    Welcome to my profile! Here are some quick testimonials before I get into the details of who I am and what I do: Jun 28, 2024 - 5 Star Review "Slavisa is very generous with his consultations and draws from a deep well of Ai, automation and programmatic experiences to get projects done better and faster than most. If your business can really benefit from programmatic automation, you probably need his help sooner than later." Jun 7, 2024 - 5 Star Review "Slavi was excellent and helped us a ton. Took a bunch of time to educate me on fundamentals of LLMs. He explains things in a very simple way so that you can relate to the information. Showed us how we would go about building out our solutions with the tools we currently have. Would 100% recommend Slavi to anyone looking to get started or improve on their use of AI and LLMs." May 18, 2024 - 5 Star Review "Slavi listened to my project requirements and walked me through the most eye-opening AI tutorial I've ever had. Within a single consultation, he gave me the tools so I could tackle the project myself. Keep in mind I don't come from a computing background and can't code at all. Slavi is a true expert in the field of AI and his communication skills are perfect. I will rehire Slavi if I ever need further support and wouldn't hesitate to recommend any business in engaging him for their job requirements." Please refer to my completed jobs below and job success score for further insights about my work. Quick Overview: I fell in love with AI when GPT-3 went public in November 2022. I immediately recognized its potential, quit my job, and committed myself to mastering this technology. Since then, I've built AI systems for healthcare providers, law firms, car dealerships, and tech startups. I specialize in taking AI from concept to production - handling everything from fine-tuning models to building secure, scalable systems that work in the real world. What I Do: I build custom AI solutions that make businesses more efficient and profitable. My work spans from creating lightning-fast voice communication systems (we're talking 500ms response times) to developing precise fine-tuning methods for specific business needs. I've spent thousands of hours working directly with: Tools & Technologies I've Mastered: AI Models & Systems OpenAI's suite (GPT-4, fine-tuning platform, Whisper, DALL-E) Anthropic's Claude family (3 Haiku through 3.5 Sonnet) Google's Gemini and Speech APIs Perplexity AI platforms Media Generation Sora for high quality video generation Eleven Labs for voice synthesis, cloning, dubbing, and audio enhancement Runway for video creation or animation Midjourney for image generation Suno for audio production Technical Foundation Core: JavaScript, Python Cloud: AWS, Google Cloud, Azure Databases & APIs: Both SQL and NoSQL Essential services: Twilio, Sendgrid, and more Why Work With Me: I've built multiple large-scale AI applications from the ground up. I know the regulations, the limitations, and most importantly, how to get these systems to perform in production environments. After spending 10+ hours every day for years working with AI, I've developed methods to: Create highly accurate fine-tuned models Build reliable streaming systems Integrate multiple AI services seamlessly Maintain security and compliance in regulated industries Real Results I've Delivered: Built a voice communication system that responds in under 500ms while handling sentiment analysis and database storage in real-time Created custom fine-tuning systems that significantly improve model accuracy for specific business cases Developed secure AI implementations for healthcare, media, legal sectors, and much more. Looking to Build Something Serious? I bring deep technical knowledge and hands-on experience to every project. If you need someone who can handle the complete AI implementation process - from architecture to deployment - let's talk. I can walk you through similar projects I've built and discuss how we can solve your specific challenges.
