10+ years building cross-platform apps for iOS, Android, Web & Linux. Co-founder of aisay.co — an AI-powered AAC platform helping non-verbal children communicate. Expert in Clean Architecture, BLoC/Cubits & LLM integrations.
I don't just call an API — I ship AI products end-to-end. From co-founding aisay.co (a real-time AI voice engine helping non-verbal children speak) to generating ~15,000 AAC symbols with AI and building a full TypeScript MCP server, my focus is taking LLMs from prototype to production, on mobile, web and on-device — with the architecture, latency and cost discipline a shipped product demands.
Production integrations with OpenAI, Gemini & Claude — token streaming, function/tool calling, structured output and graceful fallbacks. Built right into Flutter & Node.js apps with proper error, cost and rate-limit handling.
Context-aware assistants grounded in your own data — embeddings, vector search, chunking strategies and retrieval pipelines that cut hallucinations and keep answers accurate, current and on-brand.
Privacy-first, low-latency inference that runs without a network — TFLite models, on-device Whisper speech-to-text and quantized pipelines for mobile, desktop and Linux. Ideal where data can't leave the device.
Custom Model Context Protocol servers and agent tooling that let LLMs safely act on your systems — the exact stack behind aacstandard.com's TypeScript MCP integration and its AI symbol-generation API.
Real-time AI voice engines, speech-to-text and text-to-speech, plus AI image/symbol generation — the production tech proven in aisay.co, serving non-verbal users with natural, context-aware responses.
Co-founder experience taking AI from idea to App Store — prompt engineering & evaluation, latency & cost optimisation, Clean Architecture and the CI/CD to ship it. Including ObywatelBielik, Poland's first open-source LLM project.
Co-founder & lead developer of an AI-powered AAC platform helping non-verbal children communicate. Live on iOS & Android. Built Flutter & Node.js/Express cross-platform app with a real-time AI voice engine, context-aware responses, JWT auth and multimedia API. Sole developer managing full product lifecycle — architecture, TestFlight, App Store, CI/CD and scaling.
Open AAC symbol standard — an open-source initiative generating ~15,000 AAC symbols with AI. Includes a full TypeScript MCP server integration, symbol design specification comparing PCS and Blissymbolics systems, and a tiered pricing API built for speech therapists and special education institutions across Poland.
Open to senior Flutter roles, AI integration projects, and co-founder opportunities. Based in Wrocław, available remotely.
