With over 15 years of experience in software engineering and technology leadership, I combine deep hands-on expertise with a strategic mindset to help organizations design, scale, and secure modern technology systems. My career began with a focus on Java and full-stack mobile and backend development, gradually expanding into Kotlin, AWS, and Kubernetes as my work evolved into cloud-native ecosystems.
Over the past decade, I have built and led high-performing engineering teams, guided product strategy, and taken full ownership of technical roadmaps as Engineering Manager, Head of Engineering, and CTO. This dual track — strong technical execution and cross-functional leadership — allows me to contribute both as a senior engineer and as a strategic partner in technology-driven organizations.
Core technical expertise:
Backend Development: Kotlin, Java, Spring Boot, REST, GraphQL, Hibernate, Postgres.
Cloud & Infrastructure: AWS (EKS, S3, SQS, CloudWatch, Lambda, IAM), Kubernetes, Terraform, CI/CD pipelines.
Architecture & Scalability: Event-driven systems, microservices, API design, observability (Prometheus, Grafana).
Cybersecurity: Secure application design, threat modeling, compliance-aware architecture.
Frontend & Mobile (earlier career): Android development, cross-platform integrations.
Leadership & strategic skills:
Technology Strategy: Defined long-term architecture roadmaps aligned with business goals.
Cross-functional Leadership: Collaborated closely with product, design, marketing, and sales to ensure technology delivered customer and business value.
Team Building & Mentorship: Hired, coached, and scaled engineering teams across multiple startups and high-growth environments.
Product-centric Approach: Actively led design sprints and product workshops, ensuring technical decisions supported user experience and commercial impact.
Operational Excellence: Streamlined processes to reduce costs, increase delivery speed, and improve system reliability.
Throughout my career, I have acted as a bridge between business and technology — helping non-technical stakeholders make informed decisions while ensuring engineering teams are empowered to deliver. Whether designing a secure, scalable cloud architecture, modernizing legacy systems, or bringing a minimum viable product to market, I bring both the strategic vision of a CTO and the hands-on expertise of a senior engineer.
I thrive in environments where technology is a key driver of growth — from fintech and mobility to SaaS and platform products. My passion lies in solving complex problems, simplifying architecture, and building systems that can grow with the business.
Today, I focus on providing high-impact contributions as a Senior Backend Engineer, Cloud Architect, or Fractional CTO, supporting organizations that need both immediate technical execution and long-term strategic guidance.
