You will get Tech Stack Consultation | .NET Developer | Full Stack Dev
Top Rated
Project details
You are building something new — or rethinking an existing system — and stuck on: .NET vs Node.js, SQL Server vs PostgreSQL, monolith vs microservices, C# vs Python.
I am a Senior .NET Developer and Full Stack Developer who has made these decisions across FinTech, HealthTech, EdTech, and SaaS — and I know which choices age well and which become expensive regrets.
In this consultation we cover:
Backend stack: .NET Core vs Node.js vs Python — team skills, scaling needs, and maintenance cost.
Database: SQL Server vs PostgreSQL vs MongoDB — based on data model, query patterns, and cloud deployment.
Architecture: monolith vs microservices — the honest answer based on team size and actual load requirements.
Frontend alignment: which frontend stack connects cleanly to your backend without unnecessary friction.
Migration strategy: if considering a switch — what it costs, what you gain, and whether it is worth it.
Done = clear stack recommendation, trade-offs explained, written decision notes within 24 hours.

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.
