You will get a legacy application rebuilt or modernized into a fast, stable platform


Project details
You will receive a clear and practical evaluation of your current application with recommendations you can immediately use. I specialize in taking older or unstable systems and giving people a solid understanding of what is working, what is not, and what it will take to bring everything up to modern standards.
I recently rebuilt a very old platform that serves thousands of users and stores over half a million records. It had broken authentication, corrupted data, performance issues, and no documentation. I rebuilt it from the ground up and brought it back to life. I bring the same attention to detail to every project I work on.
Depending on the tier you choose, you will receive a short audit, a full modernization review, or a complete rebuild and migration plan with recommended phases and timelines. Everything is delivered in a clean, easy to read PDF that you can share with your team or any decision makers involved.
If you want clarity before committing to major development work, this service gives you exactly that.

About Heather
US Based Senior Full Stack and DevOps Engineer - Java Node.js Angular
Gentry, United States - 4:08 am local time
I rebuilt a failing 1990s platform (K9data.com) end to end and relaunched it as a modern production system (k9-data.org) in under 6 months. Now serving thousands of users and over 500,000 records.
The original site had no working logins, corrupted data, and an unmaintainable codebase. I rebuilt everything end to end:
Full data migration, fresh architecture (Node.js, Angular, PostgreSQL, Docker), role-based permissions with audit logging, query optimization, CI/CD, and automated backups.
This is what I bring to your project:
Fast diagnosis, clean architecture, ownership from database to deployment, and clear communication so you're never left guessing.
Background:
10+ years building secure, scalable systems. Enterprise experience. Prior security clearance, I build with data integrity and discretion by default.
I’m used to jumping into unfamiliar stacks, debugging quickly, and knowing when to repair vs. rebuild.
Tech:
Node.js • Angular • PostgreSQL • AWS • Docker • Kubernetes • CI/CD • OAuth • REST APIs
Best at:
Legacy modernization • Performance optimization • Data migration • SaaS architecture (subscriptions + RBAC) • Fast delivery without breaking things.
U.S. based. Responsive. Production quality code from day one.
If you need someone who can fix what’s broken and ship what your business actually needs, let’s talk.
