Whether you need help automating deployments, improving infrastructure reliability, building data pipelines, or solving production issues, I'm committed to delivering high-quality work on time. Let's discuss how I can help make your infrastructure more reliable, scalable, and efficient.

I am a Site Reliability Engineer with 9 years of experience delivering robust and scalable solutions. My background includes software development and founding startups, where I honed my skills in creating reliable systems that enhance performance and user experience. I specialize in building and maintaining infrastructure that meets high availability standards while optimizing costs. With a master's degree in architecture, I bring a unique perspective to technical challenges, combining creativity with analytical thinking. If you need someone who can streamline operations, improve system reliability, and innovate for growth, let’s connect and discuss how I can help elevate your projects to the next level.

I help startups and small teams ship faster and sleep better — by building rock-solid AWS infrastructure and wiring AI into the ops work that used to eat entire days. A few results from my work as an SRE/DevOps engineer (6 years, AWS-primary): • Cut vulnerability analysis from 60 minutes to under 2 minutes with an AI-augmented workflow • Drove an 80% reduction in vulnerabilities through automated patching • Blocked 4 separate DDoS attacks with zero downtime • Cut manual intervention in CI/CD by 60% • Saved 25% on compute by moving from Cluster Autoscaler to Karpenter • Upgraded a production EKS cluster from v1.23 to v1.28 with zero downtime What I can do for you: • CI/CD pipelines that build, test, and deploy themselves (GitLab CI, Jenkins, GitHub Actions) • AWS architecture, EKS/GKE, Helm and ArgoCD — set up right, or rescued when it's broken • AWS cost optimization audits that find real, dollar-denominated savings • Terraform / Infrastructure-as-Code so your environment is reproducible and reviewable • Cloud security hardening — WAF, secrets management, VPC design, kernel patching • AI-augmented ops workflows that take repetitive SRE toil off your team's plate I work best with founders and small engineering teams in the US, UK, EU, and Australia who need senior infrastructure help without a full-time hire. I'm AWS Certified (Solutions Architect) and I deliver in clearly scoped milestones with async updates, so you always know the status without sitting in a meeting. Most of my engagements are fixed-price packages, so you know the cost up front. Tooling I use daily: AWS, Kubernetes (EKS/GKE), Terraform, Helm, ArgoCD, Karpenter, Docker, GitLab CI/CD, Jenkins, CloudFront, AWS WAF; Python, Go, and Bash; plus Claude and Codex for AI-augmented automation. You can see detailed case studies and my full project history at hemanthakumar.dev If you've got infrastructure that's slow, expensive, fragile, or on fire — send me a message with what's going on and I'll tell you honestly whether I can help and how I'd approach it.

You're building something real, but the ops are held together with duct tape and good intentions. I'm Valeriya, a fractional Chief of Staff who helps non-technical founders get their operations out of their heads and into systems that actually run. I've supported founding teams through the messy middle: tooling, AI adoption, and building the structure that lets you stop being the bottleneck. On the AI side, I start with your business, not the technology. I map where friction lives, then build targeted tools that remove it, not add to it. Whether you want full AI-native operations or just a few high-leverage automations, we go as deep as makes sense for where you are. What I bring: - 5 years in systems reliability at Morgan Stanley - Active fractional CoS engagements with early-stage startups - Entrepreneurial experience (4 years of running my advisory business) - MBA (Valedictorian, HEC Montréal) - Fluent in both business strategy and technical implementation If your business is growing faster than your systems, that's exactly where I work best.
