Lenglee🚀 Backend Developer & DevOps Engineer 🌐
Greetings! I’m Lenglee, a backend developer & DevOps Engineer with 4 years of experience building systems in a variety of languages and frameworks — from the first proposal through to production.
🧩 I design and build APIs of every shape, and manage the complex databases behind them so the data layer stays predictable as a product grows.
🤖 I integrate backend systems with AI models, backed by a working knowledge of machine learning and image processing.
⚙️ On the DevOps side I take systems all the way to production and keep them observable, using monitoring tools to track performance rather than guess at it.
📱 I also understand frontend development for both web and mobile — enough to build the whole path when a project needs it.
🛠️ The tools I reach for day to day:
📬 Feel free to reach out about backend architecture, cloud infrastructure, AI integration or anything that needs to run reliably in production.
