Work experience

Java-розробник

from 08.2018 to 03.2026 (7 years 8 months)
Apple, Sunnyvale (IT)

Architected and delivered end-to-end software solutions aligned with strategic enterprise
requirements, spanning microservices design, core business logic implementation, comprehensive
automated testing, and cloud deployment. Proactively optimized application throughput, resolved
critical production incidents, and engineered high-reliability systems for core customer-facing
platforms.

Responsibilities:
• Architected and developed a centralized platform service powering Apple's customer-facing and
corporate LLM applications, featuring robust conversation management, a RAG layer for
contextual response augmentation, and plug-and-play integration for foundation models
(Mistral, Gemini, BGE3). Engineered real-time data ingestion pipelines using Apache Kafka to
continuously enrich the RAG layer and optimize output accuracy.

• Designed and implemented the high-throughput AppleCare Health Portal utilizing Spring
WebFlux reactive framework, enabling secure access to customer support files and audit logs
for internal advisors and government compliance auditors. Built end-to-end HIPAA-compliant
architecture incorporating PHI/PII data encryption, granular role-based access control (RBAC),
and immutable audit logging across all data interactions.

• Engineered PSD2 and GDPR compliance solutions and spearheaded international expansion
for the Support Payments Portal - a high-availability, customer-facing web application operating
in 60+ countries processing 6,000+ daily transactions across credit/debit cards, Apple Pay, and
digital wallets.

• Architected and executed cloud migration strategies for Customer Systems applications to AWS (EKS, S3, IAM, CloudFormation).

• Designed and configured automated CI/CD pipelines utilizing
Jenkins, Docker, Helm, and Spinnaker to streamline containerization and zero-downtime
Kubernetes deployments.

• Managed end-to-end network architecture, load balancers, firewall policies, and traffic routing
configurations to guarantee continuous availability and low latency for Customer Systems
applications.

• Designed and developed high-performance RESTful APIs across multiple corporate initiatives,
strictly enforcing REST architectural standards and optimizing client-server payload delivery.

• Engineered automated UI and integration testing frameworks with external API service
virtualization utilizing WireMock to accelerate deployment velocity.

• Implemented resilient asynchronous task schedulers and background processing workflows,
significantly increasing enterprise system throughput and operational efficiency.

• Established real-time observability frameworks by creating custom Splunk dashboards and
proactive monitoring alerts, drastically reducing Mean Time to Detect (MTTD) and resolving
production incidents.

• Conducted extensive load testing analysis using JMeter and targeted backend performance
tuning, eliminating bottlenecks and optimizing resource utilization across key microservices.
