About Me Hi, I’m Alex Lim, a multidisciplinary Python and Django engineer with more than 20 years of experience designing and building intelligent, automated, and full-stack systems for clients in telecom, AI, and enterprise software. My work blends engineering precision with creativity and problem-solving. I’ve developed platforms that automate workflows, manage complex data, and connect web, mobile, and IoT systems in ways that make operations faster and simpler. I started in electronics and communications engineering, moved into full-stack development, and later led research and development teams focused on innovation and AI-driven automation. I love building systems that connect ideas, people, and technology. What I Do I build reliable, scalable, and smart systems using: Backend development: Python, Django, Flask, FastAPI, GraphQL Frontend and mobile: Flutter, React, Vue, Bootstrap, Tailwind AI and automation: OpenAI API, LangChain, LocalAI, n8n, MCP Orchestration Data and integration: PostgreSQL, MySQL, MongoDB, Redis, Google Sheets, REST APIs Cloud and DevOps: AWS, Docker, Nginx, GitLab/Github CI/CD IoT and embedded systems: Arduino, Raspberry Pi, MQTT, robotics interfacing Each solution I create focuses on performance, maintainability, and long-term value. Highlighted Projects PAIR (Personal AI Remote): A cross-platform AI system that connects devices and users for seamless collaboration. NexPortal: A Django-based enterprise platform that automates telecom billing and uses AI for PDF invoice recognition. Catch-a-Gig: A job marketplace platform with credential uploads, matching algorithms, and ad dashboards. TeleBots: Telegram automation bots for provisioning, management, and telecom operations. NexSports and Traffic AI: Real-time analytics systems using Python, OpenCV, and TensorFlow for motion detection and streaming. SmartHome App: A Flutter IoT app that automates lighting and appliances with MQTT. Auto-Trader: A reinforcement learning trading bot using Python and scikit-learn. Pole Site Surveyor: A mobile and web app for geotagged telecom pole mapping and reporting. Each project was designed for reliability, documentation, and scalability. Skills and Technologies Languages: Python, Dart, JavaScript, C/C++, PHP Frameworks: Django, Flutter, Flask, FastAPI, Laravel, Node.js, React, Vue Databases: PostgreSQL, MySQL, SQLite, MongoDB, Firebase AI Tools: OpenAI API, Pandas, NumPy, SciPy, Roboflow, OCR, OpenCV Automation Tools: n8n, Zapier, Google Apps Script, ClickUp API Version Control: Git, GitLab, Bitbucket, GitHub Cloud and Containers: AWS, Docker, Nginx, VirtualBox Creative Tools: Figma, Photoshop, Illustrator, Premiere, OBS, Unreal Engine I work comfortably across the entire development stack, from backend logic to automation and design. Work Philosophy I believe great systems are built with structure, collaboration, and purpose. My workflow includes: Open and consistent communication Clean, maintainable, and well-documented code Focus on scalability, testing, and reliability Respect for deadlines and deliverables I care deeply about creating results that last and make a measurable difference. Professional Background Head of Innovations, Research, and Development at NexLogic Telecommunications Network Inc., leading AI, automation, and IoT solutions. Founder of Protodev Information Technology Solutions, developing production-ready apps and automation systems. IEEE Awardee and National Physics Olympics Champion, recognized for innovation in electronics and robotics. Guest speaker at Mapúa Institute of Technology, San Beda College Alabang, and UP Los Baños, teaching and inspiring students in software, AI, and microcontroller projects. Experienced mentor, educator, and team leader with a passion for innovation and creativity. Let’s Work Together I’m based in the Philippines and open to remote or hybrid collaboration. I bring hands-on technical experience, strong documentation habits, and a commitment to building systems that run smoothly and scale easily.
