Current Project: Platform Engineering & Hybrid Cloud
I am currently architecting a proof-of-concept for an advanced AWS EKS platform with hybrid nodes, designed to unify container management across AWS and on-premises data centers. This involves creating a scalable solution for modernizing legacy applications and developing the core strategy for networking, security, and operational consistency between the cloud control plane and on-prem worker nodes.
Previous Project: SRE for an AI/Security Platform
As the sole SRE, I built a secure, multi-cloud infrastructure from the ground up. Key achievements include:
GenAI & Performance: Slashed GenAI operational costs by over 99% and reduced model latency by 80% by migrating from Azure OpenAI to a self-hosted LLM on AWS GPUs. Scaled the platform to handle over 100,000 daily requests.
Cloud Architecture & DevOps: Designed the entire multi-cloud (AWS/Azure) infrastructure using Terraform. Architected and optimized a CI/CD pipeline for a complex monorepo, cutting build times by 30% and runner costs by 90%.
Security & Compliance: Led the technical implementation and hardening efforts to achieve ISO 27001 and SOC 2 compliance, successfully clearing all VAPT assessments.
Strategic Cost Optimization: Drove a sustained 20% reduction in average monthly cloud spend. Saved over $500/month by replacing expensive managed services (VPN, Cache) with performant, self-hosted alternatives.
Data & Observability: Built a ClickHouse-based analytics pipeline to process over 30TB of data. Overhauled the monitoring stack, cutting costs by 50% and reducing alert noise by 90%.
