Project history

Senior DevOps Engineer

Influence Pro Services
Sole infrastructure lead across AWS and DigitalOcean: set architecture standards, ticket triage and ownership policy, and on-call practices. Architected and built multi-cluster Kubernetes (dev and production) from scratch via Terraform, API and CLI automation. Moved cluster and service access to a VPN-first, zero-trust model. Owned CI/CD architecture end to end (Bitbucket Pipelines); led an audit of 30+ repositories. Led response to an upstream certificate rollover on production NGINX Gateway Fabric gateways. Built Prometheus alerting and Grafana dashboards with custom health metrics. Administered HashiCorp Vault policies and rolled out vulnerability scanning and static security analysis.

System Development Engineer

Amazon
Owned reliability and architecture for production services on ECS, Lambda, DynamoDB and S3. Built automated load- and chaos-testing frameworks into the deployment pipeline. Ran large-scale distributed load tests against AWS-hosted services. Designed chaos scenarios that exposed failure modes in distributed systems. Built CI/CD automation for infrastructure and service deployments. Drove cost optimization on production AWS workloads and ran security hardening and patching processes. Reviewed code and architecture for the wider team.

Senior Performance QA Engineer

SQUAD
Set performance testing strategy across several applications and built a reusable load-testing framework adopted by multiple teams. Worked with developers to fix performance issues before release and mentored engineers on performance methodology.

Senior Performance QA Engineer / Team Lead

PUMB (First Ukrainian International Bank)
Led the bank's performance testing team: planned workload, set priorities and reviewed test designs and results. Owned performance strategy for core banking and customer-facing systems, defining load models, SLAs and release go/no-go criteria. Diagnosed bottlenecks across application, database and infrastructure layers. Reported performance risks and capacity findings to engineering managers and business stakeholders. Mentored and onboarded performance engineers.

Performance QA Engineer / Performance Analyst

PUMB (First Ukrainian International Bank)
Designed and ran load, stress and endurance tests for banking applications and integrations before production releases. Built and maintained test scripts and environments, and analysed response times, throughput and resource usage to pinpoint degradations. Set up monitoring for test runs and produced reports with findings and tuning recommendations.

Earlier Roles

EPAM Systems, Alfa-Bank Ukraine, PrivatBank
Performance testing, systems monitoring, database administration and payment-terminal infrastructure in banking environments.
