Leading a team of 5 developers and 3 QAs as Team Lead and Scrum Master, designing the microservice architecture behind messaging platforms that processed 250M+ messages in 6 months.

• Lead a team of 5 developers and 3 QAs as Team Lead and Scrum Master, ensuring continuous delivery under tight deadlines.
• Designed the microservice architecture (Node.js, NestJS, Redis, BullMQ) for messaging platforms (SMS, WhatsApp Business API, SendGrid) that processed 250M+ messages in 6 months.
• Designed and implemented CI/CD pipelines (GitHub Actions, Bitbucket Pipelines), dockerizing and automating deployment for 8+ applications (15 min → 4-5 min) with blue-green releases on critical services; leading the migration of the rest, still on PM2.
• Implemented security controls following the OWASP Top 10: JWT + OTP, 2FA, password history/expiration, XSS/CSRF/SQL-injection mitigation, and rate limiting.
• Led an AI-assisted Angular modernization (v12 → v22), complete in 3 days versus 2 incomplete weeks on a prior manual attempt — reducing the bundle from ~50MB to 8MB and the build to 15 seconds; adopted Signals, Zoneless, and standalone components.
• Designed and scaled, with AI assistance, a vulnerability audit and mitigation process across 10+ projects in parallel, reducing response time from days to minutes; now company standard.
• Directed the migration of users from a legacy messaging system to the new one, with scripts and processes that preserved credentials and guaranteed data integrity with zero friction for clients.
• Designed and led the migration of reporting to AWS Athena + S3 (3-6 min with failures → 30-60 sec) and the centralization of files in S3, reducing risk under high demand.
• Built an internal MCP server for AI agents and the official integration documentation (Astro + Starlight) delivered to clients; defines architecture standards and mentors senior and junior developers.

Frontend and backend features across microservice architectures for large-scale communication products, including a high-availability SMS banking service.

• Developed frontend and backend features (Angular, Node.js, NestJS, MySQL, Redis) across microservice architectures for large-scale communication products.
• Designed and built messaging integrations with the WhatsApp Business API (Meta) and SendGrid (email/WhatsApp), including delivery-status webhooks for every message.
• As part of the team, designed and built a high-availability SMS banking service (SINPE, Costa Rica): high request volume, Redis + BullMQ queues, delivery-status webhooks, retries, and monitoring.
• Built queueing systems with Redis and BullMQ (pub/sub, locks, Lua scripts, cluster mode), with automatic retries and idempotency across queries, users, and API keys.
• Contributed to production monitoring (Prometheus, Sentry, structured logging) and vulnerability mitigation for the project, improving stability under high traffic.
