Solana Lending Protocol
Built the risk engine, Anchor programs, SDK, and launch tooling behind a Solana lending network that reached $12.4M TVL after launch.
Built the risk engine, Anchor programs, SDK, and launch tooling for a Solana lending product that reached $12.4M TVL after go-live and cleared audit with no critical findings.
Built with
“Built the entire Solana stack: contracts, SDK, front end, and monitoring.”
Marcus T.
CTO, DeFi Protocol
The Challenge
The client needed a secure, production-ready lending protocol on Solana but lacked in-house depth in Anchor, risk modeling, and DeFi operations. They needed one senior builder who could take the product from architecture through launch.
The Solution
I built the protocol end to end: Anchor programs with defensive guardrails, a typed SDK, admin tooling, and the operating playbooks required for launch. The system cleared audit without critical findings and went live with monitoring and parameter controls already in place.
Key results
Across mainnet-beta and validation environments
No critical findings
No launch-day pages or emergency pauses

Week 9
Audit support, launch checklist, monitoring, and runbooks
Project Details
Technical implementation and architecture overview
Risk-aware lending primitives
Designed collateral factors, liquidation hooks, and oracle integrations with property tests and debt-ceiling guards to keep the protocol operable under stress.
Typed SDK and operator console
Delivered a TypeScript SDK, CLI, and admin tooling so the team could manage assets, update parameters, and inspect protocol state without relying on raw RPC calls.
Launch hardening and monitoring
Built dashboards, alerting, and operational runbooks so the launch was managed like a live financial system rather than a code drop.
FAQs
How much does it cost? +
Complete projects start at $2,000. I give you a fixed price after a free 30-minute call — no hourly billing, no surprise invoices.
How fast can you deliver? +
Most MVPs go live in 2–4 weeks. Larger projects run in 2-week sprints with a live demo every week so you always see progress.
Who will actually build my product? +
Me. Personally. I have 10+ years of experience and I handle everything — frontend, backend, infrastructure, deployment. No outsourcing.
What makes you different from agencies? +
No overhead. You talk directly to me — the person writing the code. That means faster decisions, better output, and lower cost.
What if I need changes after launch? +
You get 30 days of free post-launch support included. After that, I offer affordable monthly retainers or project-based work.
What technologies do you use? +
TypeScript, React, FastAPI, Node.js, Python, Rust, Solidity, React Native, Flutter — I pick what fits your project, not what's trendy.
Can one person really handle everything? +
Yes. Frontend, backend, infrastructure, mobile, and Web3. With 10+ years of experience and AI-accelerated workflows, I consistently deliver what agencies need 10 people to build.
Do you use AI to write code? +
Yes. I use AI as a force multiplier — for code generation, review, testing, and documentation. It's why I ship 3x faster than traditional developers. But every line is reviewed, tested, and refined by me before it touches your project.
Is your code production-ready? +
Yes. Every project I deliver is production-grade — tested, optimized, secure, and deployed to real infrastructure. I don't hand off prototypes. You get code that's ready for real users from day one.
What if my project doesn't work out? +
You own everything I build — every line of code, every design file. If you want to walk away or bring in another team, you can. No lock-in.
