Mariana B.

Sobre o Profissional

  • ? Backend Engineer building production-grade software that scales.

    I specialize in developing high-quality, robust, and fast software systems.
    Not just code that works—software architected for scale, reliability, and real-world production use.

    **What I do:**
    - Build backend systems in Go and Rust with focus on performance and scalability
    - Design distributed systems that handle real-world traffic and failure scenarios
    - Implement infrastructure-as-code and DevOps practices ensuring reliable deployments
    - Architect systems for reliability, observability, and cost-efficiency
    - Debug complex production issues across multiple layers (application, database, infrastructure)

    **Why work with me:**
    ✅ Production mindset — every line of code is written with scale and reliability in mind
    ✅ Full ownership — I don't just deliver code, I deliver solutions
    ✅ Fast delivery — efficient execution without compromising quality
    ✅ Communication — clear updates, no surprises
    ✅ End-to-end expertise — from architecture to deployment to monitoring

    **Tech stack:**
    Go, Rust, Python, Kubernetes, Docker, AWS, PostgreSQL, Redis, distributed systems,
    CI/CD, infrastructure-as-code, observability, system design.

    **Recent work:**
    - Built B2B SaaS marketplace in Go (hexagonal architecture, RabbitMQ, zero-downtime deployment)
    - Engineered AI-powered application (Rust backend + Python services via gRPC)
    - Architected and optimized distributed systems supporting 10K+ concurrent users at 99.9% availability
    - Led infrastructure modernization reducing costs by 60% while improving reliability

    Ready to discuss your project. Let's build something reliable and fast.

    ? CORE PRINCIPLES
    Quality First
    Every line of code is written with production in mind. Not just functional—robust, tested, and reliable.
    Scalability by Default
    Architecture decisions consider future scale. Systems designed to grow without major rewrites.
    Performance Matters
    Fast systems are more reliable systems. I optimize for speed without compromising correctness.
    Reliability is Non-Negotiable
    SLOs, observability, incident response—production systems need all of it. I deliver systems that stay up.
    Communication & Transparency
    Regular updates, clear estimates, honest about challenges. You know what's happening, always.
