Key Services
AWS Cloud Engineering
I build secure, scalable, and observable cloud environments using AWS-native tools, Infrastructure as Code (CDK, CloudFormation), and modern engineering practices. My pragmatic approach helps customers move fast without compromising on reliability or security.
Agentic AI Systems, ChatBots, and Generative AI
I design and build intelligent, secure chatbot and AI solutions, combining deep technical understanding with practical experience in building robust cloud-native systems. My solutions fit seamlessly into your broader technology landscape, supporting your data protection and compliance needs.
AWS Technology Operations
With deep knowledge of the AWS Well-Architected Framework and hands-on experience in AWS Managed Services (AMS), I help you establish robust operations: monitoring, incident management, change enablement, and cost governance. My solutions enhance service reliability, performance, and financial efficiency.
Application and Infrastructure Security
I bring a proven track record in reducing organizational risk through structured risk remediation programs and a deep understanding of architectural trade-offs. With practical, hands-on experience performing threat modeling — including approaches like STRIDE — I help identify and proactively remediate risks early in the design lifecycle, shifting security left. My approach blends nuance and engineering rigor to protect your systems while enabling your business to thrive.
Cost Optimization and Cloud Financial Management
Cost is fundamentally driven by architecture — your costs reflect the systems you build. My engineering experience enables me to go beyond the basics of Reserved Instance and Savings Plan purchases, and beyond "low hanging fruit" identified by automated savings tools. I analyze your architecture deeply to find hidden inefficiencies and optimizations throughout the entire technology stack, uncovering savings opportunities that typical approaches can miss. This allows me to design cost optimization strategies that align technical excellence with financial efficiency.
