Top Rated Plus on Upwork. $70K+ earned, 100% Job Success, 3,500+ hours across 3 multi-year retainers. I build vertical SaaS for construction, real estate / PropTech, logistics / 3PL, and AI / RAG SMB tools, on Next.js, Node, TypeScript, and Postgres. That first line is the pitch. Here's the proof. Shipped: • TheBuildTrack: construction management SaaS with dynamic punchlists, daily logs, bid packages, and subcontractor portals. Cut project coordination time by ~70%, 20+ active projects. • AllAmericanWarehouses: commercial real estate platform with interactive property search, CMS-driven content, and lead capture. 60% faster lead conversion, 80% less admin overhead, 8-week build. • Ship Stampede: logistics / 3PL workflow tooling, live carrier rates, label printing, Shopify / Amazon / Cin7 integrations. Currently fractional CTO. • QuickChat / Zesty / 500 Designs RAG work: AI documentation and support over retrieval-augmented search with sub-2-second response times in production. Stack: Next.js, React, React Native, Node.js, TypeScript, PostgreSQL, Prisma, Tailwind. Currently Engineering Team Lead at Bee Techy LLC and founder of Medianeth Solutions, so I bring team-tested architecture, not solo-dev shortcuts. How I work: • One client at a time. When you hire me, you get a dedicated engineer, not a generalist juggling four jobs. • I own the build end-to-end: schema, API, UI, deploy, post-launch. • I write to non-technical founders the same way I write to CTOs. Plainly. Best fit if you: • Have a vertical SaaS stuck between MVP and v2, or a stalled internal tool with real users. • Need someone who already speaks construction, real estate, logistics, or RAG instead of learning your domain on your dime. • Want a 30 to 90 day engagement with a clear scope, not a forever retainer. Not a fit for: WordPress builds, no-code prototypes, or agency white-label work. Free 30-minute scoping call before any commitment. Send me the problem you're trying to solve and I'll respond within 24 hours.

I build production iOS apps (SwiftUI, Swift 6) and official WhatsApp Cloud API backends (Meta + Firebase) for restaurant ordering and real-estate viewing booking. I’m the co-founder and developer behind MIRA, an AI-native music assistant in public TestFlight (ElevenLabs Conversational AI, LiveKit, StoreKit 2, Google Cloud Run / Python). I also ship Comanda — hands-on WhatsApp restaurant/café ordering with interactive menus, kitchen tickets, and pickup map pins (live Café del Óvalo demo in my Portfolio) — and Aparta — WhatsApp listing FAQ, in-chat viewing booking, and agent alerts for agencies and landlords (live Casa Condesa demo in my Portfolio; US/CA add-ons: Follow Up Boss, BoldTrail, Google Calendar). What I help clients build, fix, or ship: • WhatsApp Cloud API: Meta webhook + HMAC, interactive menus or listing FAQ, kitchen/agent notify, Firebase. I provision and host the line, or wire Cloud API on your number. • Real estate WhatsApp (Aparta): property answers + photos, in-chat viewing booking, agent ping; optional Follow Up Boss, BoldTrail listing sync, and Google Calendar write. • In-App Purchases: StoreKit 2 subscriptions, paywalls, and Firestore credit quotas. • AI & realtime: ElevenLabs Conversational AI, LiveKit, or custom REST APIs in native SwiftUI. • Google Cloud & GenAI: Firebase Auth, Firestore, App Check, Python on Cloud Run, Vertex AI (Imagen, Gemini, Veo) when the product needs it. • Modern SwiftUI & media: production UI, AVFoundation playback/export, and sharing SDKs. My approach: I use Cursor and AI-assisted workflows to move fast: audit codebases, clear App Store blockers, and ship clean production code. Same discipline on Meta/WhatsApp — honest Cloud API setup, not unofficial scrapers or one-click “install app” fantasies. Available for quick fixes, feature sprints, and fixed-scope WhatsApp setups for restaurants (Comanda) or agencies & landlords (Aparta). See my Project Catalog. Test MIRA via the public TestFlight link in Portfolio. Try the live WhatsApp demos from the Portfolio project links: Café del Óvalo (Comanda) and Casa Condesa (Aparta) — no need to message me first.
