Expert-Vetted on Upwork (Top 1% of security professionals). If you're building on the cloud and want to find the security gaps attackers would exploit — before they do — I can help. I’m a cybersecurity consultant and founder of Exfiltra, helping startups and enterprises secure their applications, cloud infrastructure, and DevOps pipelines. I have worked with organizations generating $6B+ in annual revenue and helped companies strengthen security across cloud environments, applications, and compliance programs. I personally lead security engagements and, when needed, bring in specialists from my team at Exfiltra to support larger or complex projects. Most clients hire me when they want to: ✔ Secure Azure / AWS / GCP environments ✔ Perform professional penetration testing ✔ Implement DevSecOps and secure CI/CD pipelines ✔ Prepare for SOC 2, ISO 27001, HIPAA, FedRAMP, or CMMC ✔ Improve security posture using industry frameworks CORE EXPERTISE AZURE & CLOUD SECURITY • Azure security architecture reviews • Microsoft Defender for Cloud & Sentinel • Identity security (Entra ID / Conditional Access) • Cloud configuration reviews and CIS Benchmark hardening APPLICATION SECURITY & PENETRATION TESTING • Web application penetration testing • API security testing • Mobile application security testing • Network and cloud penetration testing • Assessments aligned with OWASP Top 10 and OWASP ASVS DEVSECOPS & SECURITY AUTOMATION • Secure CI/CD pipelines (Azure DevOps / GitHub Actions) • Infrastructure as Code security (Terraform / Bicep) • SAST and DAST integration in pipelines SECURITY TOOLS • Snyk • Semgrep • OWASP ZAP • Burp Suite • Wazuh • CrowdStrike • Microsoft Sentinel AI & LLM SECURITY • AI application threat modeling • Prompt injection and model abuse testing • Secure architecture for AI-powered applications WHY CLIENTS WORK WITH ME • Upwork Expert-Vetted (Top 1% of freelancers) • Founder of Exfiltra – a cybersecurity services company • Supported by a team of security specialists for larger engagements • Contributor to OWASP ZAP • Experience securing environments for organizations generating $6B+ in revenue • Background in both software engineering and cybersecurity • Security research involving organizations like the U.S. Department of Defense NOT A GOOD FIT IF • You want to hack or recover social media accounts • You want enterprise-grade security but are not willing to invest in it If your goal is to build secure systems instead of reacting to breaches later, feel free to invite me to your job or send a message describing your project.

Your infrastructure breaks at 2 AM. Your deploys take 45 minutes. Your AWS bill climbed 40% and nobody can explain why. I fix all three - and I've done it 100+ times on this platform. Former SRE Lead at Yellow AI (100M+ users, AWS + on-prem). Now I run Skybyte, a DevOps and cloud consulting practice focused on startups and mid-market teams that need senior infrastructure work without the senior hire. What 61+ Upwork jobs and a 100% Job Success Score actually look like: Cloud cost optimization - cut AWS/Azure/GCP spend by 40-60% through right-sizing, Reserved Instances, spot fleets, and architecture cleanup. Not guesswork; I run the cost audit, build the dashboard, and hand you the savings. Kubernetes migration and management - moved production workloads to EKS, AKS, and self-managed clusters on Hetzner. Helm charts, ArgoCD GitOps, zero-downtime cutovers. I've handled clusters running 200+ pods and clusters running 6. CI/CD pipeline engineering - GitHub Actions, GitLab CI, Azure DevOps Pipelines, Bitbucket Pipelines. Took teams from 45-minute manual deploys to sub-5-minute automated releases with rollback built in. Infrastructure as Code with Terraform - full AWS, Azure, and GCP environments defined in Terraform modules. State management, drift detection, and PR-based infrastructure reviews that your team can maintain without me. DevSecOps and compliance - SOC 2 infrastructure from scratch, cloud security audits, Cloudflare WAF and DDoS protection, network security architecture, and DPDP-aligned data handling. I've built the controls and written the documentation auditors actually accept. Monitoring, observability, and SRE - Prometheus, Grafana, OpenTelemetry, Datadog, PagerDuty. Full observability stacks that catch failures before your users file tickets. I set up SLOs, runbooks, and on-call workflows. Beyond core DevOps - SSO/SAML integration, n8n workflow automation, MLOps pipelines, Docker deployments on bare metal and VPS, GCP Cloud Run serverless, and technical documentation your team won't ignore. I work best with funded startups burning money on cloud, engineering teams stuck in deployment hell, and companies scaling past the point where one developer can manage the infrastructure part-time. Stack: AWS (EKS, EC2, Lambda, RDS, S3) · Azure (AKS, DevOps, AD) · GCP (GKE, Cloud Run) · Kubernetes · Helm · Terraform · Docker · GitHub Actions · GitLab CI · ArgoCD · Prometheus · Grafana · OpenTelemetry · Datadog · Cloudflare · n8n Not a "set it up and disappear" contractor. I document everything, train your team, and build systems designed to run without me and scale.
