What I'm looking for

I’m looking for n8n and automation projects where I can design and deliver production workflows, integrate APIs and LLMs, and make new AI use cases reliable through testing, validation, and guardrails. I’m available for remote contract work from Cyprus.

I build and maintain production automations with n8n, APIs, webhooks, Python, and LLMs. At Perspektiva LLC, I automated processes across sales, fulfilment, support, and finance; around 12 services ran around the clock for a business that grew to €2M annual turnover.

As an independent n8n / Automation Developer, I scoped and delivered client systems, including a WhatsApp lead-qualification funnel using Claude API and PostgreSQL, with escalations to human agents via Telegram. I also delivered an inspection-report bot and traffic-fine monitoring for a vehicle fleet.

I run the technical stack myself, from self-hosted n8n and Linux VPS operations to PostgreSQL, Redis, and workflow monitoring. I’m interested in turning practical automation and AI use cases into reliable tools, with testing, validation, and guardrails built into the work.
