Qualificações

• 7+ years of professional experience building, scaling, and supporting backend systems in production.

• Strong database architecture skills and a track record of optimizing backend performance on a high-traffic, user-facing product.
• Experience with cloud infrastructure and services, preferably AWS.

• Translate product requirements into maintainable, well-structured backend systems.
• Build systems that perform reliably under real-time load in a fast-moving production environment.
• Write and review technical designs for backend systems.
• Identify architecture tradeoffs and recommend pragmatic solutions that balance speed, quality, scalability, and maintainability.
• Lead complex initiatives involving data modeling, database performance, asynchronous processing, and platform services, including the rollout of ScyllaDB alongside MongoDB.
• Optimize queries, data access, and service performance for a high-traffic, real-time platform.
• Diagnose production issues using Sentry, CloudWatch, logs, metrics, and alerts, and follow through with fixes that last.
• Reduce regressions and make backend systems easier to understand, operate, debug, and extend over time.
