Built a production RAG pipeline on AWS Bedrock (Anthropic Claude, Amazon Titan) with pgvector semantic retrieval, multi-provider LLM routing, and source-attributed responses, designed for financial document Q&A at scale. Deployed and operated EKS clusters with Istio service mesh and Kiali observability - implemented canary and blue/green traffic shifting via Argo Rollouts with automated rollback o

At Fiserv, I played a key role in streamlining internal operational workflows by converting fragmented tribal knowledge into structured, audit-ready documentation and actionable training content. This improved cross-team clarity, accelerated onboarding, and reduced operational friction during handovers.

On the application side, I modernized both the JavaScript frontend and the Django backend supp

As a Network Development Engineer II, I focused on building large-scale automation and tooling that removed operational friction and unlocked new capacity for Amazon’s global datacenter network. I engineered multiple internal solutions for L7 that eliminated repetitive manual work, improved reliability, and accelerated overall deployment velocity.

I built a zero-risk, touchless pre-provisioning w

As a Network Deployment Engineer I, I contributed to Amazon’s large-scale datacenter growth by delivering high-impact projects under the ASD (Aggregation Scaling & Deployment) program. I played a key role in Spine Scaling, creating brand-new deployment templates that did not previously exist, enabling end-to-end build-outs of additional spine capacity and significantly increasing datacenter throug

As an On-Prem Network & Systems Engineer at Parker Hannifin, I delivered several high-impact infrastructure modernization projects across UK and EU sites.

I led the migration of multiple plants to the UK Datacenter, consolidating legacy servers and Active Directory domains. This reduced authentication latency by over 40% and eliminated repeated login failures across production environments. I als

As a Security Consultant, I worked across enterprise environments implementing and optimizing Trend Micro security solutions, with a strong focus on IDS/IPS, endpoint protection, and threat-detection strategies. I collaborated with security and infrastructure teams to assess vulnerabilities, design mitigation plans, and ensure continuous protection of business-critical systems.
