📍 React Native development for production mobile apps 📍 Full stack engineering for complex backend systems 📍 AI Agent Development for automation and intelligent workflows For more than 11 years, I’ve been working in mobile app development and full stack development, delivering scalable web platforms, high-performance mobile apps, and modern AI-driven systems. This combination allows me to build products end-to-end, from mobile UI to backend architecture and AI logic. 📱 Mobile App Development & React Native Expertise As a React Native developer, I’ve built and scaled mobile applications used in fintech, real estate, healthcare, marketplaces, and social platforms. My mobile app development experience includes: - Cross-platform iOS and Android apps - Complex user roles and permissions - Real-time features (chat, live updates, tracking) - High-load backend integrations - Clean architecture designed for long-term growth One of my key projects Breeze, a real estate mobile platform was developed end-to-end as a full stack developer and later raised $3M+ in investments. That experience strongly shaped how I approach architecture, scalability, and product quality. 🤖 AI Agent Development & Automation In parallel with product engineering, I focus heavily on AI Agent Development. As an AI Agent Developer and AI Automation Expert, I design systems that go far beyond simple chatbots. I build: - AI agents with planner-executor architecture - Multi-agent systems with task orchestration - AI chatbots connected to business data - AI automation pipelines for operations, research, and analytics - RAG systems using embeddings and vector databases These AI agents are designed to interact with real systems, APIs, CRMs, databases, internal tools, and operate as part of a real product ecosystem. My goal is always the same: turn AI from an experiment into a reliable, controllable product component. 🔗 Where AI meets Full Stack Development What makes my approach different is the combination of: AI Developer + Full Stack Developer + Mobile App Developer This means: - AI agents integrated into web platforms - Mobile apps powered by AI logic - Backend services managing agent execution - Dashboards for monitoring and control - Secure and scalable infrastructure Instead of isolated AI tools, clients get complete AI-powered products. 💡Clients usually come to me when they need: - A senior engineer who understands product logic - A CTO-level partner, not just a coder - Clean architecture from day one - Systems prepared for growth, investment, and scale That’s why many clients stay long-term and treat me as a technical partner, not a temporary freelancer.

If your project needs more than someone who writes code to spec — if you need someone who can architect the solution, own the delivery, and still be there for support six months later — that's the role I take on. WHAT I BUILD ──────────────────────── ✦ SaaS Platforms — multi-tenant, subscription-based .NET Core / Azure applications built to scale from a handful of users to enterprise volume ✦ Healthcare Systems — HIPAA-aware EHR/EMR platforms, HL7/FHIR integrations, and clinical workflow tools built to compliance standards ✦ Fintech & Payments — secure transaction processing, Stripe/PayPal integrations, reporting and reconciliation systems, PCI-conscious architecture ✦ E-Commerce Platforms — custom storefronts, order/inventory management, and integrations with payment gateways, CRMs, and ERPs ✦ Real Estate & Property Management Systems — listing platforms, tenant/lease management tools, and workflow automation for property teams ✦ AI-Powered Features — OpenAI/LLM integrations, intelligent document processing, and AI-assisted workflows added to existing .NET applications ✦ Legacy Modernization — turning outdated ASP.NET/VB.NET systems into maintainable, cloud-ready .NET 8 platforms without breaking what already works TECH STACK ──────────────────────── + Backend: C# · .NET 8 / .NET Core · ASP.NET Core · ASP.NET MVC · Web API · Entity Framework Core · LINQ · Blazor · SignalR · Microservices · REST & SOAP APIs + Frontend: Angular · React · TypeScript · JavaScript · HTML5 · CSS3 · Blazor UI + Cloud & DevOps: Microsoft Azure (App Services, Functions, AKS, Service Bus, Key Vault, Azure SQL) · AWS (EC2, Lambda, RDS, S3) · Azure DevOps · GitHub Actions · CI/CD · Docker · Kubernetes · Infrastructure as Code + Databases: SQL Server · PostgreSQL · Cosmos DB · MongoDB · Stored Procedures & Query Optimization for high-volume systems + Integrations: Stripe · PayPal · Twilio · SendGrid · OAuth 2.0 · HL7 · FHIR · CRM/ERP integrations HOW I WORK ──────────────────────── I stay involved from architecture through deployment — writing clean, documented, production-ready code, and communicating progress clearly at every step. I manage scope, timelines, and stakeholder expectations as carefully as I manage the codebase itself. Depending on what your project needs, I can work as a hands-on senior engineer, a solution architect, or a long-term technical lead. I'll tell you honestly, early, if I'm the right fit for what you're building. Send me your project scope and I'll respond within a few hours.

I help enterprise and operations-heavy teams turn messy business processes into reliable systems. I’ve spent 15+ years building and leading production software systems: .NET platforms, Azure infrastructure, SQL databases, APIs, internal tools, reporting workflows, and business-critical applications. That background lets me bridge the gap between AI experimentation and software that a real business can actually depend on. I work best where software needs to connect with real operations - documents, databases, CRMs, spreadsheets, internal portals, legacy systems, approval workflows, reporting processes, and human review steps. I use Claude Code and OpenAI Codex as part of my daily engineering workflow: reviewing codebases, planning features, accelerating development, testing ideas, refactoring safely, and turning business requirements into working software faster. My value is knowing how to apply AI inside real production environments where architecture, security, data quality, maintainability, and auditability matter. I can help with: 🔧 Process Engineering - mapping workflows, finding automation opportunities, and designing safer AI-assisted processes 🤖 AI Automation - document processing, internal tools, reporting automation, CRM/data-entry support, and review queues 🧠 AI/LLM Development - assistants, RAG/search, structured outputs, guardrails, evaluations, and human-in-the-loop workflows 🏗️ .NET / Azure / SQL Integration - connecting AI into existing enterprise systems without creating fragile side projects 📐 Fractional CTO / Technical Lead Support - architecture, roadmap planning, risk review, estimates, and execution strategy A typical first step is a short discovery and workflow review. From there, I give you a prioritized plan: what can be automated, what should stay human-reviewed, where the risks are, what it will cost, and what can be shipped first. Message me with your current process, stack, pain point, and deadline. I’ll help you turn the time-sink into a working system.
