I’ve been building software for over 35 years, and if there’s one thing I’ve learned, it’s this: great code isn’t enough. What matters is creating apps that actually work for people — apps that save time, make life easier, and feel effortless to use. That’s where I come in. I have experience building web, mobile, and Windows apps, from idea through finished product. I’ve worked with C#, C++, PHP, Python, Java, JavaScript, Swift, Kotlin, HTML5, CSS3, Angular, React, ASP.NET, Blazor, Xamarin, MAUI, Uno Platform, React Native, WPF, UWP, Node.js, and more. I’m comfortable working across different platforms, tech stacks, and project types to help turn ideas into working software. What I Bring to the Table - I have 4+ years of experience adding AI features to apps using Azure OpenAI, OpenAI, Anthropic, Fireworks, Hugging Face, OpenRouter, and xAI. I work with custom agents, orchestration, tool harnesses, Text-to-Speech, Speech-to-Text, text-to-image, text-to-video, chat, and other AI features that help businesses automate tasks, improve support, and make smarter decisions. I also use AI development tools like GitHub Copilot, Claude Code, Codex, OpenCode, Grok Build, Warp.dev, Kilo Code, and Cursor AI to work efficiently and choose the right tool for each project. - AI quality & evaluation experience: I’ve reviewed and evaluated large volumes of AI-generated text and video content, identifying inaccuracies, hallucinations, bias, and guideline violations, and providing structured feedback to improve output quality and consistency. - Prompt and validation optimization: I improve AI reliability by refining prompts, validation logic, skills, and review workflows, reducing rework and making AI outputs more dependable in real-world applications. - Testing that catches what others miss: Selenium, Postman, Appium, NUnit, xUnit, MSTest, Cypress, XCUITest, JMeter — I’ve set up both unit and UI automation across multiple platforms. - Databases that scale: MS SQL, PostgreSQL, MySQL, SQLite, DynamoDB, MongoDB, Oracle. I design, optimize, and keep them running fast. - I have experience with Azure, AWS, Google Cloud, and Oracle Cloud, including building and maintaining deployments with Azure DevOps, TeamCity, GitHub, AWS Lambda, Docker containers, Kubernetes, and integrated services across multiple providers. - Integrations that “just work”: From QuickBooks Online, Twilio, Dynamics, AI Providers, UPS/FedEx, merchant gateways, logistics systems, IoT, production scanners, Logistics, IOT, veterinary systems, and even aircraft engine data — I’ve connected it all. Real performance wins: I’ve taken processes from 39 hours down to 2, 30+ minutes down to 2–3, 14 hours down to 20 minutes, and others from days to mere minutes. Optimizing systems is one of my favorite challenges. The Projects I’ve Loved Most: - LMS mobile apps for learning on the go - Sports stats tracking apps for basketball, baseball, soccer, and football - Enterprise systems for Associations, MLM, manufacturing and more - QA testing software that helps teams automate and catch bugs early - App store setup and deployment — getting apps live on iOS and Android without the headaches - Mobile scanning apps for warehouses and delivery teams - Restaurant and mail-order systems - Vet apps across multiple platforms - Web portals for clients - Production line integrations that track, scan, and sync in real-time And through it all, I’ve kept one promise: clear communication and transparency. You’ll always know where your project stands, what’s been done, and what’s next. Whether you need a cross-platform app, a cloud + AI solution, or a system overhaul that saves serious time, I can help. Let’s build something that works better than you imagined.
