Lead Platform Engineer · Data Platform Architect · Distributed Systems

I design and build engineering and data platforms that enable teams to develop, deploy, and scale applications, analytical services, and data-driven products safely and efficiently.

I help transform complex infrastructure into reliable, manageable, and reproducible platform products.

About Me

I am a Lead Platform Engineer and Data Platform Architect with more than 20 years of experience in IT.

I work at the intersection of platform engineering, distributed systems, data infrastructure, security, and production operations.

I specialize in platforms that have moved beyond the experimental stage: multiple teams begin relying on them, the cost of change increases, and reliability, security, access control, and operational reproducibility become critical.

I combine architectural responsibility with hands-on engineering. I design solutions, build prototypes, integrate components, automate operational processes, and participate directly in bringing systems into production.

Areas of Expertise

Platform Engineering

I build internal engineering platforms and self-service capabilities that reduce teams’ dependence on manual infrastructure operations.

Data Platform Architecture

I design platforms for collecting, storing, processing, and serving data for analytics, applications, and AI workloads.

Security and Access Control

I design identity and access-management models, including RBAC, Policy as Code, and fine-grained access control for data and infrastructure.

Reliability and Operations

I design observability, operational processes, and architectures that remain reliable under failures, increasing workloads, and continuous change.

Infrastructure Automation

I automate infrastructure provisioning, configuration, delivery, and operations using Infrastructure as Code and GitOps practices.

Typical Challenges

I am particularly effective when:

  • a prototype or internal project needs to become a production platform;
  • multiple teams begin using the same platform;
  • manual operations limit development speed;
  • changes become expensive and risky;
  • architecture formally exists, but decisions are still made situationally;
  • there is no consistent model of access or ownership;
  • reliability, auditing, and security requirements are increasing;
  • data infrastructure needs to support analytics and AI workloads.

In these situations, the core problem is rarely the choice of a specific technology. More often, it is the loss of manageability, architectural context, and clear system ownership.

Approach

I view architecture not as a collection of diagrams, but as a system of deliberate technical and organizational decisions.

I focus on:

  • clear component and ownership boundaries;
  • reproducible deployment and operations;
  • automation of repetitive processes;
  • system observability;
  • safe and controlled changes;
  • reducing dependency on individual specialists;
  • enabling teams to evolve the platform without constant manual intervention.

My goal is not simply to introduce another technology. It is to build a system that teams can operate, understand, and evolve over the long term.

Technical Expertise

Data and distributed systems: Kafka, Debezium, Trino, Spark, Airflow, S3, MinIO, Lakehouse

Platform and infrastructure: Kubernetes, Docker, Terraform, Ansible, Helm, CI/CD, GitOps

Identity and security: Keycloak, Active Directory, OAuth2/OIDC, RBAC, OPA, Policy as Code

Observability: Prometheus, Grafana, Loki, Mimir, OpenTelemetry

Software engineering: Python, Go, Java, SQL, REST APIs, distributed systems architecture

Professional Focus

I am currently considering hands-on roles such as:

  • Lead Platform Engineer;
  • Data Platform Architect;
  • Platform Architect;
  • Lead DevOps / Platform Engineering;
  • Technical Lead for a platform engineering function.

I am most interested in complex data, AI, and cloud-native platforms where architectural responsibility is combined with hands-on engineering and production ownership.
