I ship LLM-powered features in production: custom agents, automation pipelines and clean web apps. No hype, working code.
Five concrete offers, from LLM integration to solid full-stack work.
Domain chatbots, internal assistants, specialized agents with RAG. I design, build and ship full AI apps wired into your data and systems. Auth, permissions, observability, cost control. Stack: TypeScript, Next.js or Astro, Postgres, pgvector or Qdrant, Claude and GPT.
Adding AI features to an existing SaaS or app: suggestions, generation, classification, extraction, semantic search. Streaming, retries, multi-provider fallback, caching, per-user budgets. I plug in OpenAI, Anthropic, Mistral or self-hosted open-source models depending on constraints.
Multi-step workflows that replace manual tasks: document parsing and classification, structured scraping, PDF and email extraction, cross-tool sync. Robust orchestration, queues, retries, readable logs. N8n or custom code depending on volume.
When you just need a solid developer. SaaS, dashboards, APIs, client portals, back-offices. Modern stack: TypeScript, Next.js, Astro, Node, Postgres, Cloudflare. Clean deploys, simple CI, monitoring. No over-engineering.
For SMEs that want to start without getting trapped by hype. I review your processes, spot the use cases that pay off, and tell you what is worth it and what is not. Deliverables: summary note, prioritized roadmap, cost and ROI estimates.
