" summary

Built a cross‑platform wallet called Phoenix in a single monorepo using Angular+Electron for desktop and React Native for mobile, with a shared NPM library BurstJS managed by Lerna. Wallet derives accounts from a passphrase, signs transactions client‑side and broadcasts them; CI with Travis runs builds, tests and nightly releases, library tests hit ~93% coverage. Demo shows publishing a Java smart contract to the Burst testnet (activation fee set, execution cost 4, timeout 1440 minutes); deployment takes several blocks but the contract deploys and responds as expected.
