With 4+ years of experience and 100+ successful projects, I help startups, enterprises, and researchers turn ideas into production-ready AI products that create measurable business impact. I specialize in building end-to-end AI solutions across Generative AI, multimodal LLMs, LangChain, RAG pipelines, Computer Vision, NLP, Speech AI, AI automation, and scalable SaaS development. From fine-tuning custom models to designing robust backend systems and deploying cloud-based applications, I deliver solutions that are practical, reliable, and built for real-world use. I develop: * RAG systems and enterprise search platforms * Custom AI chatbots and LLM-powered assistants * AI automation workflows and business process integrations * Document AI and OCR pipelines * Computer Vision and medical imaging applications * Speech-to-text, text-to-speech, and voice-enabled assistants * Generative image and video AI solutions * AI SaaS platforms, internal business tools, dashboards, marketplaces, MVPs, and API-driven products My work covers the full product lifecycle: AI strategy, architecture, model selection, prompt engineering, LoRA and fine-tuning, backend logic, API development, database optimization, automation, deployment, and long-term scalability. Alongside AI-first development, I also build complete software products using FastAPI, Flask, Node.js, Next.js, Supabase, Bubble io, Lovable AI, React, and modern cloud platforms such as AWS, GCP, and Azure. ⚙️ Tech Stack & Skills Programming: Python AI Frameworks: PyTorch, TensorFlow, Keras, LangChain LLMs & RAG: OpenAI GPT-4/GPT-5, LLaMA, Gemini, Claude, Mistral, semantic search with embeddings, keyword search with BM25, hybrid retrieval, RAG pipelines Generative AI: Stable Diffusion, DALL·E, LoRA, AUTOMATIC1111, DreamBooth, ComfyUI, Hugging Face models, GANs, CycleGAN, VAEs Computer Vision: Transformers, OpenCV, MediaPipe, OCR, CNNs, Autoencoders, YOLO 3D Data: Open3D, PyTorch3D, 3D U-Net, depth estimation, point cloud processing Machine Learning: Scikit-learn, XGBoost, classification, regression, clustering, traditional ML models NLP: spaCy, NLTK, Word2Vec, TF-IDF, LSTM, RNN, GRU Speech AI: Whisper, Coqui TTS, Google Cloud Speech, Azure Cognitive Services, Amazon Polly Databases & Vector Stores: PostgreSQL, MySQL, MongoDB, Pinecone, ChromaDB, FAISS, Supabase Backend Engineering & MLOps: FastAPI microservices, Flask APIs, OpenAPI specification and code generation, CI/CD with GitLab, Python packaging with UV and Poetry, ML data pipelines, MLOps best practices Deployment: Docker, AWS, GCP, Azure, MLflow, Runpod Frontend & Product Development: Streamlit, HTML/CSS, Webflow, Lovable AI, Bubble io, React Backend & Full-Stack: Flask, FastAPI, Node.js, Next.js, Supabase Mobile Apps: Flutter Automation & Workflows: n8n, Zapier, Make, Claude Code, OpenClaw, custom pipeline orchestration 🌟 Why Clients Hire Me ✅ 130+ successful projects and a 100% Upwork Job Success Score ✅ Strong expertise across AI, software engineering, automation, and cloud deployment ✅ Clean code, optimized models, rigorous testing, and on-time delivery ✅ Scalable, production-ready systems built for real business needs ✅ Strategic product thinking, not just technical implementation ✅ Clear communication, transparent workflows, and consistent progress updates I care deeply about communication, clean architecture, and long-term stability, not just making something “work.” I focus on building solutions that are maintainable, scalable, and aligned with business goals. Many of my clients return for additional projects because I stay involved, suggest better approaches when needed, and keep the development process simple, collaborative, and transparent. Whether you need an AI chatbot, RAG application, fine-tuned LLM, OCR pipeline, computer vision system, voice AI product, generative media workflow, no-code MVP, or a fully custom SaaS platform, I can help turn your idea into a robust, production-ready solution. Let’s connect and discuss how we can build an AI-driven product that delivers real value.
