Stefan O.
Last position:
Founder at ProtocolEngine.io
Evidence-led health intelligence platform turning published research into personal health protocols. It scores 430 habits, foods, and supplements against the studies behind them, and moves the score when the evidence moves. Built solo.
- Built the daily ingestion pipeline across PubMed, bioRxiv, and medRxiv: 43,000+ papers from 3,400+ journals processed into 230,000+ typed evidence claims, each one traceable back to the study it came from.
- Designed the six-factor evidence scoring model and the public changelog behind it, so no recommendation ever appears without the papers underneath it. 23,000+ grade changes recorded and explained to date.
- Shipped an entity information model connecting every intervention to its mechanisms, biomarkers, and outcomes: 118 biomarkers with region-specific reference ranges, 77 mechanisms, 32 graded outcomes.
- Built the personalisation layer: blood panel ingestion that reads lab PDFs with a vision model and corrects results for draw time against the user's wake anchor, plus Oura, WHOOP, and Withings integration for daily readiness context.
- Operate eleven specialised review agents over the corpus and codebase, covering paper curation, retrieval quality, health-claim compliance across EU and US regimes, and security.
- Shipped the Evidence Assistant, a RAG assistant that answers from the claim database and cites the underlying papers, plus a B2B practitioner tier, an Expo React Native app, and localisation across 3 languages and 7 markets.
Stack: Next.js 16, TypeScript, Supabase, pgvector, Anthropic Claude, Vercel, DeepInfra.

- Designed and shipped a multi-agent AI system using ReAct framework and Claude skills-style workflow patterns, including an intelligent PM assistant with rich system prompts, slash commands, tool integrations, and streaming chat UI.

- Integrated LangFuse for end-to-end LLM tracing, conversation replays, and evaluation pipelines, enabling data-driven prompt optimisation that reduced token costs and response variance.
- Built with Drizzle ORM, pgvector, and knowledge graphs for structured data access, semantic search, and relationship-aware AI reasoning across the platform.
- Led TanStack React Query migration across the application — replacing manual state management with centralised caching and automatic refetching, reducing data-fetching boilerplate significantly.
- Practiced AI-native development throughout: Claude Code, Codex, Perplexity SDK, and LLM-assisted testing across the full development lifecycle. Deployed on Vercel + Azure ACA with Biome for linting/formatting.

About the technology
What Vercel does
Vercel is a cloud platform for building, deploying and scaling modern web applications. It is closely associated with Next.js and supports frontend projects that need fast delivery, global content distribution and streamlined releases. Teams use it for marketing sites, ecommerce experiences, customer portals and SaaS interfaces.
Core capabilities
Vercel combines source control integration, preview deployments, serverless and edge execution, managed domains, observability and automated production releases. Its platform handles build pipelines and content delivery while teams retain control over application code and project configuration. Strong specialists understand how these pieces affect performance, security and maintainability.
Ecosystem and tooling
The Vercel ecosystem commonly includes Next.js, React, TypeScript, Node.js, Git-based workflows and headless content systems. Specialists may also work with Vercel Functions, Edge Runtime, Middleware, Preview Deployments, the Vercel CLI and the platform API. They connect these tools with databases, authentication services, payment systems, analytics and external APIs.
Where companies use it
- Launching SEO-focused websites with fast preview cycles
- Delivering ecommerce storefronts and personalized content
- Running server-rendered or statically generated Next.js applications
- Creating edge-aware APIs, forms and lightweight backend services
- Migrating frontend delivery from self-managed infrastructure
Vercel fits product teams that need a short path from a committed change to a reviewable deployment. In Berlin, specialists may support local product, media, retail and software companies through remote or hybrid collaboration.
When freelance expertise helps
Companies bring in freelance expertise when an existing application needs a careful migration, a performance improvement or a dependable release setup. Specialists can establish preview and production environments, configure domains and environment variables, connect external services, and diagnose build or runtime failures. They are also useful when internal teams need focused support before a launch or handover.
What strong specialists bring
Good Vercel specialists look beyond a successful deployment. They can explain rendering choices, caching behavior, image and asset optimization, runtime limits, access controls and rollback plans. They document configuration, protect secrets and create a workflow that the internal team can operate after delivery. Clear English is usually essential for distributed work; German can add value in Berlin-based collaboration.
Frequently asked questions
Key details about Vercel, drawn from the questions we get asked most.
Vercel is used to deploy and operate modern web applications, especially projects built with Next.js and React. It supports preview environments, server-side rendering, static generation, edge delivery and serverless functions without requiring a team to manage the full delivery infrastructure.
Vercel is often chosen for its close integration with Next.js, simple preview workflow and opinionated deployment experience. AWS offers broader infrastructure control, while Netlify and Cloudflare Pages provide overlapping web delivery features with different runtime, networking and ecosystem strengths.
A strong Vercel specialist usually understands Next.js, React, TypeScript, Git and web performance. Depending on the project, useful adjacent skills include headless CMS integration, database access, authentication, CI/CD, observability, SEO and secure API design.
The right Vercel experience depends on the project scope rather than the platform alone. A content site may need strong deployment and frontend knowledge, while a large application can require expertise in rendering strategy, caching, edge behavior, security, integrations and production operations.
Vercel supports remote collaboration through pull requests, preview deployments, shared project settings and clear release workflows. Berlin-based companies can work effectively with remote specialists when access, ownership, communication language and handover expectations are defined early.
A Vercel setup may be less suitable when a project needs highly specialized infrastructure control, unusual long-running workloads or strict requirements around where every workload operates. A careful assessment should cover runtime limits, data location, networking, costs and operational responsibilities before migration.
Ask a Vercel specialist to explain a comparable delivery workflow, including previews, environment variables, caching, monitoring and rollback. Quality is visible in practical trade-off discussions, secure configuration, readable documentation and the ability to leave the team with an operable setup.
Vercel supports frameworks beyond Next.js, including other React-based and static-site approaches. Specialists should be able to explain when the chosen framework benefits from Vercel features and when a different deployment model would better match the application.
