Full-Stack AI Developer | React & Node.js Expert | Machine Learning & NLP
Hi, I'm Filbert Sembiring Meliala!
Informatics Scholar (GPA: 3.97/4.0) | International Award-Winning Developer
I am a Full-Stack Developer and AI Engineer with a specialized focus on bridging complex Artificial Intelligence models with highly scalable web architectures. Currently pursuing my Bachelor of Informatics with a concentration in AI, I do not just write code?I engineer metric-driven solutions. My technical journey spans from deep learning frameworks like TensorFlow and PyTorch to engineering modern, mobile-first single-page applications (SPAs) using React.js, TypeScript, and Tailwind CSS.
My Expertise:
Artificial Intelligence & ML: I specialize in Natural Language Processing (NLP) and Computer Vision. I have hands-on experience fine-tuning advanced transformer models like BioBERT (achieving an 81.55% F1-score) , developing CNN-based emotion detection systems , and integrating the Gemini API using RAG architecture for context-aware chat.
Full-Stack & Backend Architecture: I build secure, high-performance backends. I am highly proficient in Node.js, Express.js, and FastAPI , utilizing databases like MongoDB, PostgreSQL, and MySQL. I focus on scalable RESTful APIs, JWT-based authentication, and efficient data processing.
What I Offer:
AI-Powered Web Applications: Leveraging my dual expertise, I can build complete end-to-end platforms that incorporate intelligent features?from sentiment analysis dashboards to generative AI tools.
Performance-Optimized Systems: I prioritize system efficiency. In past projects, I successfully streamlined backend routing and asynchronous request handling to optimize API response times by 20%.
Why Choose Me?
Award-Winning Problem Solver: My ability to deliver under pressure is validated by securing 1st Place at the Golden Code Hackathon (2025) and 3rd Place at the International BeachHacks (2024).
Proven Leadership & Project Management: As Vice Chairperson of PUMA Informatics, I led a 59-member cross-functional team, managing logistics and stakeholder communication for events with over 500+ participants. I understand project timelines, resource allocation, and clear communication.
Data-Driven Execution: I track metrics, whether it is achieving 85% classification accuracy in image datasets or increasing user engagement by 30% through optimized workflows.
