I help startups, SMEs, and operationally complex businesses modernize how they run — through AI automation, intelligent workflows, and engineered systems built for scale. My focus is operational transformation: replacing manual, fragmented processes with integrated, AI-driven systems that compound efficiency over time. I work with founders, operators, and agency leaders who need execution that thinks beyond code — combining engineering depth with a clear understanding of how businesses actually function. Where I focus: — AI Workflow Automation & Business Process Automation Designing AI-powered automations across CRMs, internal tools, and operational stacks. Built with n8n, Make, Zapier, and custom Node/Python services. Outcomes typically measured in hours reclaimed per week and manual errors eliminated. — AI Agents, LLM Integrations & Intelligent Systems Production-grade AI agents and integrations — RAG pipelines, tool-use, retrieval, evaluation, and guardrails. Built on OpenAI, Anthropic Claude, LangChain, and vector databases. Architected to behave reliably, not just demo well. — Internal Tools, Dashboards & Operational Software Custom admin panels, operational dashboards, internal CRMs, and team-facing systems that consolidate fragmented SaaS stacks into one well-engineered platform. — Modern Full-Stack Engineering Production web applications and SaaS systems engineered for scalability and long-term maintainability. Next.js, React, Node, Python, TypeScript, PostgreSQL, Supabase, AWS. How I work: Every engagement starts with a short discovery, a clearly scoped approach, and defined outcomes — not a feature list. I work in structured phases with regular checkpoints, deliver documentation as part of every build, and offer optional retainer arrangements for ongoing iteration after handover. Best fit for businesses that view software and automation as operational infrastructure, not one-off tasks. Engagements range from focused 2–3 week builds to multi-month transformation projects and ongoing technical partnerships. If you're scaling operations, adopting AI seriously, or rebuilding how your business runs — send a short brief. I'll respond with a scoped approach and any questions needed to quote accurately.
