I'm a Top-rated developer on Upwork with 100% job success and over 15 years of experience building software that solves real problems. I specialize in **Generative AI applications, scalable SaaS platforms, and full-stack solutions** for startups and established businesses. My approach is straightforward: understand what you need, build it right, and make sure it works reliably in production. What I Do Best ------------------ I build intelligent applications that combine cutting-edge **Generative AI** with solid engineering. Whether you need a SaaS platform with predictive analytics, a custom **Prompt Engineering/RAG** system, or a full-stack web application with AI features, I can help you from concept through deployment. **Delivered 50+ AI projects with measurable impact like 3x user engagement.** AI & Machine Learning --------------------------- - **Generative AI & Model Fine-Tuning** (custom GPT/Claude via OpenAI/Anthropic APIs) for content, images, video generation - **Prompt Engineering & RAG** for reliable LLM outputs in chatbots and automation - **AI Data Annotation/Labeling** pipelines for high-accuracy model training - Custom model development using TensorFlow, PyTorch, scikit-learn for predictive analytics - **AI Video/Image Generation** (Sora/Stable Diffusion integrations) - **MLOps** pipelines (Kubernetes, AWS SageMaker) and production deployment - NLP for chatbots/sentiment; Computer vision for image recognition - Data analysis/visualization (Tableau, Streamlit) SaaS Development ----------------------- - Multi-tenancy architecture and scalable application design - Subscription billing with Stripe, PayPal integration - User authentication, RBAC, and security best practices - RESTful APIs and **WebSockets** for real-time AI features - **AI Integration** (OpenAI, Claude, Gemini APIs) Technical Stack ------------------- Backend: Python, Django, Django REST Framework, Node.js, PHP, Laravel, Celery, RabbitMQ Frontend: React, Next.js, TypeScript, Tailwind CSS, responsive PWAs Databases: PostgreSQL, MySQL, MongoDB, Redis DevOps: Docker, **AWS (SageMaker, Bedrock, EC2/S3/Lambda)**, CI/CD (GitHub Actions) **AI Tools: Hugging Face, LangChain, LlamaIndex** How I Work -------------- Clear communication from day one—I ask questions to align on goals and success metrics. Use JIRA/Slack for organized updates and **weekly demos**. Clean, documented code with realistic timelines. **Resolve 95% of scope issues upfront.** Industries I've Worked With --------------------------------- - Finance & FinTech: Trading platforms, fraud detection AI - E-commerce: Recommendation engines, inventory optimization - Healthcare: HIPAA-compliant telemedicine, predictive analytics - Education: Personalized learning platforms - **Data & Analytics: BI dashboards, GenAI insights** What You Can Expect -------------------------- Practical AI implementation that works in production—not just demos. From architecture to deployment and support. **Targeting high-demand Generative AI, Prompt Engineering, MLOps projects**—available now for your next build. Let's Talk ----------- If you're building **AI Data Annotation tools, Video Gen apps, custom LLMs, or SaaS with AI edge**, let's discuss. Open for project-based or long-term work.
