I design websites in Figma and build them in WordPress, Shopify and Webflow. Most of my work is around business website redesigns, CMS builds and ecommerce websites that need better structure, stronger UI/UX and a clean mobile experience. For WordPress projects, I handle the full process from Figma design through development using Elementor, Gutenberg, Bricks, Oxygen or Divi depending on the site. I also work with ACF, WooCommerce, forms, migrations, technical SEO and Core Web Vitals when the project needs them. For Shopify, I work on store design, theme customization, Liquid/front-end changes, product and collection structure, PDPs, cart flows, responsive design and ecommerce UX. I can work with an existing theme or build out a more custom design depending on the scope. For Webflow, I build CMS-driven websites with reusable components and a backend that stays easy to update after handoff. I normally start with the design and structure first. That means wireframes, page flow and Figma before development when the project calls for it. This helps us get the direction right before time is spent building. I also stay involved through responsive testing, QA, performance checks and final handoff. My main areas of work: • Website redesigns and new business websites • Figma UI/UX and developer-ready website design • WordPress design and development • Shopify ecommerce design and development • Webflow CMS websites • Ecommerce PDP, collection and mobile UX improvements • Website migrations and rebuilds • Core Web Vitals and on-page SEO setup I work mainly with ecommerce, healthcare, fitness and wellness, SaaS, professional services and B2B businesses. If you already have a site, send me the link and a little background on what you want to improve. I can usually tell you pretty quickly what I would keep, what I would change and which platform or approach makes the most sense.

⭐ Top 1% AI/ML, Production RAG systems, AI agents, MCP servers, and LLM SaaS products on LangGraph, LangChain, LlamaIndex, n8n, Python, and FastAPI 💰 $20k+ delivered on Upwork 🕒200 hours delivering Software Systems ⭐ Five Star Reviews ✅ 10+ years building AI solutions ✅ 5+ projects delivered for startups and enterprise clients 𝐖𝐇𝐀𝐓 𝐈 𝐁𝐔𝐈𝐋𝐃: 1. Production RAG & Document Intelligence Retrieval-Augmented Generation over your PDFs, contracts, tickets, CRMs and databases. Hybrid search, reranking, citations on every answer, role-based access control, and a scored eval set so quality stays measurable after launch. Pinecone, Weaviate, Qdrant, FAISS, pgvector. My last enterprise RAG cut document search time 70%, retrieval precision up 75%. Your document mix decides retrieval quality more than the model does, so scanned PDFs, tables, and messy exports are where I start. 2. 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭𝐬 & 𝐌𝐮𝐥𝐭𝐢-𝐀𝐠𝐞𝐧𝐭 𝐒𝐲𝐬𝐭𝐞𝐦𝐬: Agentic AI for email triage, document review, compliance checks, lead qualification, and internal ops. Built on LangGraph and CrewAI, wired into your real tools through MCP servers, n8n, and APIs. Human approval sits exactly where mistakes are expensive. Agents run unsupervised only where they have earned it. 3. 𝐕𝐨𝐢𝐜𝐞 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭𝐬: Inbound and outbound voice on LiveKit, Deepgram, ElevenLabs, Retell and Vapi. Interruption handling and endpointing are where the build time goes, not transcription accuracy. My last voice agent automated 80%+ of tier-1 calls at sub-second latency, with handle time down 45%. 4. 𝐎𝐧-𝐏𝐫𝐞𝐦𝐢𝐬𝐞 & 𝐏𝐫𝐢𝐯𝐚𝐭𝐞 𝐋𝐋𝐌 𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭: For data that cannot leave your infrastructure. Self-hosted open-source models, fine-tuning with LoRA and QLoRA, vLLM inference serving, PII handling and audit trails from day one. Built for healthcare, legal and finance teams under HIPAA, GDPR and SOC 2 constraints. 5. 𝐋𝐋𝐌 𝐒𝐚𝐚𝐒 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐬 & 𝐀𝐈 𝐂𝐨𝐩𝐢𝐥𝐨𝐭𝐬: Auth, dashboards, admin panels, backend APIs, database design, deployment and token cost controls. AI inside the tools your team already uses, so answers arrive where people work. An LLM product users can pay for, not a wrapper. 6. 𝐀𝐈 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧 𝐑𝐞𝐬𝐜𝐮𝐞 & 𝐓𝐚𝐤𝐞𝐨𝐯𝐞𝐫: Half-built, abandoned, or AI-generated codebases brought to stable production. I map what is broken before touching anything, then rebuild while your users keep using the product. My most requested work. 7. 𝐋𝐋𝐌𝐎𝐩𝐬 & 𝐄𝐯𝐚𝐥𝐮𝐚𝐭𝐢𝐨𝐧: Golden sets from your real queries, scored on every deploy. Versioned prompts and index snapshots. A trace per answer storing the retrieved chunks, not just the output. LangSmith, Langfuse, Ragas, MLflow. This is what stops a system drifting in month 3. 𝐖𝐇𝐎 𝐓𝐇𝐈𝐒 𝐈𝐒 𝐅𝐎𝐑: Founders shipping their first AI product. Funded teams taking an MVP to real users. Companies whose last AI build cracked and need a rescue, not a restart. 𝐓𝐄𝐂𝐇 𝐒𝐓𝐀𝐂𝐊: LLMs: OpenAI, Anthropic Claude, Gemini, Llama, fine-tuned open models Agents: LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, n8n, MCP RAG: embeddings, hybrid search, reranking, GraphRAG, Pinecone, Weaviate, Qdrant, FAISS, pgvector Backend: Python, FastAPI, REST APIs, React, Next.js Data & Cloud: PostgreSQL, MongoDB, Redis, AWS Bedrock, Azure AI Foundry, GCP Vertex AI Deployment: Docker, Kubernetes, CI/CD, MLflow, LangSmith, vLLM I currently lead an AI engineering team in a full-time role, which is where most of my hands-on RAG/agent architecture experience comes from. I combine AI/ML engineering with full stack development (frontend, backend, API integration, cloud deployment) to build AI driven solutions and automation systems that scale.

🏆 Send me your project and I will tell you honestly whether Flutter or React Native fits your Software Development plans better, within minutes. If you need a Flutter Mobile App Developer or React Native Developer who delivers production-ready iOS and Android apps that perform under real user load, scale with your growth, and don't require constant hotfixes after launch, you're in the right place. I'm a Flutter Mobile App Developer and React Native Developer with 6+ years of hands-on Mobile App Development experience. I have shipped 30+ Flutter projects, dozens of React Native apps, and 250+ mobile and web products across 45 countries. Not prototypes. Real apps with real traffic, real edge cases, and real business logic. I don't just write code, I own the outcome and manage the project, so you're never left wondering where things stand. What makes me different Most developers hand off a working build and move on. I stay involved. Whether the job calls for a Flutter Mobile App Developer, a React Native Developer, or native iOS Development and Android App Development in Swift and Kotlin, I design architecture that fits long-term, write code your future team can read, and manage the project so you know what's next and what's at risk. Services As a Flutter Mobile App Developer I build cross-platform App Development for iOS and Android from a single codebase with 60fps performance. As a React Native Developer I build the same reach when your team's stack points toward React Native instead. When a product genuinely needs it, I also handle native iOS Development in Swift and native Android App Development in Kotlin and Java. Either way: custom mobile architecture, backend and API integration (REST, GraphQL, WebSockets, real-time sync), payment gateway integration (Stripe, Apple Pay, Google Pay), legacy app rescue, Mobile App Redesign, CI/CD, and App Store and Google Play deployment. Results Every project I deliver is measured against real outcomes: Up to 60% faster app load times Up to 40% reduction in crash frequency Up to 50% improvement in API reliability 40-60% improvement in overall app performance 30-45% reduction in crash rates after refactoring 5x growth in active users sustained without downtime Recent Projects For a FinTech client, I shipped a Flutter app to iOS and Android from one codebase, handling Apple Pay and Google Pay without diverging logic between platforms. For a Healthcare startup, I rebuilt a legacy iOS app and brought Android to parity within the same release, cutting the usual gap to weeks. By Industry As a Flutter Mobile App Developer and React Native Developer I have worked across a wide range of industries with real production apps behind each one. SaaS is my primary focus with 35+ platforms shipped, from early MVPs to enterprise systems with subscription management. In Healthcare I have delivered 25+ mobile projects with HIPAA compliance and data privacy in mind. FinTech accounts for 25+ apps including secure payment systems. Enterprise tools account for 20+ projects covering internal automation. EdTech accounts for 15+ builds with media streaming and offline modes. Marketplace and eCommerce accounts for 15+ apps covering catalog management and checkout. Tech Stack Flutter, Dart, Bloc, Provider, Riverpod, React Native, TypeScript, JavaScript, Redux, Kotlin, Swift, Java, Git, REST, GraphQL, WebSockets, Firebase, Supabase, Stripe, AWS, GCP, Docker, CI/CD, App Store, Google Play How I work Discovery: defining goals, user journeys, and technical constraints before writing code, including whether Flutter, React Native, or native Swift/Kotlin is right for your team. Architecture: state management, system logic, and backend integration built for scale. Development: clean code, pixel-perfect Mobile App Design across screen sizes, seamless API connectivity. Mobile App Testing: validation of performance under load, crash rates, and cross-device compatibility on real smartphone hardware, not just simulators. Launch: structured App Store and Google Play deployment with post-launch monitoring. I also handle project management myself, so there's no handoff gap between the person writing the code and the person tracking the timeline. What you get A Flutter Mobile App Developer and React Native Developer who takes full ownership of architecture, code stability, and delivery Clear milestone breakdowns, no surprise delays Clean documented code your team can work with Active project management from first sprint to release Post-launch support, not a handoff and goodbye Ready to work with a Flutter Mobile App Developer or React Native Developer who builds solutions that scale and grow with your users? Send me a message. P.S. Tired of developers who overpromise and underdeliver? Send me your project for an honest conversation about what it actually takes to build it right.

I enjoy building products that solve a real problem, especially when AI can make the experience smarter, simpler, or more useful. For the past 10+ years, I have been building digital products across AI, web, mobile, backend and cloud. I have worked on everything from early-stage ideas and MVPs to established applications that need new features, better performance, or a completely new direction. These days, a big part of my work is bringing AI into real products, not just adding a chatbot, but figuring out where intelligence can actually improve the product or business. WHAT I CAN HELP YOU BUILD • AI products & features
 AI agents, assistants, chatbots, LLM-powered applications, recommendation systems, document intelligence, OCR, NLP, computer vision and custom AI functionality. • Automation that saves time
 I build workflows that connect the tools you already use and take repetitive work off your team’s plate. This includes n8n, Make, Zapier, APIs and webhooks, with AI added where it makes sense. • Web & SaaS applications
 MVPs, SaaS platforms, dashboards, customer portals and custom business applications using React, Next.js, Vue, Node.js, Nest.js, Django and Laravel. • iOS & Android applications
 Native and cross-platform apps using Swift, SwiftUI, Kotlin, Flutter and React Native, including AI features, real-time functionality, payments, subscriptions, notifications and location services. Behind all of this, I am comfortable with the APIs, databases, integrations and cloud infrastructure that keep the product running reliably. HOW I APPROACH A PROJECT I do not believe every problem needs AI, and I do not believe every product needs a complicated architecture. I like to understand what you are trying to achieve first. From there, I can help work out what should be built, where AI or automation is actually useful, and how to keep the product reliable as it grows. If you already have a clear specification, great. If you have a Figma design, an existing application, or simply an idea that you have not fully figured out yet, that is fine too. TECHNOLGIES I WORK WITH • AI / ML: OpenAI | Claude | Llama | ElevenLabs | TensorFlow | PyTorch | Scikit-learn | Tesseract • Web / Backend: React | Next.js | Vue | Node.js | Nest.js | Express | Python | Django | Laravel • Mobile: Swift | SwiftUI | Kotlin | Flutter | React Native | Ionic • Data / Infrastructure: PostgreSQL | MongoDB | MySQL | Firebase | AWS | GCP | Azure | Docker I have worked on products across fintech, healthcare, e-commerce, real estate, travel, education, social platforms, streaming, booking, on-demand services and AI-focused products. If you are building something and need someone who can understand the idea, think through the technical side, and actually build it, send me an invite or message. Let’s connect and see what we can build.
