Node.js, GraphQL, PostgreSQL, AWS). I developed features across web, mobile, and backend, including work on the HERE Tour Planning routing integration. With HERE, Recyco reduced average route time by 20% and fuel costs by 17%, while handling 3x more waypoints per route. I also developed backend services for Tough Day, an AI-powered assistant for management teams, integrating business data, third-party services, and LLM capabilities with background jobs and queues (NestJS, Next.js).
At ActiveOne Solutions (2019–2024) I worked with international clients in English-speaking teams:
• EFactura: e-invoicing API integrated with Colombia’s tax authority (DIAN), processing millions of invoices (Python, Spring Boot, AWS, MongoDB).
• RIPS: serverless validator for large healthcare files on AWS Lambda.
• Trident Trust: legal and tax portals for a global fiduciary firm with 30+ offices, serving companies in the BVI, Panama, and Nevis.
• Esfasil: mortgage-simulation services for a fintech startup.
I also redesigned a legacy reporting module, optimizing queries, adding caching, and removing duplicated code.
I’m looking for remote full stack or backend roles with teams in American time zones.
