Designing, implementing and scaling up the market leading B2B platform for swap and cross-chain transfer ops of any crypto assets. Integration and aggregations of most blockchains, tokens, DEXs and bridges. Compute best transfer routes, provide quotes and corresponding onchain transactions. Design, implementation, deployment and maintenance of enterprise-grade cloud services for the market leading cross-chain aggregator of DEXs, bridges and intents solutions: • orchestrate the aggregation of exchange routes for 3M+ asset tokens among 60+ DEXs and bridges, over 20+ blockchains: maintain and introduce new B2B APIs, async workers, 3rd parties API/SDK/chain integration. • build chain specific transactions, simulate tx execution, integrate smart contracts, introduce new fee models and manage revenue streams, enable the live indexing of onchain transfers and analytics reporting. • troubleshoot and fix numerous API overloads faced above 1.2M req/min through memory, computation paths, http, RPC and DB requests review, caching and optimizations. Overall improvement of errors handling and platforms’ runtime observability, for better scaling and a 2-3x faster SLA, diagnosis and customer tech support. Adapt our analysis, design and review processes, coding practices, scope and responsibilities by adopting latest AI computation and integration frameworks for 3-4x productivity gains via the development of tools, skills, agents and automated workflows — while increasing the quality and maintainability of products.

Strengthening dev teams building Web3-related businesses. My areas of expertise include functional design & software architecture, coding-reviewing-testing in DevOps contexts, integration of 3rd parties and deployment of distributed Web applications. Blockchain protocols and smart contracts on Ethereum & Cosmos chains (EVM/Solidity, CosmWasm/Rust), cloud-based secure and scalable backend services (Node.js, Go, gRPC, Java Spring, RESTful API, Kafka, Redis, Mongo, Kubernetes) are my key ingredients, as well as evolutive Web applications. Organizations benefit from my strong problem-solving skills, my team mindset and my industrial software engineering experience. I take part in several [DAO] dev communities since 2018. I have been certified by the Interchain Developer Academy and I participate in hackathons. I continuously learn in this fast-paced context and tackle challenges with the most adapted tech and best practices.
