    How we could work together

    • Build AI pipelinesLLM routing, RAG workflows, multi-model failover, context budgets and agents with tool use.
    • Add AI to an existing productOpenAI, Claude, Gemini and embedding-based retrieval wired into what you already run.
    • Real-time AI systemsVoice pipelines, streaming completions and WebSocket conversational interfaces.
    • Design scalable APIsREST, GraphQL, WebSockets and webhooks in Python or Node.js.
    • Stabilize productionSlow APIs, database contention, race conditions, stuck Celery workers and failing async pipelines.
    • Modernize frontendsAnt Design to shadcn/ui, legacy stores to TanStack Query, Pages Router to the Next.js App Router.
    • Ship mobile appsCross-platform React Native with offline-first state, push notifications and payments.
