Experience - Taras Antoniuk

Java Backend Developer (Logistics Platform)

REST API development for a logistics platform according to client business requirements
Implemented order management features for inter-state vehicle transportation, including scenarios where the customer travels by plane while their vehicle is transported to the destination
Backend optimization and refactoring to reduce server response times for mobile driver and customer applications
Implemented truck handover functionality with automatic recording of fuel level, mileage, and cargo inventory at the time of transfer
✓ Impact: Eliminated manual data entry and tracking processes; improved platform performance enabled business to attract more clients and increase operational capacity

Developed faculty workload planning and classroom scheduling system (100+ faculty members, 50+ classrooms, 1000+ teaching hours per semester)
✓ Impact: Automated government workload reporting – reduced processing time from 5 days to 30 minutes (~95% efficiency gain)
Designed and implemented complex PL/SQL queries (MS SQL) for schedule and workload data
Built client-server interactions and unit tests
Managed data synchronization and transfers between multiple databases
Worked with Application Engine, Oracle SQR, Data Mover, Component Interface

Compensation management backend: automated calculation of builder and contractor payments with volume-based compensation, variable bonuses, deductions, and tax computation
Material cost estimation backend: dynamic pricing engine for construction materials with parameter-driven budgeting and cost forecasting
✓ Impact: 60% acceleration in cost estimation process

Developed 10+ backend systems and mobile applications for large-scale enterprise platform across three agricultural organizations.

Platform serving 900+ users (3 organizations × 25 cooperatives × 12 specialists) with automatic recording of all operations from soil preparation through harvest
Functionality: NDVI analysis from drone imagery, automatic detection of pests, plant diseases, and weather damage
✓ Impact: 2 hours daily time savings per user = 360,000 person-hours annually
✓ Impact: Significant yield increase due to real-time response to crop condition changes

Managed 200+ commercial trucks with RTK GPS corrections (0.36m accuracy) for safe crop transportation across 22,300 hectares
Problem: Autumn fog with 10-15m visibility caused loaded trucks to fall into drainage ponds
Solution: GPS-based route planning with audio/haptic alerts for route deviations
✓ Impact: 100% incident prevention (zero accidents after implementation), driver safety and crop preservation

Centralized monitoring of hundreds of equipment units (tractors, seeders, combines) with vibration sensors
Automatic generation of maintenance signals based on maintenance schedules and sensor readings
✓ Impact: Reduced equipment downtime during critical harvest periods, successfully replicated to 2 sugar refineries

Designed and implemented robust data exchange pipelines between multiple databases
Developed RESTful APIs to integrate external systems efficiently
Built logging and monitoring systems to track and audit all data transfer operations
Optimized data workflows for performance and reliability across distributed systems
