Senior Backend Engineer — DeFi & Trading Infrastructure
About Me
I am a senior backend engineer with more than 10 years of experience, and for the last 7 years I have focused on crypto trading infrastructure, DeFi systems, and blockchain integrations. My work has centered on building reliable backend platforms for exchange connectivity, market-making, and risk analysis.
I have extensive hands-on experience with Go, TypeScript, Python, Rust, and Solidity, and I regularly work with EVM-based tooling, smart contracts, and Web3 infrastructure. I have also built systems using gRPC, GraphQL, REST, PostgreSQL, Redis, Kubernetes, Docker, AWS, and GCP.
At Enflux, I helped scale a market-making platform to more than 500 bots across 30+ servers and developed DEX/CEX connectors and real-time trading microservices. I also contributed to a TradeOps dashboard for managing trading bots and supported open-source work.
At Emporus, I am building automated risk systems for DeFi projects, including strategy simulation, external service integrations, blockchain data classification, and liquidity pool state tracking. This role has strengthened my experience in DeFi architecture and production-grade Web3 systems.
Earlier in my career, I worked on blockchain explorers, crypto exchange applications, wallet integrations, and backend tools for high-throughput systems. I have also led teams and managed projects, combining technical execution with coordination and delivery.
I am based in Lisbon, Portugal, and I am open to remote work within the EU. I bring a strong background in backend engineering, blockchain infrastructure, and product-focused development for crypto and fintech environments.
