• Led the design and implementation of the initial MVP of Platflow.ai in conjunction with team members to demonstrate the feasibility of the product and gain investment to launch the company.
• Developed the foundational architecture for user management and accounting (e.g., how to track users throughout their lifecycle, how to manage users’ access rights, how to track activity and usage for a multi-tenant / multi-user AI platform).
• Created, built, and maintained administrative operations (management) tooling internally via Retool to allow for rapid prototyping of administrative processes and lowered time to bring operational features to market.
• Led the development of the core browser extension (Chrome and Edge) that functioned as the main surface for the product. This extension had a great amount of client-side and middle-tier logic in addition to transforming raw, unstructured data into formalized, reusable UI components and AI-ready data to be sent to the server.
• Designed an architecture that was modular, well-isolated, and would allow the system to be maintainable and adaptable despite changes to product requirements, user experience (UX), and overall company goals.
• Managed complex data flows, state management and lifecycle of the extension while optimizing for performance, reliability, and ease of development within a complex browser environment.

• As a Full Stack Engineer, I was accountable for the design and structure of middle-end/front-end systems/tasks.
• I created and structured the Layer 2 - Middle Tier to serve as a coordinator between UI/Presentation Layer and the backend (Authentication Flows, Request Orchestration, Data Normalization).
• I designed and developed a front-end form system with dynamic, rule-based forms using React, FlowType and styled-components. The forms used complex branching logic and conditional flows, allowing configuration changes to Siloed Products and/or Platforms to be done in subsequent weeks instead of a few months.
• I wrote comprehensive unit tests using Jest to ensure the reliability and maintainability of core product related logic and user interface based components.
• I optimized the performance of React components and rendering paths to improve speed/responsiveness, reduce unnecessary re-renders and maintain speed/responsiveness under highly complex form states (especially in regards to component hierarchy, React's Virtual DOM, etc).
• I worked directly with back-end engineer to create clean API contracts, predictable data flows and appropriate error handling across the bootstrapped application.
• I actively participated in daily stand ups, sprint planning/estimation sessions and raised risk items, blockers and architectural concerns/proposals as needed to maintain deliverables in line with business goals and timelines.
• The platform proved strong commercial and technical value and was successfully acquired twice during its lifecycle, with the final acquisition completed by Kingsbridge Insurance.

• Got a promotion from being a Junior Engineer to taking on the role of Team Lead / Technical Lead during my time at this engagement. With both a technical and leadership responsibility.
• I led and provided direction for the front end and back end team that consisted of up to 12 engineers across a variety of functional disciplines. I was responsible for task allocation, due date delivery, and technical quality of the teams.
• I was actively involved in hiring, onboarding, development of engineers through mentoring and providing guidance on performance, and promoting strong engineering practices and teamwork.
• I wrote technical specifications and architectural proposals and worked closely with clients and project managers to convert business requirements into scalable technical systems.
• I designed and developed a number of single-page applications (SPAs) utilizing Angular, Knockout, Socket.io, and Node.js. Emphasizing real-time interaction and delivering a rich client-side experience.
• One of the major projects I worked on was the design and development of an enterprise-level task and workflow management system similar to Asana and Jira that will allow for assigning tasks, tracking progress, providing notifications, and visibility to clients.
• Took part in a major-scale enterprise project with close to 500 individual people from different organisations working together as part of a distributed team to design and build custom developed software using TypeScript for the Digital Operations Systems (DOS). The complexity and magnitude of this project is equal to McDonald’s own internal systems.
• Provided technical leadership for clients through the design of solutions and the selection of appropriate architecture and technology.

Jun 2010 – Feb 2012 · 1 yr 8 mos · Kharkov

• Developed internal enterprise web applications as a Software Engineer with a concentration on creating data driven systems.
• Developed and implemented an internal Meeting Room Booking system for all employees to use as their calendar to schedule rooms for independently reserving rooms and resolving conflicts over reservations, using that as the main Corporate Calendar.
• Designed and implemented an authentication and access control mechanism to authenticate users to the Meeting Room Booking system in accordance with LDAP meeting many Corporate identity and security standards.
• Developed a single-page application(SPA) for the Meeting Room Booking System project, at the time of initial development there was still a large amount of uncertainty regarding the future viability of this type of architecture and the application was based on the Yahoo User Interface (YUI), allowing for a high degree of interactivity with the end-users.
• Designed and developed extensive relational databases (MySQL) that included schema designs, query optimizations, and ensuring highlevels of data integrity and performance for severalhigh frequency useages within a limited period oftime.
• Created and maintained complex PHP logic for supporting scheduling work-flows, decision support systems, and scalable business rules for the Meeting Room Booking system.
• Collaborated with company stakeholders (Users) to evolve and improve functionality within existing production systems while maintaining system stability and backward compatibility of all existing production systems.
