Complex WordPress & WooCommerce sites
Custom themes, ACF-driven content, WooCommerce templates, product logic, store/location behavior, and maintainable editor-friendly systems.
Jason Martinez Senior Front-End Developer & WordPress Architect
I help teams take control of complex WordPress, WooCommerce, and marketing websites by improving performance, accessibility, maintainability, tracking, and long-term reliability.
With 17+ years of agency experience, I'm comfortable stepping into inherited codebases, unclear documentation, technical debt, urgent fixes, and cross-functional web work that needs steady senior judgment.
I'm currently open to senior front-end, WordPress architecture, web platform, and technical lead roles.
Best-fit Scenarios
Where I help most
I'm a strong fit for teams that need a senior developer who can step into real-world web systems, make sense of the moving parts, and keep progress steady even when the codebase, documentation, or workflow is less than perfect.
Marketing-connected websites
Sites that need clean structure, performance, tracking support, forms, SEO awareness, redirects, analytics, and collaboration with marketing teams.
Inherited & under-documented codebases
Existing websites with technical debt, plugin risk, inconsistent patterns, urgent fixes, unclear ownership, and long-term reliability needs.
Teams bringing web ownership in-house
Companies that want more control, faster turnaround, better documentation, safer workflows, reduced outside dependency, and clearer technical standards.

Technical Ownership
Helping teams take better control of their web stack
After years inside agency web development, I understand what companies need when they want more ownership of their web stack: faster turnaround, more direct communication, better technical access, cleaner systems, stronger documentation, safer workflows, and a practical partner who can make the transition manageable.
Faster turnaround
Help internal teams move quicker on website updates, bug fixes, landing pages, tracking changes, forms, and marketing requests without turning every small task into a larger project.
Direct communication & technical access
Work closely with marketing, design, leadership, and outside partners so questions get answered faster, requirements are clearer, and technical decisions do not get lost in translation.
Cleaner systems & safer workflows
Review themes, plugins, hosting, integrations, deployment habits, and recurring pain points to reduce fragility and make future changes easier to plan, test, and release.
Documentation & long-term ownership
Create clearer documentation around site structure, custom functionality, plugins, reusable components, access, deployment steps, and maintenance needs so the team is less dependent on tribal knowledge.

About
Built through real agency web work
A career shaped by real client work, long-term maintenance, and practical technical decisions.
I've spent 17+ years in agency web development building, maintaining, improving, and troubleshooting websites for real clients with real constraints.
That experience shaped how I work: practical decisions, clean handoffs, maintainable systems, steady communication, and a strong bias toward solving the actual problem instead of only shipping the visible request.
Over time, I became a long-term technical anchor across custom WordPress builds, WooCommerce systems, accessibility remediation, performance work, maintenance, and client support. For a stretch, I was the only developer on the team, which taught me how to balance new work, urgent fixes, documentation, technical decisions, and long-term site reliability.
I'm at my best in environments where websites are important to the business, the work needs a mix of planning and hands-on development, and the team needs someone who can build thoughtfully from the start or make steady progress within an existing site or web stack.
Testimonials
What managers and teammates say
Excerpts from LinkedIn recommendations from people who worked with me directly across development, client support, project delivery, and long-term website maintenance.
I've had the pleasure of working alongside Jason Martinez as his manager at Enilon for the past 9 years, and I can say without hesitation that he's one of the strongest frontend developers I've had on my team.
Jason brings a rare combination of technical depth and genuine care for the work. His code is clean, thoughtful, and built with the long game in mind — but what sets him apart is how he shows up beyond the code. He's the kind of developer who asks the right questions before diving in, anticipates problems before they surface, and takes real ownership of outcomes, not just tasks.
What's impressed me most is how naturally he communicates — whether he's walking a client through a technical concept or collaborating with our internal team across SEO, paid media, and dev. He has a way of making complex things feel approachable without losing any of the nuance, which is a genuinely rare skill in this industry.
Jason is self-motivated, dependable, and always brings a solution-oriented mindset to whatever lands on his plate. Any team would be lucky to have him — I know ours is better for it.
I have absolutely loved working with Jason on projects for many years, and look forward to many more. He's dependable, detail-oriented, and comes up with solutions, rather than just simply code. I never have to worry about clients or projects when Jason is involved, and that's such a burden lifted. 100% recommend Jason for your development projects!
I can't say enough about Jason. He's a great front-end developer, team player, problem solver… and he's funny too :) Highly recommend Jason for any team looking for someone they can trust, that will jump into anything, deliver great work and be a fun team member.
