Implemented bot protection and security improvements for checkout/inventory integrity. Led 15–30 developers (in-house + vendors); predictable releases and on-call. Stack (select): PHP/Magento, Node.js, Golang, Vue, MySQL, MongoDB, Elasticsearch, Redis, Kafka, Docker, Kubernetes.

Led a small cross-functional team delivering UK edtech/fintech platforms (Vivomiles, Pocketmoney) and several mobile-facing APIs. Drove system design: service boundaries, data models, async processing (e.g., RabbitMQ/Beanstalk) to improve throughput and reliability. Established delivery basics — coding standards, CI & automated tests (PHPUnit/Selenium) — to stabilize releases. Owned API versioning and auth patterns for mobile integrations; improved developer experience and maintenance.

Built and led the engineering team; coordinated IT-adjacent functions (SEO/Marketing/Support) around delivery goals. Re-architected the EST.ua platform (v2.0): PHP stack, DB schema, and caching strategy for content delivery. Introduced lightweight SDLC practices (code review, branching, deployment checklists) to reduce production risk. Set up basic monitoring and incident handling to shorten time-to-resolve.

Directed the development process for price-comparison products (Price, Sravni); aligned architecture with product roadmap. Defined core backend components (data ingestion, search/index, reporting) and coding standards across the team. Coordinated delivery with stakeholders; improved predictability of releases.

Managed end-to-end delivery for analytics/PPC components; balanced scope, quality, and timelines. Designed and maintained server-side modules and PPC logic; ensured performance and correctness under load. Streamlined maintenance processes and handover documentation.

Built CRM, dashboards, mailer, graphs, and PPC modules for HitDynamics; front- and back-end contributions. Designed databases for several projects; improved query performance and maintainability. Implemented server-side integrations and deployment routines.

Developed an online record-keeping system: backend APIs, admin UI, and DB schema. Introduced basic coding standards and release notes to ease support. Collaborated with stakeholders to clarify requirements and reduce rework.
