Project details
You have an idea or a half-formed plan, but you're not sure what to build first, what it will cost, or which technology to use.
In 30 minutes we'll turn that into a clear, actionable picture.
I'm a .NET Developer and Full Stack Developer with experience across FinTech, HealthTech, SaaS, and EdTech — from greenfield products to legacy modernisation and AI-powered features.
What we cover in the session:
• Idea alignment: gather your goals and define what the project actually is
• Scope definition: what's MVP, what's phase 2, what's out of scope
• Tech stack recommendation: which technologies fit your case and budget
• Rough estimate: realistic timeline and cost range
• AI acceleration: where AI tooling can cut build time and reduce costs
• Next steps: a prioritised action plan you can take to any developer
No lengthy process. No commitment. Just clarity on what to build, how, and what it will take.
What's your project: new product, existing app, or internal tool?

Full Stack .NET Developer Needed to Help With Payment Integration
Daria did a great job helping us fix our Stripe integration in a .NET app. She quickly found why webhooks weren’t updating the order status and guided us through a clean solution. Clear communication, fast turnaround, and very easy to work with. Would definitely hire again.

As a Full Stack Developer, .NET Full Stack Developer, and experienced Web Developer, I help companies build scalable SaaS platforms, CRM systems, and enterprise-grade solutions.

For frontend development, I’ve used Angular, jQuery, TypeScript, Vue.js, React.js, and Blazor to build interactive, responsive user interfaces fully integrated with .NET-based architectures.
Throughout my 10+ years in development, I’ve also worked with major databases like MsSQL (EF), MySQL, PostgreSQL, MongoDB, Redis, and Azure SQL Database, as well as cloud platforms such as Microsoft Azure, Azure Containers, Azure App Services, and Azure Data Factory.
In addition, I have strong experience in AI and automation, working with OpenAI API and Dify AI to create smart, data-driven software solutions.

I’ve also worked with mobile technologies such as Flutter, Dart, FlutterFlow, Supabase, Firebase Auth, Android, iOS, and general mobile app development.
My core expertise remains as a Full Stack Developer and .NET Developer, designing clean architectures (MVC, Microservices, Event-Driven), integrating AI tools as a Full Stack Developer AI, and delivering reliable cross-platform systems as a Mobile App Developer.
If you're searching for a Web Developer, React Developer, WordPress Developer, Python Full Stack Developer, Full Stack Developer Shopify, or .NET Full Stack Developer, I’m ready to collaborate
