Project details
‼️PLEASE MESSAGE ME BEFORE PURCHASING‼️
Every BLE/IoT device behaves a little differently, tell me which device and platform you're working with so I can confirm this is a fit before you pay for it.
Your BLE device drops connection the moment the app goes to background or pairing works fine in testing, but fails constantly for real users out in the world. These issues are almost always about how iOS and Android handle background processes and power management, not about the Bluetooth chip itself - which is why generic app developers without BLE-specific experience tend to get stuck here.
I implement connectivity that's built for the platform's actual constraints: proper background-mode handling, reconnection logic that recovers automatically instead of leaving the user stuck, and the specific iOS/Android permission and power-management setup that BLE reliability depends on. I've shipped this for parking systems, access-control hardware, and field devices that had to work outside Wi-Fi range - so the device stays connected in real conditions, not just on your desk during a demo.

Technical Discovery Services for Mobile IoT Platform
Vitalii provided excellent technical discovery services for our mobile IoT platform. He brought genuine technical depth, understood the problem quickly, and delivered a clear, well-considered assessment that set us up well for the next phase. Communication was responsive and professional throughout. Highly recommended, and I'd happily work with him again.

.NET MAUI Developer for Desktop App (Windows & MacCatalyst)
We had an excellent experience working with DevsX. Their team provided deep technical expertise in addressing issues related to our defect code signing certificate and guided us seamlessly toward transitioning to Azure code signing. Their knowledge in this area was both thorough and practical, helping us move forward with confidence.
In addition, DevsX brought valuable .NET MAUI expertise to our desktop application, offering clear insights and effective solutions that improved both development efficiency and overall app performance.
What truly stood out was their proactive and solution-oriented approach. They anticipated challenges, communicated clearly at every step, and were consistently responsive to our needs. Their professionalism and top-notch communication made collaboration smooth and highly productive.
We highly recommend DevsX to any team looking for reliable, knowledgeable, and forward-thinking technical partners.

📅 FREE CONSULTATION - WHAT I COVER
🔹 Your product goal, users and constraints - what you're actually trying to achieve
🔹 The technical problem you're stuck on, and how I'd approach it
🔹 Architecture and stack: what fits your case, and what I'd avoid
🔹 A realistic scope, timeline and cost range
🔹 What I'd build or fix first - and what can wait
You leave with a plan you can act on, whether or not you work with me.
🎯 WHERE PROJECTS USUALLY START
💡 You have an idea, not a spec
A short discovery to pin down the business goal, users and constraints - then scope, architecture and an MVP roadmap. You validate the idea before spending months on features nobody asked for.
🔧 You have an app that became a problem
Inherited codebase, original developer gone, bugs that keep returning, releases that keep slipping. I diagnose architecture, integrations and release process, then stabilize first and extend second - with a written list of risks and priorities before touching anything.
📡 You have hardware, and the app is the hard part
A BLE device that drops connection when the app goes to background. GPS tracking that stops when the OS decides to save battery. Offline data that won't reconcile when the signal returns. Or a store rejection over background location and Bluetooth permission declarations. I've shipped parking and access systems, IoT device control, and field inspection tools that had to work outside Wi-Fi range.
🔄 You have a legacy product to modernize
Xamarin, WPF or an aging .NET codebase. Phased migration to .NET MAUI, or a rebuild in Flutter - preserving the business logic and APIs that still work. I've delivered both, so I can tell you which one your situation actually needs.
🤝 You need someone to own the mobile side long term
Ongoing development, new features, OS updates, store releases, and the unglamorous reliability work that keeps an app alive.
⚙️ WHAT GETS DELIVERED
Mobile is the core, but products need more than an app. I cover the backend, APIs, integrations and release pipeline around it, and bring in design, QA and DevOps from my team when a project needs them - one point of contact instead of coordinating four specialists.
📱 Mobile - Flutter, Dart, Swift, Kotlin, .NET MAUI, Xamarin, native iOS & Android
🗄 Backend - .NET, C#, Node.js, Firebase, PostgreSQL, AWS, REST APIs
🔌 Device & integrations - BLE, NFC, GPS, maps, offline sync, background modes, payments, authentication, analytics, push, AI & LLM APIs
🚀 Release - CI/CD, App Store & Google Play, permissions and privacy declarations
🎨 Design & QA - UI/UX, Figma, design systems, manual and automated testing
🌍 INDUSTRIES
Healthcare & medical data · Parking & access control · Fleet & logistics · Fintech & payments · Ecommerce & retail · CRM & enterprise platforms · Education & e-learning · Fitness & wellness · IoT & connected devices · Agritech · Real Estate · Field inspection & asset management · Veterinary · Travel · Marketplaces
✅ TWO WAYS TO START
📅 Book the free consultation
30-60 minutes on a call. We go through your product, the problem and the options and you leave with a plan - whether or not we work together.
📩 Already have an app with problems?
Send me the repository or store link and tell me what's bothering you. Within 48 hours you get a written assessment: top risks ranked, what will block your next release, and whether I'd fix, rebuild or freeze. You keep the document - no obligation.
Either way, you get something useful before spending anything.
