Lev Maltsev

I help engineers, tech leads, and organizations build scalable, reliable, and cost-efficient systems. With 10+ years in software engineering — from fintech and e-commerce to streaming giants like Hulu and Disney+ — I’ve led multi-million-dollar cloud migrations, designed observability platforms that cut costs by millions, and driven SRE practices that halve incident recovery time. 💡 What I can help you with • Building scalable cloud-native architectures (AWS, Kubernetes, high-load systems) • Designing and implementing observability with OpenTelemetry, Grafana, and modern monitoring stacks • SRE mindset & practices: SLIs/SLOs, incident management, reliability culture • Leading cross-functional teams and navigating complex tech transformations • Career growth: from developer → tech lead → solution architect → engineering leader 🌟 Why work with me? I combine hands-on technical depth with leadership experience. I don’t just give theory — I share battle-tested frameworks and real-world lessons from operating some of the world’s most complex and high-traffic platforms. My mentoring style is direct, actionable, and tailored to your specific challenges.
