I specialize in security engineering with hands-on experience in web, mobile (Android), API, and network security. My expertise lies in vulnerability assessment and penetration testing, where I excel at identifying critical vulnerabilities and implementing effective remediation strategies. I create secure and scalable systems, driven by a passion for offensive security and bug bounty hunting.
Notably, I developed a secure data recovery system that achieved a 95% data retrieval accuracy and increased efficiency in restoring overwritten data by 40%. Additionally, I built a healthcare decision support system leveraging deep neural networks, significantly enhancing prediction accuracy.

I build the infrastructure production systems run on — and the services that run on it. 4+ years across AWS and Azure, including a live cross-cloud migration during the March 2026 Middle East regional outage with near-zero downtime.
WHAT I DO
☁️ Cloud Infrastructure — AWS and Azure environments built from scratch. Reusable Terraform modules across dev/test/prod. Least-privilege IAM, private networking, and SOC 2 controls built in from day one rather than retrofitted before an audit.
☸️ Kubernetes & Delivery — EKS and AKS design, Helm charts, GitOps with Argo CD using App-of-Apps with auto-sync and self-healing. GitHub Actions pipelines with multi-arch builds and Trivy scanning inside the pipeline, not bolted on after.
📊 Observability — Full instrumentation, not just a dashboard. OpenTelemetry, distributed tracing with Jaeger, Prometheus with custom alert rules, Loki, and Grafana dashboards built for the questions your team actually asks at 3am.
⚙️ Backend & GenAI Pipelines — Python/FastAPI, Django, Node.js. Multi-tenant architecture with schema-per-tenant isolation. End-to-end LLM ingestion on Temporal — batch embedding, retry policies, vector databases — running unattended.
🌐 Networking & Production Firefighting — Routing protocols, VPC and Transit Gateway design, OpenVPN PKI, TLS termination, WAF, DNS, reverse proxies. When something is down and nobody knows why, this is the work I'm best at.
🚨 Backup, DR & Cross-Cloud Migration — Velero for cluster and persistent volume backups, database point-in-time recovery, geo-restore runbooks, and tested restore procedures. Live provider migration when it's needed. I've done this under real outage conditions, not just in a runbook.
RESULTS
- Migrated a client's full production workload from AWS to Azure with near-zero downtime during the March 2026 ME-CENTRAL-1 outage, while the region was unavailable and most teams in it were down for the better part of a day
- Built complete backup and recovery for a production Kubernetes platform — Velero for cluster state and volumes, database PITR, and documented geo-restore runbooks, tested rather than assumed
- Cut manual cloud operations ~95% with a serverless EC2 scheduling platform on Lambda, EventBridge Scheduler, and Terraform
- Reduced order execution latency ~73% on a live automated trading system through Redis caching, async queue processing, and multi-broker integrations
- Architected a multi-tenant SaaS platform on FastAPI and Keycloak SSO with schema-per-tenant PostgreSQL isolation and automated per-tenant provisioning
- Reduced EKS attack surface ~90% with Calico micro-segmentation and Kyverno admission policies, and took the platform to full SOC 2 audit readiness
- Eliminated ~90% of manual infrastructure setup and cut deployment time ~50% with standardized Terraform modules across AWS Organizations
