Most clients reach out to me after struggling with slow .NET development, messy codebases, and APIs that break under scale. That usually happens when projects are built without the right architecture from day one. If you’re looking for a .NET Developer who builds fast, scalable, and production-ready systems, while using modern AI-assisted development to move quicker without sacrificing quality, you are in the right place. With 8+ years of experience as a .NET Full-Stack Developer, I combine deep expertise in C#, .NET Core, ASP.NET Core, ASP.NET MVC, and Web API with AI tools like Cursor, Claude, and GitHub Copilot to deliver high-quality .NET solutions faster than traditional development approaches. WHAT I DO AS A .NET DEVELOPER I specialize in building complete, end-to-end .NET applications — from backend architecture to frontend delivery and cloud deployment. My work includes: • ASP.NET Core API development — REST APIs, scalable Web APIs, and modern backend systems using .NET 6 and .NET 8 • C# backend development — Clean Architecture, CQRS, Domain-Driven Design (DDD), and SOLID principles • Full-stack .NET development — ASP.NET Core backend with React.js or Angular frontend • .NET Microservices architecture — distributed systems using ASP.NET Core, Docker, Kubernetes, and Azure Service Bus • Entity Framework Core — optimized database design with SQL Server, PostgreSQL, and Azure SQL • Third-party API integrations — Stripe, PayPal, Twilio, Plaid, and external services • Background jobs & event-driven systems — queues, schedulers, and scalable processing in .NET AI-ASSISTED .NET DEVELOPMENT I use AI as a real productivity tool — not just a buzzword. With Cursor, Claude, and Copilot integrated into my workflow: • ASP.NET Core APIs are developed faster with less boilerplate • C# code quality improves through AI-assisted reviews • Debugging complex .NET applications becomes quicker and more efficient • More focus goes into architecture, scalability, and system design This means you’re not just hiring one developer — you are getting the output of an optimized, high-efficiency development process. ASP.NET CORE & API DEVELOPMENT ASP.NET Core is at the core of everything I build. Every API I develop is: • Secure — JWT authentication, OAuth2, Azure AD integration • Scalable — built for cloud environments like Azure • Clean — structured using best practices like Clean Architecture • Documented — Swagger/OpenAPI included by default • Tested — unit and integration testing with xUnit / NUnit • Maintainable — versioned and ready for long-term scaling Whether it’s a new API, scaling an existing system, or modernizing legacy .NET applications — I focus on clean, reliable delivery. FULL-STACK .NET DEVELOPMENT I build complete systems where backend and frontend work seamlessly together: • ASP.NET Core + React.js (TypeScript-based modern apps) • ASP.NET Core + Angular (enterprise-grade applications) • Real-time applications using SignalR • Full database integration with SQL Server / PostgreSQL CLOUD & MICROSERVICES (.NET + AZURE) I design and deploy scalable cloud-native applications using Microsoft Azure: • Azure App Services, Azure Functions, Azure SQL • Azure Service Bus for event-driven architecture • Microservices using ASP.NET Core and Docker • Kubernetes (AKS) for container orchestration • CI/CD pipelines using Azure DevOps MY APPROACH Every project follows a structured approach: • Understand business requirements before coding • Design scalable architecture upfront • Use AI-assisted development to speed up delivery • Write clean, testable, production-ready .NET code • Stay available for improvements, scaling, and long-term support KEY PROJECT EXPERIENCE • Built HIPAA-compliant healthcare platform using .NET Core, ASP.NET Core Web API, and React.js, improving performance and data security • Developed microservices-based systems using ASP.NET Core and Azure, improving scalability and system reliability • Integrated third-party APIs (Stripe, PayPal, Twilio, Plaid) using .NET Web API, automating workflows • Migrated legacy applications to modern .NET Core / ASP.NET Core architecture on Azure, reducing infrastructure cost • Built enterprise platforms (CRM, LMS, SaaS, POS) using C#, ASP.NET MVC, .NET Core, and Entity Framework SERVICES I OFFER • ASP.NET Core web application development • .NET Web API & backend development • C# backend system design • Azure cloud architecture & deployment • Microservices development using .NET • Full-stack development (React.js / Angular + .NET) • API integrations & third-party services

I help engineering teams and technical founders make the right system decisions before they become expensive — scoping what to build, de-risking architecture before irreversible choices are made, and owning delivery through to scale. My background spans cloud architecture, solution architecture, and database systems across AWS and Azure. The combination matters: most production failures I have seen trace back not to bad code, but to structural decisions made early in the schema, the system boundaries, or the deployment model — that compounded quietly until they could not be undone. I am based in Armenia and work async-first with clients across the US, Europe, and Australia. Architecture work — system design, technical reviews, decision documentation, governance frameworks — does not require timezone overlap. My clients do not experience geographic friction. 🔹 𝐓𝐡𝐫𝐞𝐞 𝐫𝐞𝐜𝐞𝐧𝐭 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐭𝐡𝐚𝐭 𝐜𝐚𝐩𝐭𝐮𝐫𝐞 𝐡𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤: 𝐆𝐃𝐂 𝐌𝐞𝐝𝐢𝐚 (𝐈𝐫𝐞𝐥𝐚𝐧𝐝) — built an LLM-assisted database audit engine running across 3 MySQL clusters and 15 production nodes. 13 independent checkers feed findings to the LLM, which grades each as Critical / Major / Minor / Trivial and writes a short, grounded explanation. Runs hands-off 365 times a year. 𝐇𝐑𝐒 𝐆𝐫𝐨𝐮𝐩 (𝐂𝐨𝐥𝐨𝐠𝐧𝐞, 𝐆𝐞𝐫𝐦𝐚𝐧𝐲) — designed and built financial data pipelines on AWS that bridge MS Navision (ERP) and SAP through a single canonical model. Safe to replay, with scheduled reconciliation. 𝐆𝐥𝐚𝐬𝐬𝐰𝐚𝐥𝐥 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 (𝐔𝐊) — Cloud Engineer on the Content Disarm and Reconstruction platform now trusted by NATO and U.S. and U.K. national security agencies. Helped adapt the platform for AWS EKS, Azure AKS, and K3s, and built the file ingress orchestration plugin handling terabytes of potentially infected files. 🧭 𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤 I don't approach projects as feature delivery. I approach them as temporary or ongoing technical ownership — short engagements that clarify direction, longer ones that carry the system through to scale. The shape is the same in both: • Reduce MVP scope while keeping the core value loop intact • Define cloud architecture and system constraints before implementation begins • Make decisions explicit instead of accumulating quiet assumptions • Separate short-term delivery from long-term structural risk • Hand off to in-house engineers cleanly when the moment is right Some engagements take two weeks. Some turn into multi-year work. The goal in both is the same — systems that don't need heroics to keep running. 🎯 𝐖𝐡𝐞𝐫𝐞 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐮𝐬𝐮𝐚𝐥𝐥𝐲 𝐠𝐞𝐭 𝐬𝐭𝐮𝐜𝐤 In early- and growth-stage systems, the biggest problems are rarely about tooling or raw engineering skill. They are decision gaps: • Feature lists that grow faster than clarity • AI is treated as a black box instead of a constrained system • Developers hired before the success criteria are defined • Architectural decisions deferred until they're expensive to reverse • "We'll fix it later" choices that quietly become permanent That's the layer I focus on stabilizing first — so execution stays fast without becoming brittle. ⛁ 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞 𝐚𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 & 𝐝𝐢𝐚𝐠𝐧𝐨𝐬𝐭𝐢𝐜𝐬 Production databases are where architectural decisions surface most visibly — slow queries, bloated indexes, configuration drift, schema choices that worked at 10K rows and break at 10M. I have extensive hands-on experience with PostgreSQL, MySQL, and MariaDB in high-load production environments. For teams that need a fast, structured assessment: I offer a fixed-price SQL database audit via my Project Catalog — a prioritized diagnostic report delivered in 1–2 days, ranked by business impact. 🧱 𝐒𝐭𝐚𝐜𝐤 • Databases — PostgreSQL, MySQL, MariaDB, OpenSearch, Elasticsearch, DynamoDB • Cloud — AWS, Azure, Kubernetes, Docker, serverless • Security — IAM, encryption, access boundaries, secure data flows • DevOps — CI/CD, GitHub actions, CloudFormation, observability • AI-adjacent — guardrails, confidence gating, deterministic vs. generative boundaries Technology serves decisions, not the other way around. 📅 𝐄𝐧𝐠𝐚𝐠𝐞𝐦𝐞𝐧𝐭 𝐟𝐨𝐫𝐦𝐚𝐭𝐬 • Long-term architecture and delivery ownership • Fractional CTO or technical advisor • Short-term advisory (1–4 weeks) • Fixed-price SQL database audit (Project Catalog — from $750) Most successful collaborations start small and grow naturally once alignment is in place. 📨 𝐋𝐞𝐭'𝐬 𝐭𝐚𝐥𝐤 If you are unsure what to build, what to cut, or how to de-risk a critical phase — or if your database is showing signs of trouble — a short conversation usually makes sense. From there, we decide together on the right shape of engagement.
