You will get a production-ready n8n workflow built for your business
Project details
I build production-ready n8n workflows that actually run in production — not demos that fall apart on the first edge case. Error handling, retry logic, branching, and AI integration where it adds value.
What you get
• 1 production-ready n8n workflow (you own the JSON)
• Inline docs on every node
• Proper error handling + retry logic
• 1-hour handoff call to install + train your team
Who this is for
• Founders/operators who want to stop doing repetitive multi-tool tasks by hand
• Teams that tried n8n templates but need a senior engineer to make them production-grade
• Companies layering AI into existing workflows (lead enrichment, content pipelines, support triage)
What I bring
17 years of software engineering. Built an autonomous A/B testing agent that runs 6-tool workflows end-to-end in ~15 minutes. Daily power user of Claude Code, MCP, and orchestration patterns. I know what breaks in production.
NOT included
• Hosting setup beyond initial install
• Long-term maintenance (separate retainer)
• Discovery of tools/integrations you don't yet have
How to start
Order the project. Quick call to lock the workflow spec, then I build.

Proof of Concept - for Ninja Mochi
I dont know, we had lots of miss-communication, and I don't know who is at fault, me or the developer and his team, From my side - they added team members who had not been briefed, changed and removed team members, and didn't follow the instructions - when New team members were added to the project, and then not briefed - The only way I could get updates was by chasing the team for information - and that didn't work - and then -new people were added to the project who wanted to change the agreement - I had to chase down for results status updates, and it was clear that we had not understood each other and were talking about completely different projects. - I asked them many times to negotiate an ending - and their response was they felt they had provided their service - I was unable to use a single record they provided and there was no discernable methodology that would have helped me

this is a flawed system. We never worked together. Sorry to the freelancer and I hope upwork can simply discard this contract as it never started. 0 hours.

About Andrei
AI & Software Engineer | MCP, Agents | TypeScript, Python, Swift, Go
Chisinau, Moldova - 8:26 am local time
17 years building production systems end-to-end — from first commit to scale
What I do best —
I take complex systems from idea to production: AI agents that run end-to-end workflows, browser-native automations that survive at scale, full-stack SaaS that handles real load, and native apps that ship clean. I'm hands-on across the entire stack — frontend, backend, infra, data, mobile, and increasingly the deep stuff: forked browsers, on-device AI, post-quantum cryptography.
I work fast, scope tight, ship clean. No hand-holding required.
Where I'm strongest —
AI Engineering: Claude Code, MCP Servers, Skills, Commands, AI Agents, Anthropic API, OpenAI API, Prompt Engineering, n8n, Workflow Automation, Multi-tool Pipelines
Full-Stack Engineering: TypeScript, Node.js, Python, Go — React, Next.js, Tailwind CSS — REST APIs, GraphQL, WebSocket, Microservices — PostgreSQL, Citus, Redis, MongoDB, NoSQL, SQL — Custom Queues, Message Queues, RabbitMQ — Cypress, A/B Testing, SSR/ISR, Core Web Vitals, Performance Tuning
Cloud & DevOps: Kubernetes, Cloudflare Workers / D1 / R2, Terraform, Helm Charts, Prometheus, Docker, GitLab CI, CI/CD, DigitalOcean, OVH, Linux
Browser-Native & Automation: Chromium (native C++ SDKs), Browser Automation, Headless Browsers, Anti-Bot Detection, Web Scraping, Fingerprinting, Proxy Networks, Scrapy, Selenium, Puppeteer
Mobile & Desktop: Swift, iOS, Kotlin, Android, React Native, Electron.js, Desktop Application Development, macOS
Edge & On-Device AI: Edge Computing, llama.cpp, On-Device LLMs, Edge Inference
Cryptography & Distributed Systems: Ed25519, X25519, Post-Quantum Cryptography, X3DH, PQXDH, Double Ratchet, Megolm, P2P Networking, Distributed Systems, Kademlia DHT, WebRTC, QUIC
How I work —
I architect first, then ship. I write specs when scope is unclear. I bring receipts: dashboards, metrics, working demos, not promises. I communicate async, deliver under tight deadlines, and don't disappear mid-project.
Senior contracts only —
Agents, MCP servers, SaaS platforms, native iOS, browser-native automation, distributed systems, edge AI.
Remote-first. CET timezone. English, Romanian, Russian: fluent in all three.
Available now. Send scope, timeline, and engagement type and I'll respond with a clear plan.
Steps for completing your project
After purchasing the project, send requirements so Andrei can start the project.
Delivery time starts when Andrei receives requirements from you.
Andrei works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery + workflow spec
30-minute call to confirm the trigger, systems involved, branching logic, and desired outcome. I write a 1-page workflow spec with node-by-node breakdown for your approval before building.
Build + test
I build the workflow in n8n with proper error handling, retry logic, and inline docs on each node. Each path tested end-to-end with sample data. Delivered as an importable JSON.
