Most modernization projects fail in the gap between people who understand the old system and people who know the new stack. Legacy Fade lives in that gap.

That means being able to read the fifteen-year-old VB.NET form, trace the stored procedure behind it, find the directory group that controls who can open it, fix the pipeline that ships it, and then replace it so quietly that the people using it only notice it got faster.

The work comes from a career spent where downtime is expensive: manufacturing systems, regulated data, and most recently years of principal-level DevOps and platform engineering across an entire application portfolio. Desktop apps, web portals, APIs, partner integrations, databases, scheduling, identity and the servers under all of it.

Every engagement gets that full picture, not a hand-off between specialists.

Path

How we got here.

  1. 1995

    Manufacturing at global scale

    Two decades building supply chain software and factory automation, where an hour of downtime has a dollar figure attached.

  2. 2015

    Regulated data

    Encrypted, audited data platforms where security and traceability are requirements, not features.

  3. 2017

    Principal DevOps and platform engineering

    Leading a full-portfolio migration off an end-of-life framework, building the pipeline library an organization ships through, and owning apps, integrations, data, identity and servers.

  4. 2026

    Legacy Fade LLC

    Bringing that same playbook to companies that need their legacy software modernized without a big-bang rewrite.
