I have formidable Linux (RHCA, RHCSE) and Java (SCJP) experience, but I am more interested in Python and Android recently and I gathered some knowledge in many distinct areas (Novell, Oracle, MySQL, PHP, Cisco, etc.). I'm a general IT specialist - non-trivial / multidisciplinar problems gravitate to me, as I like to tinker and dissect problems. Having a bit of OCD (even though I prefer the term "perfectionist") I also enjoy menial tasks like cleaning up databases, commenting code or creating user training manuals. I am looking for side jobs, projects.

Are you looking for a Hungarian content writer, translator, or voice-over artist? Then I am your ideal choice. I can write engaging content (with SEO optimization if needed) for websites, blogs, portfolios, and almost anything. I am passionate about literature. My favorite hobby is reading and writing books and novels in both Hungarian and English language. When I was in my twenties, I lived from selling and writing books. Later I worked as a software developer (Python, C++, Jave), but reading and writing remained my favorite activity, that is the reason I am working as a Hungarian writer, translator, and voice-over artist nowadays.

Hello! 👋 I'm a seasoned entrepreneur with extensive experience in business management, web technology, automation, and data analysis. I founded and scaled two startups—one successfully ($500K in monthly sales, 10 collaborators before selling) and one I shut down last summer, which led me to UpWork, where I now bring my expertise to new projects. I'm straightforward and efficient. Many who have worked with me say I’m one of the fastest and most precise people they’ve collaborated with. I love learning, thrive on tackling challenging projects, and take full initiative and ownership in everything I do. With the rise of AI, I’ve shifted my focus to the tech side of web work. Working alongside LLMs is a game-changer—you can build, iterate, and ship faster than ever, punching far above your weight. AI isn’t just a tool; it’s a shift as profound as the rise of the internet. Intelligence is no longer scarce, opening endless opportunities to optimize, automate, and rethink how we work. Together, let’s build something that keeps you ahead of the curve. My Favorite Things to Work On: 🔹 Tech & Development: - Python App Development (Docker, FastAPI, GCP, AWS) - AI Agents & LLM Workflow Automation - Airtable App Development - Document Processing & OCR (AWS Textract, Tesseract) - Graph Databases (Neo4j, Cypher, NetworkX) - Task Automation (Zapier, Make.com, N8N) - FNMA & MISMO Data Processing (Mortgage Automation) - Data Pipeline Design & ETL Workflows - API Design & System Integration 🔹 Business & Strategy: - Troubleshooting Organizational Issues - Optimizing Productivity & Workflow Systems (Notion, Asana, Airtable) - Building Businesses from Scratch - Strategic Planning & Technical Project Management 🚀 I only work with people who make decisions and move fast. I expect quick feedback, rapid iterations, and a bias toward action. If a project drags due to indecision or slow responses, I'll call it out—and if nothing changes, I’ll move on.

Are you struggling to utilize AI solutions like ChatGPT, DALL-E, or Large Language Models for your business? You know that AI adaptation is key, but not sure how to get the most out of it? I help my clients to take advantage of the best Data Science tools in their projects to grow. I help early-stage startups adopt AI solutions without spending hundreds of thousands of dollars on complex systems. Here are some of the results my clients are getting: 🏅 “I strongly recommend Bence to anyone looking for "applied" expertise in OpenAI.” Designed 8 potential Machine Learning systems for their business. 🏅” Amazing job - we’ve never monetized our marketing data until now” – Analyzed survey data to get insights from their users' behaviors to make their marketing plan data-driven I’ve helped my clients by building Python scripts and RESTful API back-end systems that improve their workflows by using the latest AI solutions. We may be a great fit if you are thinking of: 🔑 “Want to utilize AI solutions but not sure if it is feasible” 🔑 “I'm NOT a Machine Learning expert, and I don't have time to mess around with the latest industry trends!” 🔑” need someone to take this AI project, and get it done at a high level, following the latest software developer principles like clean code" I have 4 years of professional experience as a full-time Python developer when I have designed, developed, and delivered 17 high-quality, production-ready, end-to-end Python and Machine Learning projects at BlackRock and Morgan Stanley. I'm also confident particularly comfortable working with clients in finance including the stock market, marketing agencies, and SaaS (B2B, B2C). Here is my tech stack: ✅ Python ✅ OpenAI (leverage the latest Large Language Models - LLM models) ✅ Keras (building unique Deep Learning solutions) ✅ Sklearn (utilizing Machine Learning algorithms) ✅ SQL (query database) ✅ Pandas / Numpy (for data analysis) ✅ Django / Flask (building RESTful API back-end) ✅ GitHub Actions (building CI/CD pipelines to deploy production code) ✅ Jupyter Notebook (for data visualization and data exploratory) ✅ Flutter/Dart (for mobile app development) SOUND LIKE A FIT?
