Experience
Low-code Development Platform
A web-based platform written in Kotlin and Java for designing data routes, APIs, and services in a visual builder following enterprise integration patterns (EIP), then deploying the artifacts to a multitenant Kubernetes environment and streaming runtime data back to the client's browser.
Ridesharing Service | Fasten
I developed a commercial ridesharing service which connected drivers and passengers. The serviced was aimed for the US market so it was necessary to integrate it with local payment providers. Its main competitors are Uber, Lyft, etc. The application is modular and scalable with a service-oriented design. I designed and implemented the billing functionality, the gateways for integration with payment providers, and some essential business logic.
US Electional Analytics Portal
I developed an intranet analytics portal for an authoritative US-based media company. The application aggregates open data about presidential and gubernatorial elections media campaigns, and provides a dashboard for the reporting using D3.js geographical maps and flexible charts.
Integration | Magnit
I designed and developed inter-application data exchange in the largest Russian retailer with a wide geography. My team implemented highload data flows which handled millions messages daily, monitoring and audit system, and guaranteed delivery mechanisms. I dealt with the application architecture, development, team management, and department work planning at different times.
Integrating Financial Software
I designed and implemented complex data flows that integrated an investment management solution with outer applications using Talend Open Studio. Introduced supplementary features on top of the Talend ESB basic functionality: extended logging, tracing, and inter-job communication. I used Zoho CRM API for some of the data flows. I also consulted with the customer on the possible pitfalls of integration and designed the solutions.
Family Device Management
I developed a portal for managing devices (desktops, laptops, tablets and smartphones) of family members. It provided functions to create rules and restrictions for these gadgets, e.g, parental control or scheduled updates. The portal has an application store supporting various platforms. I implemented an API for connecting the portal with different platforms. The portal works with iOS mobile device management. I created the application store from scratch and supplied it with administrative tools.
docIO ECM
I designed and developed a task management system with an embedded document storage. Its main purpose was to store documents along with their version history and to attach them to manageable typed tasks.
