About this gig
Scale your social vision with an enterprise-grade technical foundation.
With 14+ years of experience in high-concurrency systems, I specialize in building the engines behind successful social platforms. I don't just provide code; I provide a scalable architecture designed to handle growth, ensure data privacy, and deliver real-time engagement.
Core Expertise:
- Real-Time Engines: Sub-millisecond message delivery using Socket.io and WebRTC.
- Intelligent Matching: Custom logic for geolocation, preference-based filtering, and compatibility scoring.
- Privacy-by-Design: Implementation of Argon2id key derivation and AES-256 encryption for sensitive user data.
- Scalable Backend: Efficient Node.js or Python environments built for high-traffic stability.
Whether you are building a niche dating app, a community portal, or a professional networking site, I ensure your project starts with a professional, secure, and documented foundation.

FAQ
What exactly do I get in the $300 Basic Tier?
This tier is designed to build the "Brain" of your app. You receive a professional database schema, a secure User Authentication system (JWT/Bcrypt), and a technical API roadmap. It ensures that when you move to full-scale UI development, your foundation is enterprise-ready.
Can you scale the platform as my user base grows?
Yes. I architect systems using Node.js and PostgreSQL/MongoDB, which are designed for horizontal scaling. The "Basic" roadmap I provide explicitly plans for this growth.
Is my data secure in the matching engine?
Absolutely. I implement "Security-by-Design," including data encryption at rest and secure session management with automatic timeouts to protect your users.
Will I own the code once we finish?
Yes. All code developed for your project is "Work for Hire." You receive full ownership, documentation, and the credentials needed to manage the project independently.
