I co-invented/developed a censorship-resistant connectivity SDK that allows for internet access in various scenarios, including situations where internet freedom is limited. This technology significantly transforms how we look at internet architecture, enabling faster and more reliable internet connectivity in diverse end-user conditions. As a result, I am named as a co-inventor on a pending patent for this technology. In addition, I covered a wide range of scopes, including desktop, backend, and a tiny bit of hardware development, frontend, and DevOps. My tech stack in this role included Rust, Golang, WebRTC, Typescript/Javascript, Tauri, Cloudflare, Vercel, Docker, Kubernetes, Linux, TRPC, Fly.io, AWS, Nuxt, Vue.js, Node.js, GitHub Actions/Jenkins, PostgreSQL, Redis, and libp2p.

Backend, security, infrastructure, and innovation engineer.

Cloud solutions architect, full-stack development, web3, and security.

I created a real-time scalable media streaming broker with a custom in-house media codec for efficient compression and distribution in unreliable networks. The product featured facial recognition, personalization, and analytics for retail. I sold the intellectual property instead of starting a business due to lack of interest. Managing it alone was tough, especially with the war in my home country and unfavorable business conditions. Stack in this role: TypeScript, Node.js, Next.js, Vercel, GitHub Actions, Milvus, Neo4j, NATS, Elasticsearch, PostgreSQL, Python, TensorFlow, Kubernetes, Docker, Linux, React, Balena.io, C/C++, Golang, AWS, GCP, S3, RTSP, WebRTC.

As a full-stack engineer, I have had the opportunity to work on over 30 projects of varying sizes and complexities.  My work has ranged from small websites for local businesses to alpha prototypes for early-stage startups in the US, web3 projects, as well as consulting for large Ukrainian companies on security, cloud, and software architecture.  Through these experiences, I have honed my skills in developing scalable and robust solutions that meet each client's unique needs. I take pride in my ability to deliver projects on time and within budget, while also maintaining a high level of quality and attention to detail.  My experience as a freelance engineer has allowed me to work with a diverse range of clients, each with their own set of requirements and goals. This has given me a unique perspective on problem-solving and a deep understanding of the importance of effective communication and collaboration in achieving success. Stack during these projects has been diverse: PHP, Node.js, NW.js, Cordova, Capacitor, Angular, React, Vue,  Electron, PostgreSQL, MariaDB, MySQL, MongoDB, Redis, Memcached, Docker, Kubernetes, Linux, and various AWS and Azure services such as CosmosDB, DynamoDB, ECS, and SQS and more.
