Founder — Writer, Developer & Editor
Todd L. is the founder of TL3 Communications and the person behind TL3 Tools. He is a strategic technical architect with more than 25 years of web development experience — including 20 years specialized in the WordPress ecosystem — grounded in ISP-level infrastructure: DNS, Linux, and Apache, alongside deep mastery of PHP and modern JavaScript.
Since 1996 he has led full-stack engineering at TL3 Communications, administering DNS, mail, and Linux-based hosting for a diverse client portfolio and turning complex business requirements into high-performance digital products. He has architected enterprise-grade WordPress Multisite environments with proprietary page builders and automated AWS S3/CloudFront media pipelines, built custom sites for churches and small businesses, shipped high-traffic entertainment and film promotion sites including a WordPress-based charity platform for Disney’s Star Wars, and engineered custom themes and CMS extensions at senior level for clients throughout his career.
That background drives how TL3 Tools works: every calculator runs client-side in your browser, with each formula checked against published references and hand-computed examples before it ships.
