Almost a decade delivering systems at scale, I build services that ship reliably and stay easy to maintain as complexity grows. I work across the full lifecycle from distributed service design and cloud-native infrastructure to automated delivery and production observability. Keeping platforms stable, performant, and resilient as they evolve is my core focus. I also contribute to open-source software that powers the modern web.

• Languages: Python, TypeScript, Java, C/C++, Rust
• Frameworks & Libraries: NestJS, FastAPI, Django, Express, TypeORM, Prisma
• Databases & Messaging: PostgreSQL, MongoDB, Redis, RabbitMQ
• Architecture: SOLID, Microservices, Event-Driven Architecture, CQRS, Event Sourcing
• Web & Security: REST, OpenAPI, OpenTelemetry, OAuth 2.0, OIDC, JWT, Zero-Trust
• DevOps & GitOps: Docker, Kubernetes, Grafana, GitHub Actions, Bitbucket Pipelines, ArgoCD

VOID - Tecnologia e Comunicação | Senior Backend and DevOps Engineer At VOID, I scaled an enterprise loyalty platform by building containerized Node.js microservices orchestrated with Kubernetes. I drove the implementation of an event-driven architecture to automate reward flows while designing fault-isolated deployments that maintained platform stability during high-traffic periods. Additionally, I contributed to agricultural analytics by processing satellite imagery with Python and QGIS, leveraging machine learning to track plant health and improve spatial decision-making through geospatial mappings.

DSAI4MOZ | Data Engineer As a Data Engineer, I built and maintained scalable batch and streaming data pipelines using Airflow and Kafka to ensure high data reliability. I optimized complex ETL workflows and warehouse queries, drastically reducing processing time and cloud costs. By introducing rigorous data quality checks and robust monitoring, logging, and alerting systems, I ensured consistent data consumption and significantly lowered issue detection times.

Node.js & Deno | Open-Source Developer I actively contributed to modern JavaScript runtimes, enhancing testing reliability and system compatibility. In Node.js, I improved the test runner by standardizing signal exit codes and fixed strict equality assertions in the compatibility layer. For Deno, I resolved critical directory conflicts affecting tools like SvelteKit and exposed robust SQLite backup functionality by integrating Rust operations, improving overall API parity and platform stability.

MINDERA | Specialist Software Engineer At Mindera, I engineered scalable, high-concurrency backend services and event-driven APIs for major clients, including IAG Loyalty, Marks & Spencer, Waitrose, Dunelm, and FanDuel. My work focused on optimizing system performance through streaming exports and server-side caching, integrating reliable third-party systems, and improving checkout flows. Working across distributed teams, I established strong backend coding standards, automated delivery pipelines via AWS, and actively mentored junior engineers.
