Drowning in legacy .NET modernization, broken LLM pipelines, RAG accuracy issues, or an AI SaaS architecture that can't scale? I build and ship production-ready AI systems, full-stack platforms, and LLM integrations that actually work in the real world. Top Rated Plus, 100% Job Success, 4,830+ hrs, $200K+ earned, 30 five-star reviews, 3x to 10x performance gains delivered. Most clients come to me tired of one of these: • An AI chatbot that makes things up because it isn't grounded in their real data • Hours lost every week to manual work and reporting a machine should handle • A legacy .NET app that's expensive to run and too risky to touch • A great Figma design still sitting unbuilt, or coded badly by someone else • A database and app that crawl as data and traffic grow • AI that looked great in a demo but solves nothing in production I've fixed every one of these, more than once. Here's how I'd help you. 1) AI chatbots, agents & RAG Chatbots grounded on your own data using RAG, LangChain, and vector databases (Pinecone, pgvector), so they answer from your content, not their imagination. GPT-4, Claude, Gemini, with tool use and memory. For your website, Shopify, or WordPress. An AI LMS I built answers in under 200ms. 2) AI automation & Power BI dashboards Workflows that handle the busywork: lead handling, outreach, data, and reporting, built in n8n, Zapier, or Power Automate, plus live Power BI dashboards for your KPIs. A B2B platform I built sends 500+ outreach sequences a day using GPT-4, Playwright, and Celery. 3) Legacy .NET modernization & Azure migration .NET Framework to .NET Core, onto Azure, with documented cost and performance gains. 10+ legacy apps migrated, no scary big bang rewrite. Backends in ASP.NET Core and FastAPI, 100+ APIs, CQRS, DDD, event driven microservices, clean architecture. 4) Figma to React & Next.js Pixel perfect, fully responsive frontends in React 18 and Next.js, hand coded with TypeScript and Tailwind, cross browser tested. Also Angular and Blazor, with real time features via SignalR and WebRTC. 5) Database & query optimization Slow queries fixed with execution plan analysis and proven before/after benchmarks across MySQL, MongoDB, PostgreSQL, and SQL Server. Indexing, query rewrites, schema review, and Redis caching where it helps. 6) Slow app made fast I profile the real bottleneck, queries, caching, code, or architecture, then fix it for measurable 3x to 10x gains across .NET, React, and Node.js. Integrations are a core strength, 50+ delivered: SAP, Microsoft Dynamics, NetSuite, Odoo, QuickBooks, SPS Commerce, EDI (X12, EDIFACT), UPS, FedEx, USPS, Interactive Brokers, Fidelity, Schwab, Shopify, Stripe. Proof at scale: a multi tenant SaaS analytics platform processing millions of data points daily on Azure, and a logistics system handling 10,000+ shipments a day. Cloud and DevOps: Azure App Services, Service Bus, Functions, Kubernetes, CI/CD via Azure DevOps. Why clients stay and come back: • Plain language updates, so you always know status, risk, and what is next • I solve the business problem, not just the ticket • Production ready from day one: documented APIs, parameterised queries, typed frontends, CI/CD, no rework • UK based, responsive across US and European business hours Need an AI chatbot, automation, a .NET rebuild, a Figma to React build, database tuning, or a slow app made fast? Send me the brief and I will tell you exactly how I would tackle it. Available for long term contracts and focused sprints.

I build Apple Watch app, watchOS, and Swift-based mobile products for health, fitness, wellness, healthcare, biometric tracking, and wearable technology companies that need a stable native iOS experience, not just a basic mobile screen. If you need an Apple Watch app for an existing iOS app, a new watchOS product from scratch, or an iOS watch app connected to HealthKit, wearable data, haptics, activity tracking, workout flows, or real-time user feedback, I can help you design, build, and ship it with a clean native architecture. I specialize in Apple Watch app development, watchOS development, Swift development, iOS Development, and Mobile App Development for products where reliability, performance, and user experience matter. My work is focused on native iOS, Apple Watch Application development, watchOS, Swift, SwiftUI, WatchKit, HealthKit, UIKit, Apple Xcode, iOS SDK, Firebase, API Integration, In-App Purchases, and Clean Architecture. For Apple Watch app projects, I can help with: • Apple Watch app development from scratch • watchOS app development for an existing iOS app • iOS watch app architecture and implementation • Swift and SwiftUI development • WatchKit-based Apple Watch Application features • HealthKit integration and HealthKit SwiftUI flows • health, fitness, sleep, activity, and wellness tracking • haptics, notifications, session tracking, and real-time user feedback • wearable integration and smart watch product logic • Firebase, API Integration, data sync, and backend-connected mobile features • App Store-ready iOS and watchOS builds I have 8+ years of experience in native Mobile App Development, including Swift, iOS, iOS Development, Kotlin, Firebase, API Integration, and healthcare/wellness products. I do not approach Apple Watch app development as a simple add-on screen. A good Apple Watch app needs fast interactions, clear watchOS UX, stable background behavior, thoughtful HealthKit integration, reliable sync with the iOS app, and clean Swift architecture. Relevant work includes BlueRoom, an award-winning XR training platform and Garmin Health Awards 2023 winner. BlueRoom used wearable integration, biometric tracking, real-time physiological monitoring, stress response tracking, performance analytics, and real-time data synchronization. While this was not an Apple Watch-only product, the experience is highly relevant to Apple Watch app, smart watch, wearable, biometric, and HealthKit-style products that depend on accurate real-time user data. Another relevant project is MedNAIS, a native healthcare platform for hospitals, labs, and clinics. It included smartphone, tablet, and smartwatch workflows, SOP management, hands-free guidance, roles, permissions, workflows, KPI dashboards, and healthcare team productivity tools. This experience is directly useful for Apple Watch app and watchOS products in healthcare, where smartwatch interactions, iOS watch app flows, and wearable use cases need to be simple, reliable, and useful in real working environments. I also worked on Go Polar, a native Swift iOS wellness app for cold plunge and sauna tracking. The app includes session workflow tracking, custom UI, goal-based time and temperature logic, stats, activity sync, sound controls, and haptics. This is relevant for Apple Watch app, watchOS, HealthKit, health app development, fitness app development, wellness tracking, and wearable product experiences where users need fast, clear, and consistent tracking. If you are building an Apple Watch app, improving a watchOS app, adding an iOS watch app to your current product, integrating HealthKit, building HealthKit SwiftUI screens, or creating a wearable / smart watch experience around health, fitness, sleep, activity, or healthcare workflows, I can help you turn the idea into a stable native product. My focus is Apple Watch app development, watchOS development, Swift development, SwiftUI, WatchKit, HealthKit, iOS Development, Mobile App Development, Apple Watch Application features, API Integration, Firebase, In-App Purchases, Mobile App Design, App Development, and Clean Architecture. I can join at any stage: app consultation, technical planning, Apple Watch app architecture, watchOS feature development, Swift code implementation, iOS watch app integration, HealthKit integration, wearable data sync, MVP development, existing app improvement, bug fixing, or App Store preparation. If your product needs an Apple Watch app that works smoothly with your iOS app, a watchOS experience that feels native, or a Swift-based health, fitness, wellness, or healthcare mobile app with wearable logic, I can help you build it properly. 📩 READY TO START ASAP
