You will get a modernization plan for your legacy PHP + JavaScript app
Project details
Every legacy codebase hits a point where upgrading feels riskier than leaving it alone. PHP 5 or 7, Vue 2, jQuery, dependencies frozen since the last person who understood them left. You know it needs to move. The hard part is sequencing the migration without taking production down with it.
I map the path. You get a phased roadmap: what to upgrade, in what order, and why, with risk and effort spelled out per step, so the system stays shippable the whole way.
I've written JavaScript for 25+ years, and I've lived this migration from the inside: a decade on two multi-tenant platforms serving 116 colleges, including a jQuery-to-Vue conversion run page by page, for years. Three costs decide a migration: reversing, staying, and the interim route. The interim route is the one that goes unpriced. Your roadmap prices it.
When the plan's ready, I can build phase one. Most consultants hand you a strategy deck and wish you luck. I write the roadmap, and I can write the migration, so the plan doesn't rot in a Google Doc.
I keep my workload deliberately light, so the roadmap gets undivided focus. Ask me for a start date before you buy, and you'll get a straight answer.

About Tamara-TJ
Senior Full-Stack Engineer | 25+ Yrs JavaScript | Architecture Audits
San Diego, United States - 1:46 pm local time
Most of my work starts the same way: a fixed-scope review. I read your architecture or your legacy codebase, tell you what's actually wrong, and hand you a ranked plan to fix it. Those are set-price projects in my catalog below, so you don't sign up for open-ended hourly work just to find out if we're a fit.
I've built and modernized web platforms in education, e-commerce, nonprofit, and enterprise. I get pulled into complex domains, messy workflows, legacy systems, multi-role permissions, long-lived data, and I stay long enough to make them stable.
What that looks like in practice:
• Ten years on two multi-tenant SaaS platforms for the California Community Colleges system: 116 colleges, 2,000+ users, and 300,000+ submissions between them, architecture through release to production.
• Single sign-on across all 116 colleges: Keycloak, SAML federation, and an MFA flow. I led 15 developers across 4 organizations for a year to ship it, because sign-in is where every user meets the system.
• With the data team, maintained and updated the AWS data warehouse and supported the ETL pipelines feeding its 20+ projects, from ingest through S3 into Redshift. Built the reports in JasperReports and designed the dashboards in Apache Superset.
• WCAG 2.2 / ADA / Section 508 compliance designed in from day one.
• Contract work for Bublish, Trekkel, Golightly, and the Simon Wiesenthal Center: full-stack delivery, distributed teams, deployment ownership.
• AI model evaluation and task design for LLM training at Sepal AI (acquired by Mercor): designing and grading the technical tasks these models train on. One of two Occupational Reviewers in the web developer domain.
My stack: JavaScript, Vue.js, PHP, Laravel, Python, PostgreSQL, MySQL, AWS, Docker, Jenkins.
How I work: I reproduce the problem before touching code. I write tests. I read the surrounding codebase before adding to it. I do exactly what was asked, no silent scope creep, and I flag tradeoffs early. Done means deployed and verified in production.
Best fits: founders and small teams carrying a system they need the truth about, teams modernizing legacy code without breaking production, and anyone who wants a senior engineer to own architecture and ship. Start with one of the reviews below. We'll both know fast whether it's a fit.

Access + onboarding
You grant read-only code access; we cover what's hurting and what's been tried.
Audit
I review PHP versions and dependencies plus the JS/frontend, mapping risk and effort.
