Why work with one full-stack developer instead of a team?

Web, mobile, backend — all handled by one person. No back and forth between multiple people. Faster iteration, clearer communication.

How fast can you deliver projects?

Quick turnarounds without cutting corners. Your deadline is taken seriously and always kept in sight.

Do I communicate directly with the developer?

No middlemen, no delays. Just clear, honest communication from start to finish, every time.

Is the code maintainable and scalable?

Clean code that's easy to scale, maintain, and hand off whenever you need to move forward.

Do you understand startup constraints?

Lean mindset, tight budgets, real deadlines — I've been there, I understand what actually matters.

Overview

ChatZapp is an AI chat platform that uses Solana wallet authentication. Users stake credits to interact with personality-driven agents powered by LLM APIs. The project combines token-based credit systems with lightweight Web3 integrations for on-chain identity verification.

Brief & Challenge

The goal was to create an AI chat experience with Web3-native identity — no email signup, just wallet connect. Users needed a credit system to gate AI usage and a way to interact with distinct AI personalities.

Approach & Decisions

Integrated Solana wallet adapter for authentication, built a credit staking mechanism, and connected OpenAI API with custom system prompts per agent. PostgreSQL stores conversation history and user credits. The architecture separates Web3 logic from the chat layer for maintainability.
