Hire the Best DotNetNuke Developers
in the United States

I build the systems businesses actually run on — automation pipelines, AI-powered workflows, and the custom web infrastructure to tie it all together. Through Onizuka Studio, I work with a small senior team delivering end-to-end automation across Zoho One (CRM, Books, Flow, Creator, Sign, WorkDrive), Make, Power Automate, and custom API integrations — including OpenAI and Claude AI. Recent work includes: - HR onboarding systems that auto-populate state and federal forms, capture e-signatures and ID verification, and route everything to the right place automatically - Field safety systems with daily QR check-ins and OSHA-compliant incident reporting - Full sales pipelines from inquiry to invoice, PO, and BOL — zero manual entry - AI-powered web apps with live deployments On the development side, I've been a DNN/ASP.NET front-end developer since 2004. That means I know legacy systems and how to modernize them without burning everything down. I don't just build automations — I build systems that scale. We've been on Upwork since 2014 with 50K+ in earnings and exclusively 5-star reviews. We run lean, take on select projects, and do the work right. If you're ready to stop duct-taping your business together, let's talk.

𝗢𝗡𝗘 𝗟𝗜𝗡𝗘𝗥 I'm passionate about serving my clients ethically to give them the best solution to their technical problems without wasting their money. 𝗦𝗨𝗠𝗠𝗔𝗥𝗬 I've been involved with the web and digital marketing space for over 20 years and involved with information technology for over 30. In 2005, I started my own web development and marketing company and have worked with all types of businesses from solopreneurs and non-profits up to Fortune 500 corporations. Before that, I was at Chevron for 21 years. I was responsible for internal and external web systems, ensuring they were up 24x7, systems had been fully QA tested before going to production, and all maintenance was taken care of. 𝗧𝗛𝗘 𝗚𝗢𝗥𝗬 𝗗𝗘𝗧𝗔𝗜𝗟𝗦 At the heart of it all, I'm a technologist. Or a nerd. You pick. I love technology and making it work for my clients. However, I won't communicate with you in geek-speak (although I can if you want me to). I excel at taking the technobabble and turning it into business-speak that my clients can grasp and understand. Then I implement it on their behalf and take care of it behind the scenes, so they don't have to! WordPress security is my passion because hackers love breaking into WordPress websites. Over 90% of all website hacks are on WordPress. I specialize in UNhacking websites that have malware or defaced pages and hardening sites so they can't be compromised again. Hardening a site is far more than just throwing a plugin at it. When working on new websites (or a refacing) I take boring we-focused websites and transform them into attractive client-focused portals that visitors understand and engage with. If your clients and customers don't understand what you do in about 1 second, they're hitting the "back" button and going somewhere else. I'm a big fan of Donald Miller's "StoryBrand" technique and I implement that on my clients' websites to engage their audience.

𝗣𝗘𝗥𝗦𝗢𝗡𝗔𝗟 𝗠𝗜𝗦𝗦𝗜𝗢𝗡 Giving back is hugely important to me, and I've been a volunteer for most of my life. I worked two summers in rural Latin America (Guatemala and Paraguay) as a teenager giving free health care to the people. I've helped build multiple houses for Habitat for Humanity. I've given 15 gallons of blood and started the San Francisco Bay Area's largest community blood drive in 2002. It's now in the top 10% of the nation and so far, has collected over 10,000 units of blood.
