What's rare is a developer who is also a designer, and who actually ships. I have 6 apps live on the App Store under my own name. I designed, built and published every one of them end to end: - HMU: hit me up. Anonymous messaging with two way replies. iOS app + web app (heyhmu.link) - Left on Read: Texting Stories. Interactive chat fiction where AI plays the other side of the conversation - Om: Bhagavad Gita & Kundli. Subscription app with scripture, astrology charts and live streams - Hindu Mode: Pray Before Scroll. A Screen Time blocker built on Apple's FamilyControls APIs - Couple Lock: Love Then Scroll - Edition: Curated Designs On the web: isitover.app, an AI chat analyzer (Next.js, Vercel, LLM pipeline, payments, transactional email). What I work in: - iOS: SwiftUI, StoreKit / RevenueCat subscriptions and paywalls, FamilyControls, on-device Vision and Core ML, TestFlight and App Store review - Web: Next.js, React, TypeScript, Supabase / Postgres, Vercel, payments, email - AI: OpenAI, Claude and Gemini APIs, agents and tool calling, RAG, OCR, prompt design, keeping AI costs sane in production What you get working with me: - One person, one vision. No handoff gap between the designer's file and what got built. - Design led development. I start with how it should feel, then engineer backward from there. - Honest scoping. I'll tell you what's worth building first, and what isn't. - I've been through App Store review many times, so launch day isn't a surprise. Anyone can make it work. I make it work and make people want to use it. menos -

I also repair and finish systems that other people started. I handle the full process: design, development, content, and launch. That means fewer handoffs, less waiting, and clearer responsibility. Before I build, I ask the questions that prevent rework. What does the system need to do? Where does the content come from? What data needs to move? Who will maintain it after launch? Then you get almost no rework. I show you the work at each step, and I tell you about a problem early, not after the budget is gone. For many businesses, WordPress or Shopify is the right choice because your team can manage day-to-day changes without a developer. For larger systems I write custom code. I also connect tools and automate workflows. A form can create a CRM record. An order can generate an invoice. If AI is useful, I use it carefully and explain where it can fail. I have worked in healthcare, insurance, legal services, pharmacy and retail. Each industry has its own rules about data, money and customer records. I learn those rules before I start building. menos -

As a System Integrator specializing in Voice AI, I build production-ready systems for clients far beyond Upwork, including agencies, service businesses and founders worldwide. If you’ve moved past the 'cool demo' phase and need a Voice AI system that truly scales, I am the technical bridge you’ve been looking for. My approach is simple: I listen first. The technology (Vapi, Retell, ElevenLabs, N8N) is just the engine. What truly matters is your business goal... more leads, fewer missed calls, higher conversions, smoother operations. I treat every project not just as a job, but as a true partnership. You deserve clarity, reliability, and predictable outcomes. We start by ensuring we’re always aligned on expectations and direction. From there, I dive deep into your workflow and CRM to identify bottlenecks, designing a system that not only delivers measurable results but also sounds natural. 👇 Why I'm the Right Choice for Your Team ◾️ I speak your Language (and Your CRM's): I work closely with platforms like GoHighLevel, so I deeply understand the day-to-day needs of agencies and small businesses. I know exactly what needs to happen to move a lead from the AI call right into your pipeline. ◾️ The System Has to Work: My background is in systems integration. That means I don't just set up the voice AI... I handle all the messy back-end stuff (the API calls, conditions and logic) and make sure everything is talking to your CRM perfectly. No more data silos. Just a synchronized system. ◾️ Speed for Success: I can build and deploy the initial version of your system fast. This is key, because the real work starts when the system is live. I use that real-world feedback to quickly make the improvements that matter, getting you to a truly reliable, production-ready solution sooner. ◾️You Are the Expert, I Am the Guide: You know your customers best. I know the technology best. You bring the insight, I bring the systems. Together, we choose the right tools… whether that’s Retell AI, GHL’s native Voice AI, or another stack, based on what truly serves your calls, your workflow, and your budget. menos -
