Most of the WordPress projects that land on my desk fall into one of two camps: someone wants a site built properly from the start, or someone's site is half-broken and the last developer disappeared. I'm comfortable in both. I've spent years building and fixing WordPress sites, and somewhere along the way I stopped seeing "I tried Elementor and now nothing lines up" as a problem and started seeing it as a Tuesday. Whether it's a custom theme coded from a Figma file, a plugin that needs to do something off the shelf can't, or a layout that looks fine on desktop and falls apart on mobile, I can get it sorted without the drama. Here's where I'm genuinely strong: - Elementor - clean, fast builds that don't bloat the page or break on the next update. I also untangle messy Elementor sites other people left behind. - Custom themes - hand-coded themes when a page builder won't cut it, or deep customization of existing ones (child themes done right, so updates don't wipe your work). - Bug fixes & rescue work - white screens, plugin conflicts, broken checkouts, slow load times, "it worked yesterday." I diagnose the actual cause instead of guessing. - Speed & responsiveness - better Core Web Vitals, layouts that hold up on real devices, not just the designer's screenshot. I also handle WooCommerce, content migrations, and third-party integrations (payments, forms, email) when a project needs them. What you can expect working with me: I ask the right questions up front so we're not guessing halfway through, I keep you posted with quick Loom videos instead of vague status updates, and I tell you honestly if something's a bad idea before you pay for it. I'd rather under-promise and ship clean, tested work than overpromise and disappear. If you've got a build, a fix, or a site that needs ongoing hands - send me the details. I'll come back with a straight answer on scope, timeline, and cost.

Hi, I’m Hamnah, a Website Developer and UI/UX Designer who builds websites that move, convert, and actually work. I don’t just install a theme, replace the text, and call it finished. Every website I build is shaped around the business, the audience, and the action you want visitors to take. That may be purchasing a product, booking a service, submitting an inquiry, or understanding your offer clearly. I build websites using Shopify, WordPress, Webflow, Wix Studio, and Squarespace. I also develop fully custom-coded websites when a template or website builder cannot support the required design, functionality, or performance. That includes custom development using HTML, CSS, JavaScript, React, Shopify Liquid, and WordPress technologies. I handle both the design and development, so you do not need one freelancer to design the website and another person to build it. I manage the complete process, keeping the design, functionality, responsiveness, and user experience consistent from start to launch. I have built ecommerce stores, service-business websites, SaaS landing pages, portfolios, lead-generation websites, custom web applications, and responsive user interfaces for startups, agencies, and growing brands. I’m based in Des Plaines, Illinois, hold a Software Engineering degree from the University of Illinois Chicago, and bring 7 years of hands-on experience across website design, UI/UX, and front-end development.

I work with small business owners and marketing teams who know AI should be doing more for them — but can't figure out where to start, what to build, or whether what they've tried is actually working. That's where I come in. My engagements start with structured discovery: understanding how the business operates, where time and money are leaking, and what the actual goal is before anyone touches a tool. From there I scope the work, draft the SOW, and either lead the build or coach the team through it — depending on what the business actually needs. Coaching & AI Adoption A significant part of my practice is working directly with business owners and their teams on AI adoption. Not generic tool tutorials — structured, personalized sessions built around your business, your workflow, and your specific gaps. Some clients come in knowing nothing. Some have tried a handful of tools and gotten nowhere. Either way, we start where you are and build from there. Sessions run as standalone engagements or as an ongoing retainer, and I've developed curriculum for both individual owners and small teams making the shift to AI-assisted operations. Consulting, Systems & Implementation On the consulting and systems side, I diagnose operational pain points and design purpose-built AI solutions — financial dashboards, CRM pipelines, workflow automation, knowledge bases — engineered for the client's specific constraints, typically at zero infrastructure cost. On the content and strategy side, I architect generative AI production systems that replace traditional agency overhead: full multi-platform content operations running on lean AI stacks, with the metrics to show it. Recent work: a complete operational suite for a professional motorsport racing team (financial command center with live budget tracking, AI document intelligence, and a full sponsor pipeline CRM — two zero-infrastructure web apps, single sprint); a fully AI-produced weekly podcast now at Episode 30, growing 20% month-over-month; and an internal AI workflow transformation that replaced an 8-person freelancer team and documented over $200K in annual overhead reduction. Certified: AI Prompt Engineering & Advanced Data Analytics — Vanderbilt University (via Coursera) If you're past the tool-dabbling stage and ready to build something that actually runs — or just need someone to sit down and make sense of all of it with you — let's talk.
