I will build high performance cross platform desktop software


About this gig
Need robust, high-performance desktop software?
I am a software engineer specializing in C++, Java, and secure backend architecture. If you need a serious desktop application - whether it's a cross-platform GUI tool, a data processing utility, or a secure communication app - I can build it from the ground up.
What I Specialize In:
- GUI: Developing intuitive, scalable interfaces using Qt or Java.
- High-Performance Core: Multithreading, memory optimization, and complex logic in C++.
- Security & Cryptography: I have hands-on experience building an E2EE messenger from scratch, utilizing custom binary protocols and elliptic curve cryptography. Your data security is a priority.
- Integrations: Connecting your application to local databases (SQL/NoSQL) or external APIs.
My Approach: I write clean, production-ready code. I focus on stable architecture and realistic deadlines. If a feature is technically unfeasible or requires a different approach, I will tell you directly.
Tech Stack: C++, Java, Qt, Cryptography, SQL.
Important: Please message me with your technical requirements before placing an order. We need to discuss the scope to ensure the timeline and budget are accurate.
