Acerca de Miguel
Senior Python Backend Engineer with 6+ years of experience designing, building and maintaining backend systems, APIs, integrations and platform tooling in technically complex environments.
I have worked across fintech, trading, blockchain, data architecture, telco and AI-assisted software modernization, contributing to projects where reliability, scalability and clear technical design are essential.
My core experience includes:
• Python backend development with Flask and FastAPI
• REST API design, internal services and system integrations
• PostgreSQL, SQLAlchemy, data modeling and query optimization
• Trading systems, automation, market-making tooling and real-time market data
• WebSockets, Kafka, microservices and event-driven architectures
• Blockchain infrastructure, explorers, protocol indexing and smart contract tooling
• AI/LLM-assisted platforms for legacy code analysis, documentation and modernization
I enjoy working on complex technical problems, understanding the domain before building, and designing solutions that are reliable, maintainable and easy to evolve.
I am currently open to remote Senior Python Backend Engineer opportunities, especially in backend architecture, API design, platform engineering, trading systems, blockchain infrastructure, DeFi, AI platforms and developer tooling.
