• Tonkeeper focuses on developing a mobile crypto wallet and providing tools and services for the TON blockchain. I worked on multiple projects including building an index of the blockchain and exposing it through an API.
• My contributions:
• Developed a relayer service for gasless transactions in TONAPI — now used by @wallet, Tonkeeper, and Tether.
• Created a webhook notification system for real-time event tracking on the TON blockchain.
• Designed and contributed to GraphQL, Streaming, and REST APIs in TONAPI to provide public access to blockchain index data.
• Improved and extended an internal Golang blockchain interaction library by implementing missing features required for indexing. Significantly boosted performance, added testing coverage, and built a CI pipeline.
• Implemented support for multiple TON standards in the TONAPI indexer.

• Shipa is a cloud-native platform for developers and platform engineers that simplifies deployment and management of containerized applications on Kubernetes.
• Technologies: Go, kubernetes, kubernetes client-go, controller-runtime, kubebuilder, helm, buildkit, containerd, docker, prometheus, traefik, istio, mongodb, etcd, clair, swagger, aws
• My contributions:
• Designed and implemented the initial version of Ketch, which is an application delivery framework for Kubernetes. Ketch simplifies support and maintenance by operating from the perspective of an application context instead of object context.
• Worked on a CI/CD pipeline and an internal testing framework to improve platform quality.
• Worked on exporting metrics of users’ applications and the platform to Prometheus to provide visibility to users and improve Shipa’s platform.
• Designed and worked with the team to implement multiple features of Shipa like canary deployments for multiple ingress controllers, discovering applications on Kubernetes based on given labels, real time policy violation reports for discovered applications, integrations with Traefik, Istio, Clair, and docker registry.
• Mentoring other developers and helping to improve the capabilities of the engineering team.

• I was responsible for leading a team of five software engineers, and ensuring the use of good engineering practices like code review, CI/CD, code testing, implementing server-side parts, as well as gathering client’s requirements and negotiating deadlines..
• I worked on two projects:
• 1) Waitre.com - Waitre is a cloud-based system to manage inventory, staff, and sales with an iPad POS system designed for food and beverage businesses. The team under my lead designed and implemented the system as a microservice solution hosted in kubernetes cluster on Google Cloud. We use unit tests and integration tests deeply built into our delivery pipeline to increase the quality of our solution.

• Designed and implemented REST API for web and mobile clients
• Implemented advanced warehouse solution
• Built continuous integration and delivery pipeline that decreased time of build, test, deploy cycle
• Built monitoring, exported application’s metrics to prometheus and optimized performance
• 2) Delivery calculator - Software that helps spare parts shop to provide an optimal delivery service to their customers. Managers can quickly pick up the most appropriate option of several delivery services that are available for a desired location.
• Technologies: python, tornado, sqlalchemy, mysql, redis, rabbitmq, soap
• Key mission-critical achievements:
• Designed and implemented a simple and unified REST API for frontend developer
• Connected to 9 delivery services that use different APIs
• Implemented synchronization logic that helps keep the internal database state up to date with external services

• During my contracting I worked on a wide range of different projects using the most suitable tools. That allowed me to work on the majority of modern software stacks and understand their pros and cons. Some of the most interesting projects are:
• 1) Printing-Kiosk software - Public vending machine allowing customers to print documents.
• Implemented windows service to control system printing queue and gather information about printed documents (C#)
• Implemented windows service to control payment device NV9 and Smart Hopper from Innovative Technology (C#)
• 2) Instaprinter - Software used to understand the impact of public events on social networks. Visitors of the event share a photo with the event’s hashtag on social network, the software prints this photo on a color printer with customized effects, gathers statistics and generates event impact report.
• Developed MVP(C#, WPF) to validate the idea
• Built a full-featured desktop application
• 3) Assistant software for video editors - Software used to organize editors’ workflow: checkout customer’s video from a NAS based repository, prevent working simultaneously on the same material, synchronize local copy with company’s repository, understand who works on what, etc.
• Designed and implemented the desktop application (C#, WPF, sqlite)
• 4) Software for clothing manufacturer - Software to manage the manufacturer’s catalog of products in terms of operations and costs, calculate paychecks and taxes, and understand throughput and workload of manufacturing pipeline.
• Designed and implemented several desktop applications (C#, WPF, NHibernate, Microsoft SQL Server) for different roles (plant manager, accountant and operator) at manufacturing pipeline
• Implemented several types of report that were previously unavailable
• Etc. I wrote a lot and that helps me to get understanding of different technologies and stacks.
