I help businesses build, improve, and maintain software and infrastructure they can rely on. Clients usually come to me when they need someone who can take ownership—not just complete isolated technical tasks. I help launch new platforms, modernize existing systems, improve reliability and performance, automate operations, and solve problems that are slowing the business down. My focus is always the outcome: stable systems, smoother operations, less downtime, easier maintenance, and a setup that can grow with the business. I'm based in Germany and communicate fluently in English (C2), German (C1), and Romanian (native). I also operate my own hosting infrastructure, which can be useful for development, staging, testing, and deployment when a project needs it. You can expect clear communication, realistic commitments, and dependable follow-through. I'm also available after delivery for ongoing development, maintenance, monitoring, improvements, and long-term technical support. If you need someone experienced who can take responsibility for the technical side and stay involved long-term, I'd be glad to help. menos -

I'm Beatrice. Houston is where my desk is. The internet is where my clients are. I'm picky about projects because bad fits waste everyone's time, including yours.

The internet is where my clients are. I'm picky about projects because bad fits waste everyone's time, including yours. Currently have room for 2, maybe 3 if the work is interesting enough to skip weekends. I once had a client cry over a business card. Another yelled at me because his website loaded in 4 seconds instead of 2. I count both as wins. That tells you everything. I care about how things feel in your hand and how they work under the hood. Most people pick one. I picked both because I couldn't stand watching good design die in bad development, or great code wrapped in ugliness. Started in 2012 with ink and paper. Packaging that sold products before anyone read the label. Logos that worked on billboards and favicons. Print taught me restraint: if it doesn't work at 1 inch, it doesn't work. Then screens ate the world. Clients started asking for "the same feeling, but online." I learned to build what I designed, not because I wanted to code, but because I couldn't trust anyone else to protect the details. Now I do both. One brain, no broken telephone between design and development. 🟍 The work: ▶ Visual identity → logos, packaging, print systems that actually get printed (I know paper weights, color profiles, which printers won't ghost you) ▶ Digital presence → websites that load fast, rank higher, convert visitors. WordPress, Shopify, Squarespace, Webflow, Wix (I know which one fits your actual life, not my preference) 🟍 Recent scars & wins: 🙮 Rebranded a Houston coffee roaster → new bags on shelves, Shopify store for wholesale, owner stopped answering 2am reorder emails... 🙮 Law firm that looked like every other law firm → custom typography, real team photography, green instead of navy, WordPress site that loads before you blink... 🙮 Yoga instructor who wanted "just a logo" → full identity with texture and breathing room, Squarespace site that felt like her classes: grounded but floating What I actually do: Translate what your business is into what people see, then make it work everywhere. Print, screen, phone, packaging. No "strategy decks." No handing you off to a developer who ruins the spacing. I design it, I build it, I answer when it breaks. Send me your mess; visual, digital, or both. I'll tell you what's salvageable and what needs to burn. menos -
