Top freelance Oracle SQL developers available to hire
As an expert Software Engineer, I specialize in creating efficient and robust solutions. My expertise extends to advanced web scraping, including handling JavaScript-heavy websites while avoiding reCAPTCHA and IP blocking. With a focus on delivering data in formats like CSV, Excel, and Word, I also offer data cleanup services and database management using MySQL, PostgreSQL, and MongoDB. I take pride in building responsive websites, ensuring they are fluid across all screen sizes. With flexible working hours, I am dedicated to meeting the needs of my clients and ensuring their satisfaction.
As a software developer with 8 years of experience, I am captivated by programming paradigms and the best practices for designing and implementing software architectures.
**I'm happy to offer a 10-minute free session to look at your current work if any exist. This will help us see if I can solve your problem before you pay for a session. This way, I'll better understand what you need and can help you more effectively.**
Let's collaborate to create impactful solutions.
Software Developer with over 6 years of experience specializing in back-end engineering. Proven ability to design and build resilient, scalable micro-services using Java, Spring Framework, and cloud-native technologies. Consistently delivers high-performance software that enhances user experience and drives operational efficiency. Open to new challenges in Software Engineering roles.
I define the architecture. For 21 years, I've been the person CTOs and lead developers call when systems fail under load, migrations are at risk or AI integration needs to work right the first time.
With expertise in .NET, Python, Blazor, ASP.NET Core, SQL and agentic AI architecture (LLMs, reasoning engines, Semantic Kernel, LangGraph, tool-calling agents), I design systems where performance, reliability, and intelligent automation aren't optional—they're the baseline.
I deliver AI in production, not prototypes. I’ve architected and deployed AI-powered systems across financial platforms, education and exam automation, and real estate market intelligence, including enterprise-grade solutions for organizations such as The New York Times, Project Management Institute (PMI), Walmart, Merit Wealth, Namfus and BlueberryCMS.

**Here's where I'm most useful to you:**
- **The AI Integration Trap** — You've been asked to add AI to your existing .NET system but don't know whether to use *Semantic Kernel*, raw OpenAI APIs, or a Python sidecar. I've made that decision dozens of times. I'll make it faster and safer for you.
- **The Blazor Bottleneck** — Your Blazor app is slow, state management is tangled, and you're unsure if you chose *Server or WASM* incorrectly. I can diagnose what went wrong and map a clean path forward — often in a single session.
- **The Legacy Modernization Cliff** — You have a 10-year-old .NET system that needs AI or modern tooling but wasn't designed for it. I specialize in *incremental refactoring paths* that don't require a full rewrite and don't break what's already working.

**What I Do Best:**
- **Software Architecture & System Design** — scalable, maintainable systems from greenfield to enterprise
- **AI Agent Development** — production-grade agents with Semantic Kernel, LangGraph & AutoGen — *not demos*
- **Blazor & ASP.NET Core** — Server, WASM, hybrid — full-cycle development and performance tuning
- **Python & AI Automation** — RAG pipelines, workflow automation, voice AI, LLM integrations, chatbots
- **Legacy .NET Modernization** — refactoring strategy, migration paths, incremental upgrades
- **Architecture Audits** — identifying structural risk before it becomes a production incident, not after
- **Debugging Complex Systems** — when the stack trace doesn't tell the whole story
**If any of this sounds like your current situation — DM me. I respond to every message.**
My recent freelance work has involved Development and programming (Web Development, Oracle Form Builder, Oracle Report Builder, PLSQL, Enterprise Services, Open Sources). I worked on various website using a MySQL and Oracle database,
I love to work with both, they are good for different purposes. I've built several APIs so other website/application may interact with it. I know about responsive design, I like when the website I design can be easily scaled down to iPad or iPhone size since more and more user uses mobile devices nowadays! • Wordpress, Magento, Joomla • Codeignitor, YII, Zend • - ActionScript, Javascript, PHP, AJAX, jQuery • Bootstrap, jQuery, Prototype
I understand how working with freelancers can be frustrating mainly because they can be unreachable and you just don't know if they are a good fit.
