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, composer, and npm dependencies frozen since the last team touched them. That's usually when teams call me. 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 the risk and effort spelled out per step so you can plan around your release schedule.
I've been a full-stack engineer for 25+ years, 20+ of it dragging long-lived PHP and JavaScript forward without breaking the people who depend on it. The biggest: a decade on a multi-tenant platform serving 116 colleges and 2,000 users.
And 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 TJ
SaaS Architecture Audits & Legacy Modernization | Python, PHP, Vue
San Diego, United States - 4:16 am local time
Most of my work starts the same way: a fixed-scope audit. I look at 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.
For 25+ years, I've built and modernized mission-critical 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:
- 10 years owning a multi-tenant SaaS platform for the California Community Colleges system. 116 colleges, 2,000+ users, 300,000+ submissions. Full lifecycle from architecture through production.
- AWS data warehouse and ETL (Glue, S3, Redshift) feeding analytics in JasperReports and Apache Superset.
- Auth and access control built right: RBAC, SSO, Keycloak.
- 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). Promoted to Occupational Reviewer for the web developer domain.
My stack: Python, PHP, JavaScript/TypeScript, Vue.js, Laravel, 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.
Best fits: SaaS owners carrying technical debt that needs a steady hand, teams modernizing legacy systems without breaking production, and founders who need a senior engineer to own architecture and ship. If that's you, start with one of the audits below. We'll both know fast whether it's a fit.
