I build production AI agents and agentic workflows not prototypes, not experiments.
If you need an AI system that executes multi-step tasks autonomously, routes intelligently across models, maintains session context, and ships to production without hand-holding, this profile is for you.
Clients come here when they have already wasted time with someone learning on their budget and need an engineering partner who has done this end-to-end before.

𝗔𝗜 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 - intelligent process automation that removes human effort from repeatable workflows without sacrificing reliability
The backend engineering, AI integration layer, session management, prompt engineering, and production deployment are all handled in one engagement. You are not coordinating between three contractors.

I built the full custom product, delivering an enterprise Property Platform with AI-Assisted Intelligence engineered with an AI property description generator, intelligent property search, and real-time real estate inventory sync. The system acts as an end-to-end real estate CRM integration that captures advanced buyer behavior analytics across three distinct user roles. By deploying this custom AI software, the business replaced manual content workflows and disconnected tools with a single, scalable ecosystem they can completely operate and extend.

I take long-term engagements seriously and work at 40+ hours per week for dedicated projects. Before writing a line of code I want to understand the business problem not the feature list. The technical decisions made at the start determine how well the system behaves at scale.
If your project has a real deadline, a real user base, or a real budget, I am the right fit. If you are still validating whether AI can solve your problem at all, I will tell you that upfront.

I'm a full-stack .NET developer with 11 years of experience based in Los Angeles. I'm a true full-stack developer, so I can work equally well on both front and back ends. I have experience in building applications from start to end, so I can take care of building almost any project, then supporting it for the long term.
Here are some highlights from my background:
- My tech stack is .NET, .NET Core, C#, SQL, Entity Framework, HTML, CSS, JavaScript, and Angular.
- Experience with Azure and AWS. I'm especially good with Azure. I can setup Azure resources such as App Services, Function Apps, Azure SQL Databases, Storage Accounts, Key Vaults, Azure DevOps source control, deployment pipelines, etc.
- Experience in working on large SaaS applications in healthcare, manufacturing, retail, human resources, and legal industries.
- Experience in developing MVPs from start to end.
- I write clean and understandable code with well defined architecture using best practices for software security.
- Experience in SaaS and multi-tenant applications.
- Great work ethics and honesty. If I don't know something, I'll tell you. If I messed up something, I'll tell you.
My Certifications:
- Microsoft Certified: Azure Developer Associate
- Microsoft Certified: Azure AI Engineer Associate
Also, I have a team of full-stack software developers. Building and supporting an application for a successful startup usually requires more than one developer. Building an application is like building a house. It usually requires a crew to complete. My team can join your project and help with building it, then support and enhance it in the future.

8 years ago, I took on my first ASP.NET developer contract. Since then, I have shipped 35+ projects across defence, renewable energy, fintech, e-commerce, and enterprise SaaS — and I am still the developer clients come back to when the system needs to actually work under pressure.
What I build as an ASP.NET Core developer
My deepest work is in ASP.NET Core back-end architecture. I spent years as the lead ASP.NET developer on a platform that manages thousands of wind and solar energy installations globally — processing massive volumes of real-time data, building microservices on .NET Core and Azure, and making sure the system delivered actionable analytics without costly downtime. That kind of scale teaches you things no tutorial covers.
On another project I built a Loan Origination System in ASP.NET Core that automated the entire loan lifecycle — from lead capture to loan issuance — integrating with HubSpot, external CRMs, and financial APIs on Azure. The client went from manual processing to a fully automated fintech pipeline.
ASP.NET MVC and legacy modernization
Some of my most complex ASP.NET MVC work has been in defence and industrial sectors. I modernized a legacy web platform for a company managing high-uptime naval fleet assets — warships that cannot afford downtime. The ASP.NET MVC rebuild enabled accurate asset tracking, secure document storage, and streamlined access to sensitive operational data. On another engagement I took over a large workplace management SaaS system that a single developer had left behind — no documentation, daily hotfixes, frequent outages. I stabilized the ASP.NET Core back-end, eliminated the performance bottlenecks, and established proper development processes from scratch.
ASP.NET Zero and enterprise acceleration
ASP.NET Zero is my go-to when enterprise clients need multi-tenancy, role-based permissions, and audit logging without spending the first three sprints on boilerplate. I have used it to accelerate delivery on projects in pharma automation, workplace management software, and industrial IoT — cutting setup time significantly and letting the team focus on actual business logic from day one.
Full-stack development across the whole system
Full-stack development for me means owning the entire delivery — ASP.NET Core back-end, Angular or React front-end, Microsoft SQL Server database design, and Azure infrastructure. I built a Shopify fulfillment tool in ASP.NET Core and React that reduced packing mistakes to zero for e-commerce teams — integrating barcode scanning, inventory management, and connections to 8+ shipping providers. I have also delivered a fleet management system in .NET 9 and Angular handling large industrial equipment rental, tracking, and reporting at scale. On the front end I work with Angular, AngularJS, React, TypeScript, JavaScript, and Bootstrap — and I connect them cleanly to ASP.NET back-ends without creating maintenance nightmares six months later.
Back-end engineering that goes deep
Back-end development across 8 years means I have seen what breaks under real load. I optimize Microsoft SQL Server queries, design database schemas that support complex reporting, and build API integration layers connecting ASP.NET systems to CRMs, ERPs, payment gateways, and third-party platforms. I work with Node.js for event-driven services, TypeScript to keep large codebases maintainable, and Python or PHP when projects need scripting layers or data pipelines alongside the core .NET stack. For infrastructure I use Microsoft Azure and Amazon Web Services — CI/CD pipelines, Docker, microservices, the full picture.
Why clients come back
I have worked with clients in Germany, the USA, Australia, the UK, Norway, Denmark, and the Netherlands. The industries range from renewable energy and defence to fintech, e-commerce, and industrial IoT. What stays the same across all of them: I ask the right questions before writing the first line of code, flag problems early, and deliver ASP.NET applications that work in production — not just in development. Most of my clients come back for the next project. If you are scaling a SaaS product, modernizing a legacy system, or need an ASP.NET Zero foundation your team can build on — let's talk.
