FAQs
What blockchains do you work with?
I specialize in Solana (advanced proficiency) and EVM chains including Ethereum, Polygon, Arbitrum, and Binance Smart Chain. I can handle smart contract development, deployment, and full-stack dApp integration across these ecosystems. If your project requires a different chain, I can assess feasibility during our initial consultation.
How long does a typical project take?
Timeline depends on complexity: Smart contract deployment: 3-7 days Token launch with basic infrastructure: 2-3 weeks Full-stack dApp (frontend + contracts): 3-6 weeks Complex DeFi protocols: 8-16 weeks I provide a detailed timeline after reviewing your requirements. I prioritize speed without compromising code quality or security.
Do you provide post-delivery support?
Yes. All projects include 1-2 weeks of post-delivery support for bug fixes, questions, and clarifications at no additional cost. For ongoing maintenance, updates, or feature expansion, I offer retainer packages or project-based support—we can discuss this based on your needs.
I'm not technical—can you still work with me?
Absolutely. I handle the entire technical lifecycle and explain everything in plain language. You don't need to understand Rust or Solidity—just tell me what you're trying to build and what problem you're solving. I'll translate your business requirements into working code and walk you through the final product.
Do you handle both smart contracts and frontend development?
Yes, I'm a full-stack blockchain developer. I build the entire application: smart contracts (backend logic), frontend interface (React/Next.js), wallet integrations, and deployment infrastructure. You get a complete, production-ready product—not just a contract that sits there doing nothing.

Collaborating with Bojan on CyberLink Security, solmint.dev, and watchguard.dev has been genuinely transformative for me and for the projects we’ve shipped together. He combines deep cybersecurity, security software architecture, and blockchain forensics expertise with real empathy and patience as a mentor—he helped me grow from total beginner to confident collaborator without ever making things feel overwhelming. He’s meticulous, calm under pressure, and genuinely invested in protecting people
