Work experience

Front-end програміст

from 04.2024 to now (2 years 8 months)
Waites, Дистанційно (Машинобудування)

Project: Internal Asset Configuration Platform

• Setup the frontend architecture, project structure, development conventions and core configuration from scratch for a greenfield product, taking the application from initial setup to production in just 3 months.
• Built a schema-driven configuration system supporting 4 variable types with dynamic controls, type-specific validation and shared-variable propagation, plus 3 cascading filters that reduced manual selection complexity and making asset setup faster and more consistent for installation teams.
• Designed and deployed an internal UI Kit library of 20+ reusable components shared across 2 Waites applications, standardising interaction patterns and accelerating cross-project delivery and time-to-market.

Project: Full-Service Predictive Maintenance Platform

• Completed migration of a legacy jQuery application (200+ enterprise customers, 500,000+ installed sensors) to React, modernized frontend architecture, replaced fragmented state management with
modular, predictable Zustand stores.
• Built a new analytics experience with 6 interactive Highcharts visualizations, giving customers clear ROI visibility as well as key equipment trends.
• Eliminated scrolling lag in a core operational table by tracing excessive React re-renders and optimising the rendering flow, reducing redundant renders by ~80% for smoother data-heavy interactions.
• Reimplemented core operational data-management workflows into more scalable and maintainable interfaces, systematically improved responsive behaviour across the application down to 800×600 resolution.
• Pioneered the use of Typescript for new features, introduced cross-code reviews across the frontend team.

Front-end програміст

from 10.2019 to 03.2024 (4 years 6 months)
Intellias, Дистанційно (IT)

Worked across multiple products for private aviation client VistaJet, contributing to several long-running enterprise applications and greenfield solutions. Expanded ownership beyond frontend development into Backend-for-Frontend (BFF) implementation, performance optimization, observability, technical modernization, production support, release delivery, and UI/UX solution design

Project: Private Aviation Flight Pricing & Document Automation Platform for Sales team. Primary / longest-running project

• Served as the primary frontend developer, owning feature delivery from requirement clarification and UI/UX design through React/BFF implementation, release and production support.
• Independently migrated all core frontend functionality from Javascript to Typescript (coverage from 0% to 70%) and introduced automated GraphQL type generation, strengthening frontend-API contracts and reducing manual DTO synchronization.
• Redesigned the resource-intensive Similar Flights workflow by moving computation from database queries into the BFF, reducing response time from ~20-30s to 5-10s.
• Automated the static document update process to remove developer involvement, enabling business stakeholders to perform updates in minutes instead of a ~4-hour release cycle.
• Extended end-to-end tracing (Jaeger, later Datadog) for frontend and BFF across Kafka-based workflows, introduced Datadog RUM, integrated Salesforce CRM, optimised Prisma data-access patterns and built reusable Liquid-based generation flows for 8 client-facing PDF/email templates.
• Redesigned the application startup data flow with parallel and progressive loading, cutting Time-to- Interactive (TTI) from ~10-15s to 3-5s so Sales users could begin working sooner.

Project: Airport mismatches for Sales team

• Delivered the greenfield Airport Mismatches application from scratch to production in 4 months
• Independently developed the BFF layer with autogenerated GraphQL types for BFF and frontend applications, identified and addressed core table performance bottlenecks.
