What I deliver as an AI engineer

✓LLM integration: OpenAI, Claude, custom prompts and guardrails in your stack
✓AI chatbots and virtual assistants (web, Telegram, WhatsApp)
✓RAG pipelines over your docs - private knowledge bases, not public ChatGPT
✓AI for e-commerce: semantic search, recommendations, support deflection
✓Workflow automation: document parsing, email triage, report generation
✓ML model hooks for analytics and forecasting where ROI is measurable
✓API design, monitoring and fallbacks when models throttle or fail

How I work as a senior AI developer

I start with a measurable outcome - “deflect 80% of support tickets” - not “add AI” to the homepage.

Architecture first: where data lives, how prompts version, what happens when the API is down.

I prototype in days on a small dataset before full integration into Laravel, React or WordPress.

GDPR-minded: EU hosting options, keys in env vars, no training on your data without consent.

Polish and US deployments get locale-aware prompts and human escalation when confidence is low.

About me

I'm Viktar Liukevich

Full-stack developer · 15+ years creating web

I am Viktar Liukevich, a senior AI developer and AI engineer in Warsaw with 15+ years in web - I integrate LLMs into real products that survive API limits, bad prompts and messy user input.

Clients hire me as an AI engineer when they need someone who codes the integration: RAG over their docs, support bots wired to CRM, catalog search that understands natural language - not a strategy deck or a no-code widget that breaks in week two.

For computer vision, large-scale model training or dedicated MLOps, I bring in AI/ML partners in Poland, Europe and the USA under NDA. You work with me as lead AI engineer; I own architecture and review every endpoint before production.
