Lucas C.

Senior AI Developer, Computer Vision, LLM, and Deep Learning Expert

Hi, I’m Lucas. I’m new here on Upwork, but I’ve been working in AI, Generative AI, and Machine Learning for a little over 5 years. I have done Masters in Computer Science, and have worked with more than 15+ AI projects, and most of my work has been helping startups and companies build practical AI solutions—things like chatbots, generative models, computer vision systems, and data-driven tools. ✔️ Core Expertise - Machine Learning & Deep Learning - LLMs & Chatbots (GPT-4o, GPT-4.5, Claude, Mistral, Gemini, Llama 3.1, LangChain, RAG, RL, AI Agents) - Computer Vision (object detection, segmentation, OCR, face recognition, pose estimation, tracking, AR/3D reconstruction) - Generative AI (Stable Diffusion, DALL-E, MidJourney, Runway Gen-2, Muse, SORA, GANs) - Speech AI (STT, TTS, voice cloning – Whisper, Deepgram, ElevenLabs) - Data Science (time series forecasting, data mining, text mining, classification) ✔️ Full-stack & GUI Development - Database Design & Optimization (SQL & NoSQL – MySQL, PostgreSQL, MongoDB) - Cloud & Deployment Expertise - AWS (EC2, S3, Lambda, SageMaker) - Azure (ML, Functions, Blob Storage) - Google Cloud (AI Platform, Cloud Storage) - DigitalOcean ✔️ Frameworks & Tools - Deep Learning: PyTorch, TensorFlow, Keras - Computer Vision: OpenCV, YOLO (v5–v11), SAM, Mask-RCNN, DeepLab, U-Net - Generative Models: StyleGAN, CycleGAN, SRGAN, 3DGAN - NLP & Multimodal: GPT-4, GPT-4o, SORA - Programming Languages: Python (primary), C, C++, MATLAB - Data Tools: NumPy, Pandas, Scikit-learn, SciPy - Web & App Dev: Flask, PyQt, Tkinter I enjoy the mix of problem-solving and building—figuring out how to take an idea and turn it into something that actually works and creates value for the business.
