I build mobile apps, websites, and web platforms that people actually use — and pay for. Over the past 3 years, I've shipped 15+ products from scratch, generated over $1M in combined revenue, and reached 2M+ downloads across the App Store and Google Play. One of my own apps (GlamAI, an AI-powered beauty app) hit ~$800K in revenue and was acquired within 15 months of launch. I run Viral Tech, a solo dev studio based in Montreal. I work directly with founders and businesses to take ideas from concept to live product — fast. I recently built and shipped a full AI-powered iOS app in 4 days, and built a complete business website from a single prompt using Next.js and deployed it the same day. What I build: — Mobile apps (Flutter, Swift/SwiftUI — iOS & Android) — Websites and landing pages (Next.js, React, Tailwind) — Web apps and SaaS platforms (full-stack with auth, payments, dashboards) — AI-powered products (Claude API, OpenAI integration) What I'm best at: — MVPs and v1 launches for startups — AI-powered apps and websites — Full-stack builds (frontend + backend + deployment) — SaaS and subscription-based products — Navigating App Store review rejections I handle design, development, backend, and deployment. No handoffs, no miscommunication, one person who owns the entire build.

I build custom web platforms that replace off-the-shelf tools — CRMs, ERPs, SaaS products, eCommerce marketplaces, and mobile apps. Based in New Jersey, sole engineer on every project I ship. Recent work: replaced HubSpot entirely for a national manufacturer with a custom CRM (live 10+ months), built a full ERP billing platform in production, and developed a multi-vendor eCommerce marketplace currently in beta. What I build: Custom CRM & ERP systems eCommerce platforms & marketplaces SaaS products (schema to deployment) REST APIs & backend systems Mobile apps (iOS & Android — React Native) Stack: Next.js · NestJS · TypeScript · PostgreSQL · MongoDB · React Native · Stripe · AWS S3 Message me with what you're building. I'll tell you if I can help and how.

Hi I am new to Upwork this month - but I don't just build apps — I build AI-powered products that scale. This isn't a typical developer profile. I'm Ben Hogan, one of the UK's most experienced mobile app and SaaS developers with 17+ years shipping real products at real scale. I started building apps in 2008, gained national recognition on BBC TV, and have spent the years since building products that dominate App Store charts, power thousands of businesses, and now lead the AI revolution in mobile and web development. WHAT MAKES ME DIFFERENT Most developers build to spec — I build to succeed. I've been on both sides of the table: as a founder who's built and scaled my own products, and as the developer trusted by major brands to deliver theirs. That dual perspective means I ask the questions most developers don't, challenge decisions that will cost you later, and bring genuine product thinking to every engagement. I founded Cynfia — my own production AI platform built specifically for business owners — and run SaaS products used by over 4,000 venues across the UK. I work closely with the teams at Klaviyo and Klevu, relationships built over 18 months of deep platform work that give me a level of access and insight most developers never reach. I use my own custom AI-assisted development environment built on a proven proprietary stack — which means I deliver faster and smarter than a standard developer, without cutting corners on quality. WHAT I BUILD — AI-native mobile apps — Flutter, iOS, Android, cross-platform — SaaS platforms — multi-tenant, RBAC, Supabase, production-ready — Headless web platforms — React, Next.js, Vite, Tailwind — superfast and built to rank — Headless Shopify storefronts — custom, fast, conversion-focused — AI integrations — Claude, GPT-4, Gemini, RAG pipelines, workflow automation — Operational dashboards — fleet management, field service, hospitality, legal, charity — Ecommerce strategy and builds — I led a UK PLC digital strategy for 18 months, growing their average monthly revenue from £1.2M to £1.8M BRANDS AND PROJECTS I'VE WORKED WITH Cakebox · Firebox · Funny-Gifts · Walkers · IKEA · Strava · Harrods · Slendertone · Hollywood Bowl · — plus hundreds of startups and founders across the UK and globally CREDENTIALS THAT MATTER — 300M+ app downloads across 147 countries — #1 App Store rankings in multiple categories — Won Best Fitness App 2015 — knocked Nike off the top spot — BBC TV featured — introduced mobile apps to Richard Branson and Richard Reed on national television — Founder of Cynfia — production AI platform for business owners — SaaS products serving 4,000+ UK venues — Built a custom smartwatch for Will I AM — Got UK PLC from £1.2M to £1.8M average monthly revenue over 18 months MY TECH STACK Flutter · React · Next.js · Vite · Tailwind CSS · Supabase · TypeScript · Dart · Swift · Kotlin · Laravel · Claude API · GPT-4 · Gemini · RAG · Stripe · Vercel · Firebase · AWS · MongoDB · Sanity · Clerk · Resend HOW I WORK I take on a small number of projects at a time because I give each one proper attention. I communicate clearly, hit my deadlines, and tell you what you need to hear — not what you want to hear. If something in your brief is going to cause problems later, I'll say so upfront. I work with founders and businesses who want a senior technical partner with real commercial instincts — not just a pair of hands pointed at a spec. If that's you — I'd love to hear what you're building. ONE LAST THING My rate reflects 17 years of production experience, a track record of 300M+ downloads, and the ability to bring AI-powered development to your project from day one — not as a buzzword, but as a genuine working capability I've built and proven over three years. You're not hiring a developer. You're hiring someone who has built #1 products, grown brands to millions in monthly revenue, and founded their own AI platform. The right project gets my full attention, my full experience, and results that justify every penny.

5 years building Flutter & React Native apps. 2.9M+ downloads. 5.0/5 on the App Store. That is the kind of work I deliver. I build production-grade Flutter, React Native, and native iOS apps for startups and scale-ups. I have real experience across fintech, Web3, healthcare, and social platforms, and I'm just as comfortable picking up new industries. My work doesn't just ship - it scales. My background: At Hunch, I helped take Goss Chat to Top 25 on the US App Store with 2.9M+ downloads. At Avici Money, I rebuilt a broken Web3Auth and WebAuthn Passkey integration for a live crypto wallet - now holding a 5.0/5 iOS rating. At Unikon.ai, I shipped real-time AI coaching sessions with Agora video and audio. At Ziploan, I led a 3-developer team building a full B2B loan origination platform from scratch.

Published api_state on pub.dev - 160/160 score. What I do particularly well: - Re-architecting legacy codebases into clean, modular Flutter and React Native apps - Building real-time features: chat, video, VoIP, live sessions - Integrating complex auth: biometric, passkey, Web3Auth, DigiLocker KYC - Owning full delivery: architecture to code to CI/CD to App Store release I am currently available and taking on new projects. If you are building something in Flutter, React Native, or native iOS and want a developer who can own it - let's connect.

You have a product vision that's too complex for most developers. Maybe your last hire got stuck. Maybe you've been told it "can't be done." I'm the one who builds it — and I've been doing it for 10+ years for clients like NBC, BBC, CBS, and Rolls-Royce. I'm a 2x CTO and full-stack architect. I don't just code features — I take a concept, architect the system, plan the execution, build across every layer, and ship to production. 40+ products delivered across 10+ countries. Here's what that looks like: BUILT A FULL IOT TRACKING PLATFORM — ALONE — ACROSS 5 PLATFORMS iOS app, Android app, React web portal, Java Spring Boot microservices, Unreal Engine 3D visualization. 3,000 beacons deployed across industrial facilities. 5,000+ workers and 1,000+ spare parts tracked daily. Custom signal-processing algorithms I designed from scratch for environments where BLE signals bounce off metal walls. The CTO of Rolls-Royce Finland wanted to license it for their factory plants. Still running in production 7 years later. REBUILT AN ENTERPRISE MEDIA PLATFORM FOR NBC, BBC, CBS, AND THE TIMES Replaced a browser-based tool with a native macOS application. 15-20x performance improvement. FFMPEG integration, Core ML, hardware-accelerated encoding. The platform is now used every day to tag, search, and transcode terabytes of video for some of the biggest names in media. Promoted from developer to senior developer in 6 months. TOOK A VR STARTUP FROM ZERO TO ACQUISITION OFFERS AS CTO Architected a 4-component ecosystem from a blank canvas: Swift macOS app, Unity VR mobile (iOS/Android), React/Next.js web platform, TypeScript/Firebase backend. Pioneered features no competitor has replicated — ARKit spatial tracking with sub-10ms latency, XR passthrough at 60 FPS. Five years of R&D. Now fielding acquisition offers. CO-FOUNDED A SOFTWARE HOUSE — 15 ENTERPRISE PROJECTS IN 3 YEARS Built and trained a team of 18 developers. Replaced a six-figure German ERP quote with a custom solution: offline-first sync, POS integration, CCTV integration across 7 branches. Launched Egypt's first fresh meat e-commerce platform. Ran two CTO roles simultaneously. WHAT I DO FOR YOU Full-Stack Product Development You bring the idea or the problem. I deliver the product. End to end. React / Next.js / TypeScript on the web. Swift across all 7 Apple platforms. React Native for cross-platform. Node.js / Firebase / Java on the backend. AWS, Docker, CI/CD for infrastructure. R&D & Execution Planning This is where I'm different. I don't just build — I figure out what to build and how. System architecture, technology selection, PRDs, implementation roadmaps, risk analysis. I've done this for VR training simulations, industrial IoT systems, multi-platform consumer apps, and enterprise ERP. You get a concrete plan, not a guess. Technical Consulting & Advisory Architecture reviews. Performance audits. Legacy modernization. Team scaling. I've scaled engineering teams from 2 to 20+, designed modular architectures for distributed teams, and created documentation systems (100+ technical docs, 46 UML diagrams) that make knowledge transfer seamless. MY STACK Web: React, Next.js, TypeScript, JavaScript Mobile: Swift (iOS/macOS/watchOS/tvOS/visionOS), React Native, Flutter Backend: Node.js, Firebase, Java Spring Boot, Python, .NET Infrastructure: AWS, Docker, Kubernetes, CI/CD Specialized: Unity (VR/AR), ARKit, Core ML, BLE/RFID (IoT), Unreal Engine WHY CLIENTS TRUST ME AT THIS RATE - NBC, BBC, CBS, The Times, Rolls-Royce — I've delivered for names that don't tolerate mediocre work - 2x CTO — promoted to CTO at CanterVR in 4 months from Senior Developer - Every system I've built is either still running or was deliberately sunset — nothing I ship breaks and gets abandoned - Engagements that start as 3-month contracts turn into multi-year partnerships - I've shipped across media, manufacturing, VR, e-commerce, logistics, marine tech, and healthcare HOW I WORK - I own the outcome, not just the tasks - Daily progress updates, live demos, zero surprises - If something won't work, I'll tell you before you waste money on it - I move fast but I don't cut corners — production code, not prototype code Tell me what you're building. I'll tell you exactly how I'd make it happen — and if I'm not the right fit, I'll say that too.

Senior Android Engineer (10+ Years) | Kotlin | Jetpack Compose | KMP | Scalable Mobile Apps I help startups and companies build and scale high-performance Android applications used by millions of users. Specializing in Kotlin, Jetpack Compose, Kotlin Multiplatform (KMP), and Clean Architecture, I design apps that are fast, stable, and built for scale. I’ve worked across Fintech, GovTech, E-commerce, and Travel platforms, delivering production-grade mobile systems with strong focus on performance, maintainability, and user experience.

I am an accomplished Mobile Engineering Lead with 17 years of experience in developing high-impact applications. As a pioneering mobile developer since 2009, I have co-founded two successful mobile app startups and led diverse teams in creating apps with over 1 billion downloads. My expertise includes native development for Android and iOS, as well as crafting robust cross-platform solutions using Flutter. I excel in integrating AI tools to streamline development processes and enhance team performance. I provide strategic guidance while fostering an environment for continuous improvement, mentoring engineers, and aligning technical direction with business goals. If you need an expert who can not only build exceptional apps but also elevate your team’s capabilities, let's connect and turn your vision into reality.

If your business has outgrown packaged software, I build what fits — custom, end-to-end solutions designed around your exact processes. Since 2006, I've delivered bespoke software across 8+ countries for clients ranging from global enterprises to funded startups. I currently maintain active support contracts with Vodafone and Philip Morris International, and have built and shipped products in logistics, fintech, agriculture, manufacturing, real estate, maritime, and SaaS. What I bring that most developers don't: — I've sat inside IT departments of large corporations, so I understand how decisions are actually made and what "production-ready" really means. — I've founded multiple software ventures of my own, so I understand the pressure of building something that has to work from day one. — I work across the full stack: mobile (Expo / React Native), web, desktop, backend APIs, cloud infrastructure (Azure, AWS), databases (MSSQL, Supabase, PostgreSQL), and third-party integrations (Stripe, open banking, ERP systems, barcode/IoT, and more). — I own physical iOS, Android, macOS, and Windows devices — every build is tested on real hardware. I work in structured weekly milestones with written updates, clear communication, and no surprises. My clients stay with me long-term because the work is done properly the first time. If you have a project that needs to be built right — not just built fast — I'd like to hear about it.
