Gregory Zarochentsev

Tasked with delivering precise and reliable solutions by applying a customer centric strategy that affect 1M+ clients * Successfully developed library used by 300+ developers and implemented it in over 100+ projects, resulting in a reduction to test creation time and code volume by 5x without compromising stability and code coverage * Refactored monolith app by implementing NX DDD architecture and microfrontends to simplify development and independent CI/CD

Successfully orchestrated end-to-end development of a scientific portal, providing instruments for rapid peer review and publication of scientific articles, as well as hybrid format conference organization * Completed MVP within three months, spearhing the project from initial conception to first version release * Designed and developed a proprietary microservice architecture that reduced the time needed for implementing new modules from few months to weeks

Led the development of an AgroTech online portal allowing centralized farm monitoring (crops growth analysis, water consumption, soil and weather conditions, equipment state) and real-time danger alerts * Implemented machine learning models for crop forecasting, resulting in up to 30% increased crop size and up to 20% cost reduction in irrigation over a 4-month season * Transferred the project from multiple virtual machines to Docker and GitLab CI/CD, and integrated database migration system

Developed core modules (DB design, Backend and Frontend) including SSO, RBAC, JWT auth, robust logging and critical error notification system, and account module for individual and corporate users * Managed project management efforts to facilitate discussions and negotiations with business stakeholders that drive recommendation consensus on deliverables * Digitized critical business logic from Excel to an optimized system, resulting in a remarkable 12x increase in the customer base

* Collaborated on database design, creating models and translating all queries from pure SQL to SQLAlchemy in uniform style (including PostGIS) * Digitized scientific models from Excel into Python microservices, implementing efficient algorithms and data structures to ensure optimal calculations * Contributed to code reviews and participated in team discussions to improve code quality and maintainability
