    Decision it supports

    Which workloads to move first, in what order, and at what risk.

    • Migration scope and risk assessment
    • Working serverless implementation for the agreed workload
    • Terraform modules, alarms, and dead-letter handling

    Offer 02

    AWS cost and reliability review

    Decision it supports

    Where to cut cost safely and which reliability gaps to close.

    • Cost drivers by service and account
    • Architecture findings ranked by impact and effort
    • Right-sizing and savings-plan notes where relevant

    Founder, Thank You Welcome LLC

    • AWS Certified Solutions Architect – Associate
    • AWS Certified Developer – Associate
    • AWS Certified Cloud Practitioner
    LinkedIn profile

    I have spent 10+ years building cloud-native and event-driven systems, including leading TypeScript modernization and real-time pipelines at Southwest Airlines and serverless data pipelines at TickerTags.

    I started Thank You Welcome LLC to give government and commercial buyers direct access to that experience: no account managers and no hand-offs to a bench you never met. I scope the work, build it, and document it so your team can run it.
