- Deployed battle tested Next.JS Apps for multi-million dollar revenue CNC machine shops - Created automations that have saved countless headaches and hours I build bespoke custom software that saves businesses in SaaS fees | Next.JS, PHP, Java I'm an A-Z solutions architect who understands business logistics; my background involves designing, creating, deploying, managing full-stack ERP's including securing enterprise networks. Creating automations and bespoke apps for complex workflows. Most developers can write code. I can build systems that run your business, I bridge the gap between "IT" and "Software Engineering," creating automations that are secure and solve real business needs and not just side projects built for no purpose. My Common Sense Approach - Logical Thinking I have common sense; I clue into your business needs and work with it, I ask questions where questions are needed; I like immersing myself from the clients perspective and seeing how they see things and creating a world that works around you and your needs. Get rid of the nonsense apps that have too many dials that you can't even dream of using, clogging up your mind from doing what's important: your work. My Expertise - I don't just build garbage and hand it off to the next person, I want to build something that is truly what people need and want - I bridge gaps where you didn't even know you could've bridged it to begin with - My portfolio speaks for itself, If you've made it this far into reading my portfolio, big smile from me, it shows that you care just as much as I do. I want to thank you for that, you're someone that understands that just hiring someone doesn't just mean getting the 'best' and the 'fastest' talent, but talent that grows with you. Do you want to build a mobile app? - I have experience in founding mobile apps, although I have not gotten to the finish line with mobile apps, I do have experience in - Expo GO - React Native - Supabase + Clerk Auth + Expo GO My Philosophy: "No More Monthly Fees" I hate monthly fees, you hate monthly fees; let's create a world where people don't own you, you own yourself, you shouldn't be beholden to amazon on a whim deciding to increase their fees 400% and you have no say in it. - I build software you own for life - I create tools that fit to your owkrflow - Cut the clutter, no useless dials you'll ever touch, just what you need. I build Enterprise grade infrastructure tech; - Via: Docker, TrueNAS, Ubiquiti, Wireguard/OpenVPN, Linux What I code in; - Next.js, React, Node.js, MariaDB, PostgreSQL, PHP, Vanilla JS, TS - React Native
