Personal summary

Please refer to my Linkedin profile

Over 20 years of working in the software development industry, I have matured my engineering profile as a researcher, tech expert, team leader and software architect at all back and front levels.

I have many experiences in production-grade backend services engineering for large product suites and customer delivery projects: from data models, protocols (p2p, consensus, RPC, so many), on-chain contracts (EVM, Solidity, Ethers.js, Hardhat, Tenderly; CosmWasm, Rust, IBC), Web SDKs (TS/JS, npm, redux, Ajax, gRPC), RESTful APIs (Express, Nest; Spring Boot, MVC, Hibernate, Swagger/OpenAPI; DDD; GraphQL; OAuth, JWT, PKI, ACL, RBAC), multi-tenant scaling microservices (Docker, Kubernetes, EDA with Kafka, Istio service mesh, Nginx), cloud hosting platforms & their services (AWS, Azure; Terraform; API gateway, load balancers), serverless architectures (Functions, EventsGrid) and cloud-based storage (MongoDB, Redis, PostgreSQL, S3 & EBS, IPFS). I am used to work in DevSecOps contexts (Jenkins, Github actions, GitLab flows, Sonar, Snyk), a.k.a. short, iterative, automated and continuous code-test-secure-deploy-release processes.

I am also proficient in Web client implementation (React.js, Sass, Node.js, Typescript), hybrid mobile apps (Android & Apple, Flutter, webview, push notifications, hooks), in integrating user analytic, building SDK libraries, as well as developing low-/no-code content authoring frameworks.

I am a pragmatic problem solver having great analytical skills to quickly adapt to business requirements and tackle technical challenges. I am engaged and authentic, always keen to learn, willing to contribute to the Web3 space in a highly professional manner.
