About me

Software Architect and Distributed Systems Engineer with over 10 years of experience designing, evolving, and operating cloud-native and edge-first applications, focused on low latency, horizontal scalability, and production resilience. Specialized in distributed systems, microservices, event-driven architectures, edge runtimes, and WebAssembly (WASM), with primary expertise in Go, Rust, and TypeScript. Responsible for architectural definition and technology selection, continuously balancing trade-offs between consistency, cost, throughput, and operational complexity.

My engineering approach is grounded in solid software engineering principles, with consistent application of Clean Architecture, SOLID, DDD, TDD, and CQRS. Security is treated as a fundamental requirement across the entire stack — secure by design, OWASP Top 10, hardening, and dependency analysis.

Professional Journey

2014 — 2026 · 12 years
Software Architect & Distributed Systems Engineer
Arkana Studios · Freelancer
Manaus, AM — remote work for clients across multiple industries
  • Designed and evolved distributed applications using TypeScript, Go, and Rust, building REST and GraphQL APIs and modern applications focused on performance, scalability, and operational reliability.
  • Implemented edge-native architectures using Cloudflare Workers, Pages, KV, D1, Queues, R2, and Durable Objects, reducing latency and operational costs for geographically distributed applications.
  • Structured CI/CD pipelines with staging environments, automated deployments, and rollback strategies, accelerating delivery cycles and reducing production incidents.
  • Optimized critical workloads through query restructuring and Redis-based caching strategies, reducing database load and improving response times in high-traffic applications.
  • Applied defensive security practices from the architectural phase, including threat modeling, input validation, dependency review, and strategies aligned with OWASP Top 10.
  • Provisioned and operated distributed infrastructure on Cloudflare, AWS, and OCI, including observability, WAF, DDoS protection, TLS certificates, hardening, and continuous monitoring.
  • Consistently applied Clean Architecture, SOLID, DDD, TDD, and CQRS, with security treated as a fundamental requirement across the entire stack (secure by design).
  • Served clients in retail, healthcare, education, finance, and real estate sectors.

What sets me apart

Distributed systems architecture — solid experience designing highly complex systems with deliberate trade-off analysis between consistency, cost, throughput, and operational complexity.

Cloud-native & edge-first — deep specialization in Cloudflare Workers, Durable Objects, D1, KV, R2, and Queues, building globally distributed applications with minimal latency.

Complete full stack vision — from front-end to infrastructure and production operations, with end-to-end ownership and no dependency on other teams.

Diverse core stack — mastery of Go, Rust and TypeScript as primary languages, with the ability to choose the right tool for each problem — including WebAssembly for edge workloads.

Security as a fundamental requirement — secure by design applied across the entire stack — not as an afterthought, but as part of the architecture from the start.

Continuous learning — over 170 courses completed in software engineering, systems architecture, cloud computing, and application security.
