Hire the Best Lotus Notes Developers

I help founders and small teams turn messy workflows, fragile automations, spreadsheets, and AI-built prototypes into reliable web and mobile apps that are ready for production use. I’m a full-stack no/low-code architect with 18+ years of IT experience. I work at the intersection of product, data architecture, automation, and implementation: I clarify the workflow, choose the right stack, build the system, explain trade-offs, and help prevent expensive structural mistakes. 𝐖𝐇𝐄𝐍 𝐈’𝐌 𝐀 𝐆𝐎𝐎𝐃 𝐅𝐈𝐓 • Scale & Stability: Your current Airtable, Bubble, Glide, Lovable, Claude/Cursor, or AI-generated setup is becoming fragile, messy, or hard to maintain. • Production Systems: You need a SaaS MVP, client portal, internal tool, mobile companion app, CRM/workflow automation, or AI-powered product that must be stable, maintainable, and ready for daily operations. • Fractional CTO / Technical Partner: You need someone to own the architecture, document the system, coordinate developers/vendors, and guide technical decisions beyond pure development. ⚠️ 𝗡𝗼𝘁 𝗮 𝗳𝗶𝘁: I’m not the best fit for cheap one-off fixes or pure task execution. 𝐓𝐄𝐂𝐇𝐍𝐈𝐂𝐀𝐋 𝐒𝐓𝐀𝐂𝐊 🧱 𝗣𝗿𝗶𝗺𝗮𝗿𝘆 𝗦𝘁𝗮𝗰𝗸: WeWeb + Supabase + n8n for serious web apps, SaaS products, internal tools, and automation-heavy systems. 📲 𝗠𝗼𝗯𝗶𝗹𝗲 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: FlutterFlow as a mobile frontend connected to the same backend and automation layer. 🧰 𝗔𝗹𝘁𝗲𝗿𝗻𝗮𝘁𝗶𝘃𝗲 𝗦𝘁𝗮𝗰𝗸: Bubble, Xano, Glide, Softr, Airtable, Make, Zapier, Webflow, Figma, Docker. 🛠️ 𝗖𝗼𝗱𝗲 & 𝗔𝗜: Vue.js, JavaScript, Python, SQL, APIs, Claude Code, Cursor, Codex, Lovable. 𝐃𝐄𝐄𝐏 𝐖𝐄𝐖𝐄𝐁 & 𝐒𝐔𝐏𝐀𝐁𝐀𝐒𝐄 𝐄𝐗𝐏𝐄𝐑𝐓𝐈𝐒𝐄 I go beyond standard no-code assembly. I build custom Vue.js components, manage complex frontend states, design clean frontend/backend boundaries, and structure backends with PostgreSQL, RLS, auth, Edge Functions, SQL workflows, and disciplined SQL versioning. I fix projects where typical no-code or AI-built systems start to break. 𝐓𝐘𝐏𝐈𝐂𝐀𝐋 𝐄𝐍𝐆𝐀𝐆𝐄𝐌𝐄𝐍𝐓𝐒 • Apps & Portals: Web apps, SaaS MVPs, client portals, internal tools, and mobile companion apps. • Infrastructure Cleanup: Stabilizing and refactoring rushed AI-built, low-code, or spreadsheet-based products. • Automations & Backends: n8n/Make/Zapier workflows, secure Supabase databases, CRM integrations, webhooks, and API-based systems. • Tech Leadership: Fractional CTO support, architecture reviews, product/technical trade-offs, documentation, and handoff. 𝐄𝐍𝐆𝐀𝐆𝐄𝐌𝐄𝐍𝐓 𝐌𝐎𝐃𝐄𝐋 I bring the most value to business-critical, messy, or fast-growing projects that need architecture before implementation. Clients work with me because I can both build and advise — and because I’m comfortable calling out shortcuts that may look cheap now but become expensive later.
