I build AI-powered automation systems that quietly eliminate manual work so your team focuses on what actually needs a human. No fragile Zapier demos. No bolted-together MVPs. Production ready infrastructure that compounds: AI agents, Python back‑ends, and n8n workflows that handle the ugly edge cases. What I do AI Agent Development & LLM Orchestration: Multi‑step autonomous agents that handle client communications, document processing, approvals, and reporting. Deep prompt engineering so agents actually understand your business. Back‑End Automation & Python Systems: FastAPI, PostgreSQL, and custom Python scripting for when no‑code hits its ceiling. Clean, documented, maintainable code built for production. Workflow & CRM Automation: End‑to‑end n8n / Make pipelines, Google Workspace & API integrations, marketing automation, and task automation that keep your CRM and operations flowing silently. Who I work with Founders and ops leaders scaling teams where spreadsheets and manual handoffs are now a bottleneck. You need systems that survive week two and keep getting smarter. How I work When you reach out, I don’t send a template. I’ll reply with a personalised Loom video, walking through exactly how I’d tackle your bottleneck. Once we kick off, I’m incredibly communicative; You’ll get daily updates, so you always know what’s happening and what’s next. At handover, you won’t be left guessing: I deliver full documentation PDFs and walkthrough Loom videos explaining how every system works. That’s non‑negotiable for me; I make sure your team can own and operate everything confidently, long after I’m done. Send me a message, and I’ll prove it in the first reply.

Over 8 years we have helped startups and product companies build software that scales, from first prototype to Series B. More than 45 products shipped across Healthcare, LegalTech, SaaS, E-Commerce, and Transport. Our AI engineering team builds production systems, not research demos. We design agent architectures, RAG pipelines, and AI workflows using TypeScript (Mastra, Vercel AI SDK) and Python (LangGraph, Agno, Pydantic AI, LangChain). We work with Claude, OpenAI ChatGPT models, Gemini, and open-weight models (including GLM, Kimi, DeepSeek and many more), choosing based on task fit and cost constraints. We practice eval-driven development. Automated eval pipelines, LLM-as-judge scoring, quality gates, all of that runs before anything ships to production. We build MCP integrations and custom Agent Skills, implement structured outputs with guardrails, set up agent observability with tracing, and design context architectures so models get the right information at every step. We have delivered domain-specific AI assistants with RAG and ongoing eval monitoring, agentic tools with multi-step reasoning and tool use, legal document processing at 95% accuracy, AI data aggregation with automated validation, voice agent systems, and generative UI products. Our full-stack team supports AI products with solid web infrastructure: React, Next.js, Vue.js, TypeScript, Node.js, GraphQL, and REST APIs. We deploy on AWS, GCP, and Vercel, and work with PostgreSQL, Redis, and vector stores (Pinecone, Qdrant, pgvector). For mobile we use React Native and Flutter. Delivered results: RAG-powered support bot reduced resolution time by 70% and lifted NPS by 20%. AI event aggregation pipeline scaled B2B SaaS onboarding from 1 to 5 clients per month at 95% data quality. LLM document system cut legal research from days to hours. AI landing page builder matched agency-level output with zero designer involvement. First-year ROI across AI projects averages 3.2x. We have built AI systems for LegalTech (tax advisory, contract analysis), Healthcare (medication search with voice agents), Transportation (fleet management, real-time optimization), E-Commerce (content generation), SaaS platforms with AI-native features, and B2B products with intelligent data pipelines. Our clients are startups embedding AI into their product, and companies replacing manual workflows with intelligent automation. We cover the full cycle: discovery, architecture, development, eval pipeline setup, deployment, and ongoing optimization.
