    I’m driven by the belief that every line of code and every test case should deliver real value to users. As someone who equally loves building features and breaking them, I bridge the gap between development and quality assurance, collaborating closely with product owners, designers and fellow engineers to ship seamless, reliable applications. A Human-Centered Approach: 🔍 I listen first: understanding user needs and business goals so I can anticipate where things might go wrong before they reach production. 🗣️ I communicate clearly: turning complex technical issues into concise, actionable insights for stakeholders and teammates. 💡 I innovate continuously: keeping one foot in “what works today” and the other in “what could work better tomorrow.” What I Bring: 🛠️ Full-Stack Development: HTML5, CSS3 & Sass, Bootstrap, Tailwind CSS, JavaScript (ES6+), PHP, SQL, Laravel, RESTful APIs 🤖 Automated & Manual Testing: Selenium WebDriver, JUnit, TestNG; detailed test plans, exploratory scenarios and usability checks ⚙️ API & Performance Validation: Postman for functional testing; JMeter for load, stress and scalability assessments 🚀 DevOps Foundations: Git—integrating tests into CI/CD pipelines for faster, safer releases 🤝 Soft Skills & Practices: Agile collaboration, cross-functional teamwork, clear bug reporting, mentorship mindset I thrive in environments where quality is everyone’s responsibility. Whether I’m coding a new component, writing an end-to-end test script, or pairing with a teammate to squash a tricky bug, I aim to leave each project more stable, maintainable and user-friendly than I found it.

    👋 Hi, I'm Wilhelm - an AI automation expert and backend engineer with a Master’s in IT. I’ve worked with 7 and 8-figure businesses to increase efficiency and cut costs by implementing automation systems. ⚡ I used automation to save a Managing Director 20+ hours monthly with an AI email triage system ⚡ I am engineering enterprise systems at GEBIT Solutions, a $40M rev tech industry leader ⚡ I’ve spent the last 7 years building enterprise level software used by millions of people every day Long story short, I know my way around digital tools and have zero doubt that I can make or save you at least ten times more than what you pay me. ——— If you're not convinced and want to read a bit more: I’m deeply passionate about simplifying complex processes and building systems that free people from tedious manual work. Whether it’s a backend service that needs to run at scale or an outreach workflow that saves hours of admin time, I approach every build with precision, clean logic, and long-term maintainability in mind. At GEBIT Solutions, I work on microservice-based architectures used in enterprise retail — with a focus on transaction workflows and fiscal compliance. These services are built using Spring Boot, event-driven with Kafka and Solace, and run in containerized environments with Docker and Kubernetes. With wizimate, I’m building practical automation systems inspired by top agency offers and tested across real workflows. A few current builds include: - Lead capture & cold outreach automation: auto-enrich leads, generate AI-written emails, and trigger CRM workflows - Email infrastructure & warm-up systems: domain setup, inbox management, and sending logic built for deliverability - CRM automations: structured tagging, lead scoring, and automated pipeline flows using tools like Airtable, Notion, or Pipedrive - Internal ops automation: connecting tools and reducing friction with no-code systems (Zapier, Make, APIs) I also had the chance to speak at Bosch’s internal "Prozess Café", where I shared thoughts on how modern automation parallels the evolution of coffee — combining my tech expertise with my experience founding a coffee brand and building a functional business from the ground up. If you're looking for someone who understands both the tech stack and the system strategy, I’d love to help you turn chaotic workflows into clean, scalable solutions. Let’s make something efficient — and fun — together. 🚀

    As a highly adaptable and well-rounded software professional, I specialize in full-stack development, with a strong focus on combining robust technical backends with intuitive, user-centric front-end design. My core strengths lie in Java, Python, and modern web development technologies, which I use to build high-performance, responsive, and scalable applications. I have extensive experience working with Java, including frameworks such as Spring Boot for backend RESTful services and JavaFX for desktop applications. My Java expertise forms the backbone of my Vaadin full-stack development, where I design and implement seamless end-to-end web applications. I utilize Vaadin’s powerful UI components, data binding, and routing system to create clean, interactive interfaces backed by secure and efficient Java-based logic. From integrating Spring Data and JPA for database operations to customizing themes and handling user authentication, I develop complete, cross-device solutions. On the front end, I work confidently with HTML5, CSS3, and modern JavaScript practices, ensuring visually appealing and mobile-responsive web applications. My UI design approach prioritizes clean aesthetics, accessibility, and performance optimization. In the realm of data handling, I leverage Python for data automation, analysis, and entry workflows, using libraries such as: * Pandas & NumPy – for efficient data manipulation and analysis, * OpenPyXL & xlrd – for working with Excel files, * Requests & BeautifulSoup – for web scraping and API interaction This empowers me to automate repetitive tasks, transform data, and seamlessly integrate backend logic with front-end presentation layers. 

 Beyond my technical development work, I also offer professional content creation and language services. I write clear, engaging, and informative content in English, Turkish, and German, and provide translation, audio transcription, and subtitle generation. What sets me apart is my ability to turn complex challenges into practical, intuitive solutions, and to do so with an attention to both functionality and user experience. Whether working independently or as part of a team, I take pride in delivering full-spectrum solutions that are efficient, elegant, and tailored to the user’s needs.
