SUMMARY
Angular developer with 4+ years of commercial experience who was the sole front-end developer on AgriChain Farm,
an enterprise system that runs day-to-day agricultural production for large farms. Improved and extended the software
agronomists, dispatchers, and managers rely on — interactive field maps with routing, season planning that keeps
work out of Excel, and analytics dashboards in place of manual reports — across 40+ screens serving 100+ active
users. Drove a project-wide redesign onto a library of custom reusable components and carried the app through a
major Angular upgrade with zero downtime, working with PM, QA, and backend colleagues in a Kanban flow.

EXPERIENCE

Front-End Developer — Agrichain Nov 2021 – Mar 2026 · Kyiv, Ukraine
Sole front-end developer on AgriChain Farm, an enterprise system for planning and managing agricultural production for
large agribusinesses — used daily by farm managers, agronomists, and dispatchers. 40+ screens, hundreds of
components and modules, 100+ active users.
Improved and extended the interactive field map, reworking it from Leaflet to Google Maps during the Angular
upgrade while keeping the feature live — so dispatchers and agronomists see fields, crop rotation, and
infrastructure in one place instead of tables: fields colored by crop, warehouses and elevators shown as objects,
and routing between a field and an object.
Delivered feature work across many of the product's modules — complex forms, data tables, and validated
create/edit modals built on Reactive Forms — including technology-operation planning with dependent operation,
machinery, and field selections, keeping day-to-day work in the system instead of Excel and paper.
Developed and extended analytics dashboards on ng2-charts / Chart.js (plan-vs-fact, cost structure, and yield) with
filters and Excel export and import, giving management self-serve metrics in place of manual reports.
Drove a project-wide redesign that replaced an outdated, inconsistent UI with a single modern look, building a
library of 10+ custom reusable components for a consistent UX across 40+ screens and faster new-screen delivery
— occasionally collaborating with another developer on some sections.
Reduced UI bugs and user complaints after the redesign and refactoring, and worked with the backend on API
contracts and request optimization to keep the product responsive.
Secured the application with REST API integration and Keycloak for authentication and authorization, enforcing
access through route Guards and HTTP Interceptors, with client state managed in Akita.
Carried the live application through an Angular 7-to-21 migration over roughly a year with zero downtime and
uninterrupted feature delivery, modernizing onto Standalone components and current Angular patterns.
