Product Engineer. AI-First Builder.
I design and build full-stack AI applications from architecture to deployment. Currently building Syncd Health: a voice-first mental health AI with streaming architecture, multi-layer safety systems, and GDPR-ready infrastructure. Product thinking, real engineering, AI-augmented development.
Client Testimonial
What clients say
What stood out to me was how engaged Ricki was. He consistently brought ideas to the table and was proactive in supporting different teams when technical questions came up.
When Ricki worked with us at Shibari Study as Interim CTO, he was particularly involved in building out our Notion workspace with dashboards, templates, and documentation that helped us organize internal processes more clearly. He also contributed to the implementation of tools like Slack and Google Workspace, helping us move toward a more centralized and professional setup.
Ricki combines strong curiosity about systems and tools with a collaborative approach to working with teams, and he genuinely enjoys helping organizations structure their workflows and processes.
What I've Built
Syncd Health
CTO & Co-Founder, currently building
Voice-first AI companion for people on therapy waiting lists. Full-stack application built with AI-augmented development, designed for the German healthcare market.
AI Pipeline
Real-time streaming via Vercel AI SDK and Vertex AI. Dynamic model routing between Gemini Flash and Pro based on request complexity.
Safety Systems
Multi-layer crisis detection with German language support and confidence scoring. Input-side safety checks with observability-layer quality monitoring.
Voice
Google Cloud Speech-to-Text with real-time audio streaming pipeline. Voice-first UX with text fallback.
Security & Compliance
Designed for GDPR compliance with EU data residency. Supabase Row-Level Security, CSRF protection, end-to-end safety testing.
Multi-Source Data Pipeline
Own project, in production
Data aggregation system processing 700+ records from 6 sources with automated scoring, cross-source deduplication, and real-time Telegram alerts. FastAPI service on Railway, PostgreSQL with custom triggers, scheduled workflows with daily summaries.
Result: production system running daily since February 2026 with minimal manual intervention.
Shibari Study
Interim CTO, 7 months
Took over a struggling dev team, stabilized the codebase, shipped the product. Built API integrations with Uscreen, Mailchimp, and Facebook solo after the lead developer left. Then restructured how the team works:
- Moved team communication from scattered WhatsApp groups to a structured Slack workspace
- Migrated from Dropbox to organized Google Drive with professional Google Workspace
- Unified project management from separate Trello boards to centralized Notion dashboards
- Documented everything and onboarded a replacement developer for handoff
Result: less chaos, clearer processes, a team that could operate independently.
How I Build
I build with Claude Code as my primary development environment. Architecture, engineering, testing, deployment, all through AI-augmented development.

Product engineer based in Berlin. I studied Business Informatics at HWR Berlin, trained in UX/UI Design at SPICED Academy, and spent 2.5 years in web development at KPMG.
As Interim CTO at Shibari Study, I led a team through a product crisis, built API integrations solo after the developer left, then rebuilt operations from the ground up. Now I build AI applications full-time as CTO and co-founder of Syncd Health, part of Startup Incubator Berlin.
My primary development environment is Claude Code. I use AI-augmented development for everything I build.
