Insights
How these are computed- Run-rate, measured
- pending
- Needs two observations at least 14 days apart. Our next read of this page turns this on. Nothing is extrapolated from a single contract.
- Lifetime pace
- $14.2K/yr estimate
- Lifetime earnings divided by years on Upwork. A floor on historical pace, not a forecast.
- Earnings per job
- $6.8K
- Average contract value to date.
- Recent earnings, per Upwork
- $0
- The "recent" figure Upwork attaches to the directory card. Upwork does not publish the window, so it is shown as its number, not ours.
- Realised hourly
- $55/hr
- Total earned over billed hours. Fixed-price work inflates it; compare with the rate card.

About
We are Chainza, a team of full-stack engineers building scalable SaaS platforms, web applications, mobile apps, and blockchain-based products. Our core focus is delivering production-ready software with strong architecture, clean UX, and reliable backend systems. Our team is built around top engineering talent from the Ukrainian market, particularly graduates from mathematics and IT faculties. We focus on engineers with strong foundations in TypeScript, React, Next.js, Node.js, Go, and Python, combined with clear communication and real-world delivery experience. Alongside our full-stack work, we maintain a dedicated Web3 track. Engineers go through internal training in blockchain, DeFi, and smart contract development, with specialization paths in frontend, backend, full-stack, or smart contracts. This allows us to support both traditional SaaS platforms and advanced blockchain integrations when needed. We typically work on: - SaaS platforms and internal systems - Marketplaces and user-facing platforms - Dashboards and data-heavy applications - API integrations and automation workflows - Fintech and payment-related systems - Mobile applications (React Native) - Web3 products such as dApps, smart contracts, and wallet integrations - Cross-chain and blockchain infrastructure solutions Our tech stack includes TypeScript, React, Next.js, Node.js (Express), Go, Python, PostgreSQL, AWS, and React Native for mobile, along with Web3 technologies such as Ethers.js, Web3.js, Solidity, Hardhat, and Truffle. If you’re looking for a team that can take a product from idea to production, or scale an existing system with solid engineering practices, we’d be glad to connect.Read more
