You will get a senior-level architecture audit + fix plan for your SaaS
Project details
Will your architecture hold when traffic doubles? If you're not sure, better to know now than find out the hard way. The system runs fine today, but it's getting slower and harder to extend, and you want a senior engineer to go through it and tell you the truth.
I go through your architecture top to bottom: how the pieces fit, how data moves, whether the multi-tenancy holds, where it cracks under load, and the security risks an experienced eye catches. You get a written report with diagrams and a prioritized plan for what to fix first.
I've spent 25+ years as a full-stack engineer, 20+ designing and running SaaS architectures. The longest run: a decade on a multi-tenant platform, 116 colleges, 2,000 users, 300,000 submissions, where architecture decisions stop being theoretical.
The difference here is simple. I can write the report, and I can write the code. Most architecture audits end at the diagram. Mine can roll straight into implementation with the same person who already knows your system.
I keep my plate deliberately light, start to finish. Before you buy, message me, and I'll tell you exactly when I can start.

About TJ
SaaS Architecture Audits & Legacy Modernization | Python, PHP, Vue
San Diego, United States - 4:41 pm 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.
Steps for completing your project
After purchasing the project, send requirements so TJ can start the project.
Delivery time starts when TJ receives requirements from you.
TJ works on your project following the steps below.
Revisions may occur after the delivery date.
Access + onboarding
ou grant read-only code access and share any architecture docs; we cover the system and current pain.
Audit
I go through components, data flow, multi-tenancy, DB, API, scalability, and security flags.
