Gig Summary
About this gig
3 MONTHS OF FREE HOSTING! MESSAGE ME BEFORE ORDERING!
I build custom AI chatbots, AI agents and complete AI products for Telegram, WhatsApp, Discord, Slack or your website. 102 completed orders since 2020.
Any AI model, any API:
* Any model available via API: GPT, Claude, DeepSeek, Gemini, Grok and more.
* Any open-source model, set up on your own machine or on a rented GPU server. I can help you rent it, set it up and maintain it.
* Integrations with payment systems, CRMs, Google services, Notion and any other service that has an API.
Not just text:
* Voice assistants that talk to your clients.
* Image and video generation of any complexity, via API or open-source models, with custom LoRAs when needed.
I take on any project, from the simplest ones to the most complex and controversial.
I don't just build whatever is written in the brief. First I study your business and what you actually need, then together we work out the best way to build it. I work for the result, not just to close the order.

FAQ
I need a specific AI model or a niche API. Is that possible?
Yes. Fine-tuned open-source models, custom LoRAs, private or poorly documented APIs. Tell me what you need and I will find a way to connect it.
I already have a bot or code from another developer. Can you fix or extend it?
Yes. I review the existing code, fix what is broken and add new features or AI on top. If it is faster to rebuild, I will tell you honestly.
My niche is unusual or considered high-risk. Will you work with it?
Yes. I have built products for crypto, trading, paid communities, gaming and other niches most developers turn down. I don’t judge the idea, I make it work.
Can you build a full platform, not just a bot?
Yes. Complete products with user accounts, payments, admin panels and real logic behind them. When it needs serious math, I build it: Monte Carlo simulations, Bayesian models, Kalman filters, Glicko ratings, Gale-Shapley matching, multi-armed bandits, HNSW vector search. With AI or without it.
I only have an idea, no technical spec. Is that enough?
Yes. Message me with the idea. I will ask the right questions, propose how to build it and plan it step by step with you before any work starts.
Is my project kept confidential?
Yes. Your idea, code, data and API keys stay private. Keys are stored on your side, and I am happy to sign an NDA.

Ongoing collaborationWorking with Iosif was an absolute pleasure. As a beginner in blockchain technology, I had a lot of questions and my contract had several issues. However, Iosif not only fixed all the issues but also took the time to explain them to me in detail.
