Professional Experience
Intobi | Full Stack Engineer | 05/2022 – 11/2025 | Kyiv, Ukraine
• Engineered full cycle web platforms using React, Next.js, Node.js, Python and .NET Core,
delivering applications that consistently maintained less than 200ms response times even during peak usage.
• Made a suite of RESTful APIs supporting user authentication, session tracking and real time data operations, which reduced server overhead by 32% after restructuring routing logic and caching layers.
• Built backend modules in Python for process automation, log parsing and system monitoring,
decreasing manual review hours by approximately 20 hours per month.
• Created secure authentication pipelines with multi layer validation and token management,
improving login success rates by 18% while cutting unauthorized access attempts dramatically.
• Designed and refined over 30+ reusable UI components to maintain a consistent design
language across multiple projects, reducing frontend development time by nearly 45%.
• Improved database performance by optimizing SQL queries, applying indexing strategies and
restructuring data models, cutting some API wait times from 1.2 seconds to under 500ms.
• Guided the transition from a monolithic backend into a modular architecture, enabling
independent service deployments and reducing downtime by over 60%.
• Collaborated directly with project owners to translate feature requests into structured technical plans, producing roadmaps that shortened development cycles by 1–2 weeks per release.
• Integrated third party APIs and internal services, ensuring reliable data flow for payments,
logging and analytics without compromising performance.
• Participated in Agile planning and sprint execution, consistently delivering tasks ahead of
deadlines and helping maintain steady development momentum across distributed teams
