Led high-impact initiatives across identity, access management, secrets management, and security infrastructure, building systems that protect authentication, authorization, and sensitive data at scale in a zero-trust environment.

• Designed and built identity and access management (IAM) systems, including SCIM-compliant provisioning, lifecycle automation, and fine-grained authorization models powering enterprise integrations with external Identity Providers.

• Played a key role in the design and adoption of Service Accounts, driving 35% growth in secure automation usage across CI/CD and cloud-native environments.

• Architected fine-grained access control using Object-Data Access (ODA/OD) models, enabling secure permissioning across distributed systems while enforcing least-privilege principles.

• Designed and implemented end-to-end encrypted (E2EE) services, leveraging symmetric and asymmetric cryptography, hashing, key derivation, and the Noise Protocol to secure data and transport layers.

• Led work on secrets management and secure credential handling, including secure storage, access enforcement, rotation workflows, and service-to-service authentication for cloud-native and CI/CD environments.

• Delivered Confidential Computing solutions using AWS Nitro Enclaves, contributing to zero-trust architecture initiatives and secure workload isolation.

• Built and operated security-critical distributed systems in Go, optimized for high throughput, fault tolerance, and reliability using Go’s native concurrency primitives.

• Contributed to security-focused developer tooling such as the 1Password CLI, Connect Server, and integrations enabling secure secrets usage across cloud-native and CI/CD pipelines (1Password Terraform Provider, Kubernetes Operator, Helm Charts, Pulumi Provider, SDKs)

Contributed to the design and development of a greenfield SaaS platform, taking the product from early concept to production by building scalable backend services, cloud infrastructure, and developer workflows.

• Designed and implemented a microservices-based architecture, translating business requirements into reliable, production-ready systems.

• Built and operated backend services using Node.js, backed by PostgreSQL and message queues, with a focus on reliability and scalability.

• Introduced and maintained CI/CD pipelines, enabling automated testing, deployment, and safer iteration across services.

• Worked across the stack — backend services, APIs, and supporting infrastructure — gaining hands-on experience with cloud-native system design on AWS.

• Collaborated closely with product and engineering stakeholders in a fast-moving startup environment, developing strong ownership and system-level thinking.

I worked as a full-stack developer at ELEKS.

Our customer is the largest delivery company in the UK. We help to improve their business by providing more new applications and solutions.

In 2019 I was leading a brand new project. The technology stack was React Native, Express.js, Firebase, Google Cloud Platform (Cloud SQL, Pub/Sub). I worked on the frontend and backend parts along with 2 frontend developers and 2 QA and 1 QA automation engineers.

This app improved the reliability of the delivery service.

In 2020 I worked as the backend developer on another one project along with 10+ frontend and 5 backend developers. The technology stack as usual Express.js, Google cloud platform (Spanner, GAE, CF, Pub/Sub).

I took part in the development of key services in the client's infrastructure which allowed us to increase the company's revenue up to 40% in 2020.

I worked in the health care area where I developed a mobile application and backend for it. It was used by several clinics in the USA.

I was a part of the team that developed a mobile banking application for one of the largest companies in Europe which offers hardware and software for the banks.

I have a role of a full stack engineer.

I took part in a several small projects, and worked with several startups, on long term bases.
