Top Rated
Project details
You will get a fine-tuned Large Language Model (LLM) built specifically for your domain, legal, health, finance, education, or any niche with proprietary knowledge, using GPT, LLaMA, or custom Hugging Face models.
With hands-on experience in end-to-end LLM fine-tuning, prompt optimization, tokenizer alignment, and deployment on scalable infrastructures, I specialize in transforming general models into expert-level assistants tailored to your business workflows.
Whether it's making your documents searchable, automating domain-specific Q&A, or training a compliance-aware chatbot, I’ll deliver a model aligned with your needs and compliant with modern inference standards.
All work is conducted with attention to reproducibility, ethical handling of your data, and performance benchmarking. Let’s take your AI from generic to expert-level with a private model that knows your domain like an insider.

Senior AI Systems Engineer, n8n & LangGraph Architect for Autonomous Lead Intelligence
Umer and the team did an excellent job on this project. They helped us build a much more reliable lead research workflow using n8n and LangGraph. The new system improved data accuracy, reduced manual verification, and lowered our API costs. Communication was clear throughout, and they were responsive to feedback and changing requirements. Very knowledgeable and easy to work with. We look forward to working with them again!

Need an n8n automation + GPT engineer to audit our workflows
Working with Umer and his team on our n8n workflow audit was a great experience. They quickly understood our production automations across CRMs, databases, Python services, and OpenAI integrations, and delivered a focused, insightful review. Their ability to identify reliability gaps, webhook and retry issues, and LLM optimization opportunities was especially valuable.
Communication was smooth and professional throughout. Umer and the team provided clear, practical recommendations to improve visibility, cost efficiency, and overall maintainability. We would gladly work with them again.

AI DEVELOPER FOR QUICK FIX/ONGOING TASK
Before working with Zeki Expert Solutions, I spoke with several other companies about integrating AI into my company's website. Many of them focused on selling generic tools or promised quick results without understanding how a real media platform operates. Some pushed prebuilt packages that didn’t fit my site’s design, while others couldn’t explain how their AI would actually improve workflow or content quality.
When I met Umer, Salman, and their web development team at Zeki, the difference was clear. They took time to understand my brand and how we cover everything across tech and entertainment. They asked the right questions, explained each step clearly, and built solutions tailored to how Fluorescent Media runs.
Their approach was transparent, collaborative, and focused on long-term success instead of shortcuts. The AI tools they developed now help my writers and editors work more efficiently, automate repetitive tasks, and improve article recommendations and SEO insights.
I chose Zeki because they cared about the end result as much as I did. The partnership has completely transformed how we manage and produce content. If you want a team that truly understands AI integration and delivers real, lasting value, Zeki Expert Solutions is the one to trust. 100% recommend them to anyone looking for a company who is on top of communication and easy to work with!
