I design and build reliable backend systems where correctness, structure, and long-term maintainability matter — especially when AI / LLMs are part of the solution.
Most of my recent work focuses on C#/.NET systems integrated with AI / LLMs, where natural-language input must be translated into structured, validated, and deterministic outputs (JSON, objects, schemas) that plug directly into real applications — not chatbots or prompt-only demos.
What I help clients with
AI / LLM integrations that produce predictable, schema-driven outputs
C# / .NET backend architecture and service design
Turning vague or messy requirements into clean technical models
Separating AI reasoning from core business logic for reliability
Designing systems that are easy to test, debug, and extend
How I approach AI work
AI is treated as a controlled component, not a black box
Outputs are validated before entering the system
Fallbacks and error paths are designed upfront
Clean interfaces and strong typing on the .NET side
This keeps systems stable even as models or prompts evolve.
Background & credibility
20+ years building and delivering business-critical software systems
Top Rated on Upwork with 100% Job Success
Long-term client relationships built on trust and consistency
Strong foundation in .NET, backend architecture, and cloud systems (Azure & AWS)
Hands-on experience with AI / LLM-based solutions beyond simple prompts
Working together
For long-term engagements, I offer a 2-week free trial, so you can evaluate how I work before fully committing. I’m also happy to share demos or walk through relevant examples on a short call.
If you’re looking for someone who prioritizes clarity, correctness, and reliability over hype, I’d be glad to connect.

Most hardware projects don't fail because of bad ideas. They fail in the messy space between "working prototype" and "shipping product." That's where I've spent the last 14 years — across 350+ projects and 50+ products now in mass production.
Hundred clients have come back for a second project. Here's what's behind that number.
I take products from napkin sketch to factory floor — designing the PCBs, writing the firmware, and optimizing the BOMs. That DFM work alone typically saves clients 20–30% on production costs. One client shipped at 12mA after coming to me with a prototype drawing 800mA in sleep mode. That's the difference between a redesign and a launch.
The firmware I write runs 24/7 in industrial environments where a crash at 2 AM means someone's driving to a job site. I build for reliability first: FreeRTOS or bare-metal on STM32, ESP32, nRF52/53, RP2040, PIC, and Atmel. Connectivity — MQTT, BLE, Wi-Fi, LoRa, or cellular — gets chosen for the use case, not the trend.
On the hardware side: multi-layer PCBs, proper signal integrity, IPC-compliant layouts (2221, 7351) in Altium and KiCad, built for manufacturability from day one. When the project calls for it, I wire the full IoT stack — AWS IoT Core, edge AI/ML inference, secure OTA, and fleet health monitoring.
Top-Rated Plus. 100% Job Success Score.
If you need an engineer who thinks in yield rates, field reliability, and unit economics — hit "Message" or "Invite to Job." Let's get your product out the door.

I help companies stabilize, modernize, and extend production .NET applications.
I am a senior .NET and C# developer with 13 plus years of experience working on existing enterprise codebases in C#, ASP.NET Core, ASP.NET Web API, SQL Server, Azure, Angular, and React. Most of my work is not greenfield. It is the hard part. Legacy .NET Framework apps, slow APIs, fragile integrations, performance bottlenecks, data issues, and new features that need to ship without breaking what already works.
I am comfortable with long running projects, messy code, and complex business logic. If you need someone who can step into an existing system and make safe, useful changes, that is the work I do best.
What I can help with
ASP.NET Core, C#, and .NET backend development
REST API development, third party integrations, authentication, and background jobs
Legacy modernization from .NET Framework, ASP.NET MVC, and Web API to modern .NET
SQL Server schema design, stored procedures, query tuning, and data fixes
Azure deployments, Azure DevOps, CI CD, and production support
Angular or React front ends integrated with .NET APIs
Bug fixing, refactoring, performance tuning, and scaling existing systems
When AI is actually useful, I also build AI workflow automation and RAG systems inside existing .NET applications. That includes OpenAI API integrations, document extraction, internal knowledge search, summarization, approval workflows, logging, fallbacks, and human in the loop review.
