What I do
What I build every day. Click a topic to see the details.
I build AI assistants, chatbots and agents based on large language models (LLMs). They can search your documents, answer questions and do real tasks. Tech: RAG, vector databases, prompt engineering.
I install and run open-source AI models on your own servers, so your data stays inside the company. Private chatbots and assistants, lower costs and full control.
I automate boring, repeating work: emails, documents, reports, data entry and lead handling. Scripts and AI do the routine, your team makes the decisions.
If it has an API, I can connect it. I link CRMs, online shops, payments, mailing tools and AI services, so data moves between them automatically. REST, GraphQL, webhooks.
I set up, customize and build CRM systems: sales pipelines, contacts and leads, data import, automatic follow-ups and clear dashboards for the team. Also with AI features inside.
Websites, web apps and online shops, from the database to the user interface. Python (Django, Flask), PHP, JavaScript, WordPress, WooCommerce, MySQL, PostgreSQL.
Apps for iOS and Android built with Flutter and Swift, connected to your systems and APIs.
Fast well-built websites that rank in Google and appear in answers from AI assistants (GEO, AEO). Page speed, structured data, technical SEO audits.
I worked in cybersecurity, so security is part of every project: safe logins and user access, data protection, security audits and penetration tests. I also protect AI tools against misuse.
Servers and cloud set up the right way: AWS, Azure, Google Cloud, Render, Netlify, Linux and Docker with automatic deployments and backups. Also for running your own AI models.
