Hire the Best Salesforce Experts
in Portugal

I build complete products end to end, solo: PostgreSQL schema, typed API (tRPC), React or React Native frontend, AWS infrastructure as code, keyless CI/CD, custom domain, and TLS. 6+ live products run on a serverless platform I designed and reuse, and my recurring infra bill trends toward $0 by deliberate cost engineering: a documented S3-outbox relay pattern that replaces NAT gateways, free-tier tuning, and Durable Object hibernation. I am also an AI/LLM engineer in the strong sense: multimodal apps (vision + voice + RAG with pgvector), multi-provider orchestration (Anthropic, OpenAI, Gemini), LangGraph agents, LLM-as-judge evals, and an open-source agent framework I built on the Claude Agent SDK + Model Context Protocol: 20 agents, 47 skills, and 10 MCP tools that autonomously design, implement, and verify code behind human gates. Don’t trust the portfolio. Test me. Two ways: 1. AI briefing pack. Ask me for it, paste it into your own ChatGPT or Claude, and let YOUR AI evaluate my credentials. It is distilled from an automated audit of 26 of my real repositories and includes what I am still improving, because an honest document is more useful to you than a polished one. 2. Prompt challenge, free, one round. Send me a realistic prompt from your project: feature spec, bug report, or architecture question. I return the output of my AI-assisted workflow plus my human review: what I kept, what I corrected, and why. You judge the result and the judgment. Stack keywords: TypeScript, React 18/19, Next.js, Expo/React Native, tRPC, Drizzle, PostgreSQL, Supabase, AWS (Lambda, SAM, API Gateway, RDS, DynamoDB, CloudFront, Cognito), Cloudflare (Workers, Durable Objects, Pages), GitHub Actions OIDC, Clerk, LangGraph, Claude Agent SDK, MCP, RAG, Godot 4, n8n, Make, Zapier. Portfolio item blurbs Xenodot Forge (open source, MIT) = AI game-dev framework on the Claude Agent SDK + MCP: a human-gated design → implement → verify agent pipeline (20 agents / 47 skills / 10 MCP tools, ~14.7k LOC) driven from a WebSocket UI, with a verification-first quality gate (headless engine checks, zero-warning lint, CI-enforced validators). Used it to build a playable cross-platform 3D FPS in Godot 4.6. Available on my GitHub. Probius.app (live EdTech) = Study platform for the Brazilian OAB bar exam. React + Vite SPA on S3/CloudFront, Lambda + tRPC + Drizzle + PostgreSQL, NAT-less VPC posture with all outbound AI/email traffic via an S3-outbox relay, deployed exclusively through keyless GitHub Actions OIDC. Multimodal AI mobile app (~28k LOC) (3itch ai) = Fashion-critic app: Expo client, tRPC-on-Lambda backend, Cloudflare Durable Objects realtime engine. Vision (Gemini), persona brain (GPT-4o), voice in/out (Whisper + TTS), wardrobe RAG (pgvector), per-user AI spend caps, offline RS256 JWT verification on both backends, and gitleaks in CI. Production e-commerce (~31k LOC) = Luxury-furniture platform: Next.js 16 SSG storefront, React admin SPA, serverless API, and one PostgreSQL backend. Infra cost cut to ~$0 with the S3-outbox relay pattern, plus a single-query JSONB product search function that eliminates N+1 fetches. Multi-tenant PMS + OTA sync = Vacation-rental management system with Channex integration to Airbnb and Booking: idempotent booking sync, SQS worker queue, EventBridge polling, and a 12-scenario automated certification suite. Prompt Challenge I will run your prompt through my AI engineering workflow and hand you the reviewed output. Description: Send me one realistic prompt from your project: a feature spec, bug report, refactor, or architecture question. I run it through my AI-assisted workflow, using the same agent tooling I open-sourced, and deliver: (1) the raw output, (2) my line-by-line human review marking what I kept, what I corrected, and why, and (3) a short note on how I would productionize it. This shows you what you are actually hiring in 2026: not “can he prompt an AI,” but “can he judge, correct, and ship what the AI produces.” First round free on invite.

Over a decade in operations and people management across AI data projects, multinational environments, and remote teams. I build structure where there isn’t any – process documentation, workflow design, onboarding architecture, and operational coordination for growing teams. I work particularly well in async, evolving environments where the priority is creating clarity, reducing friction, and making sure things don’t fall through the cracks. My experience includes: • Operations and workflow design for AI and language-focused projects • Process documentation, SOPs, and knowledge management • CRM organization and relationship tracking • Project coordination and cross-functional collaboration • AI-assisted research and documentation using Claude and ChatGPT • Localization and cultural adaptation for European Portuguese I’m based in Portugal, fluent in English, and comfortable working across time zones in fully remote setups. If you’re a team that needs someone organized, autonomous, and genuinely invested in making operations run better – let’s talk.

👉 I build AI automation systems that eliminate operational waste. Clients typically recover $100K–$500K/year in hours, errors, and tool sprawl once the systems are running. Top 1% Expert-Vetted on Upwork. 100% Job Success Score. Every project, every time. —— 𝗪𝗵𝗼 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵 You are likely the right fit if any of these sound familiar: ● Your team is doing the same manual steps dozens of times a week ● Your tools don't talk to each other and nobody owns the gap ● You have automations running but nobody knows how they work or what breaks them ● You are growing but your ops are not keeping up If you are looking for the cheapest option or a quick fix, I am not your person. If you want systems that actually hold up, keep reading. —— 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀 & 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 End-to-end systems built on Claude, n8n, and Make that replace manual handoffs, route data intelligently, and run without supervision. If I cannot tie the automation to a clear ROI — hours saved, errors reduced, revenue recovered — I will not build it. 𝗖𝗥𝗠 & 𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻 Your CRM, billing, support, and internal tools aligned and self-updating. Lead routing, follow-up sequences, approval flows, and real-time dashboards — built on rules your team can actually read and change. 𝗔𝗜-𝗽𝗼𝘄𝗲𝗿𝗲𝗱 𝗜𝗻𝘁𝗲𝗿𝗻𝗮𝗹 𝗧𝗼𝗼𝗹𝘀 Custom agents that pull from your actual company data. Document processing, RAG pipelines, internal assistants, and automated reporting — so your team stops hunting for answers and starts acting on them. —— 𝗧𝗲𝗰𝗵 𝘀𝘁𝗮𝗰𝗸 Claude, n8n, Make, Zapier, OpenAI, Python, REST APIs, Airtable, HubSpot, Salesforce, Pipedrive, GoHighLevel, ClickUp, Notion, Google Workspace, Supabase, Webhooks —— 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I think in systems, not tasks. Before touching a single tool I map where your time and money are actually leaking, then build the highest-ROI fix first. Everything I deliver comes with documentation and a video walkthrough so your team owns it — not me. Most engagements start with one process and expand from there. Not because I upsell. Because once the first automation runs, the next bottleneck becomes obvious. —— 𝗡𝗲𝘅𝘁 𝘀𝘁𝗲𝗽 Send me one line about your biggest operational headache. I will tell you within 24 hours whether it is worth automating and what the build would look like. No pitch. No pressure. Just a straight answer.

Most n8n and AI automation projects fail within 90 days - built fast, not built right. We're 2V Automation, a 30-person team and n8n Certified Expert Partner, building production-grade AI agents, workflows and API integrations for SMBs, agencies, and service businesses that survive past month three. I'm Valerian. I run 2V Automation, a 30-person team. We do AI and workflow automation for service businesses, and we do it the way most don't. ENGINEERING DISCIPLINE OVER VIBES 20 years of writing software before AI was a marketing category. We treat automation like production code: error handling, logging, alerts, version control, real testing. Not "it worked when I clicked run". SIMPLE BEFORE CLEVER The shortest workflow that solves your problem is almost always the right one. Each new node is another point of failure, another paid API, another thing your ops team won't understand in 6 months. We push back when clients ask for the complicated version. DISCOVERY FIRST, ALWAYS Most clients want to "automate everything". Almost nobody actually needs that. We do focused discovery (2-3 weeks, fixed fee), find the 3-5 places where automation pays back fast, and propose a phased plan. You keep the document whether you continue or not. PILOT BEFORE BUILD-OUT Whatever discovery surfaces, we ship the single highest-ROI piece first. If the pilot doesn't pay back, the next phases probably won't either. Better to find that out in week 6 than month 12. CREDENTIALS $1M+ delivered on Upwork. 14,912 hours. 100% Job Success. Top Rated Plus. n8n Certified Expert Partner. A real team: engineers, PMs, designers, QA. Not a solo founder with a Loom video. WHO THIS IS FOR 10-200 person service businesses (consulting, agencies, finance, professional services). Founders and operators who've done the math on what manual work is costing them and are ready to fix it properly. WHO IT ISN'T FOR People shopping on price. People who want "an AI that runs everything by Friday". People who've already decided what should be automated and just need hands. We're not those hands. If you're the first kind, send me a paragraph: What your business does, what's broken or expensive. I'll tell you within a day whether discovery is worth doing.
