Back to original languageAbout Tristan
I am a senior backend developer specializing in Rust, Go, application security, and artificial intelligence system integration.
In recent years, I have focused particularly on three areas:
- Backend and distributed systems development, with a strong emphasis on Rust and Go, around APIs, microservices, gRPC communications, message queues, asynchronous processing, and PostgreSQL databases.
- AI applied to product development, including the design of AI agents, tool-use logic, multi-agent pipelines, lightweight RAG components, and integrations with various model providers like OpenAI, Anthropic, DeepSeek, or xAI.
- Security, both on the architectural and product sides, involving audits, hardening, risk analysis, API security, and attack surface reduction on exposed systems.
Notably, I have worked on:
- Hugging Face, on backend, infrastructure, security, and orchestration topics related to machine learning.
- Beside, on backend, agentic, and security features within a Go, gRPC, PostgreSQL, and AWS stack.
- Applied research projects for securing prompts and LLM calls.
- Rust and Go architectures in sensitive contexts, including industrial, banking, defense, and SaaS.
Specifically, I can contribute to:
- Designing and implementing robust APIs.
- Developing microservices and distributed systems.
- Data modeling and PostgreSQL optimization.
- Setting up clean and maintainable Rust or Go architectures.
- Integrating AI into existing products.
- Creating AI agents and multi-agent workflows.
- Securing an architecture or codebase.
- Technical audits, architecture reviews, and taking over complex projects.
