# Improved

Existing production systems made faster, simpler, more reliable, or more automated.

<table><thead><tr><th width="218.359375">Project</th><th>Problem</th><th>What I changed</th><th>Result</th></tr></thead><tbody><tr><td><a href="https://github.com/near/threshold-signatures/pull/50">NEAR Threshold Signatures</a></td><td>Critical cryptographic paths were slow and had correctness and safety weaknesses.</td><td>Optimized measured bottlenecks and strengthened type safety, verification, CI, and memory/error handling.</td><td>Specific critical paths became <strong>~80× and ~5× faster</strong>, with stronger safeguards against crashes and correctness regressions.</td></tr><tr><td>Revision</td><td>Peak traffic caused poor performance, outages, and a race condition that could corrupt player data.</td><td>Built a simulator to reproduce the concurrency bug, stress-tested the backend, fixed shared-state handling, and addressed capacity bottlenecks.</td><td><strong>~10× higher throughput</strong>, reliability improved from <strong>~65% to 92%</strong>, and recovery dropped from minutes to seconds.</td></tr><tr><td>Vexor Network</td><td>Redundant requests increased latency and the beta lacked enough visibility and operational protection.</td><td>Added caching, validation, rate limits, monitoring, alerts, and safer release controls.</td><td><strong>~40% lower response times</strong> under expected load and no major technical incidents during initial rollout.</td></tr><tr><td>VENT Finance — AWS</td><td>Infrastructure was costing more than necessary.</td><td>Simplified and right-sized the AWS architecture while preserving critical performance.</td><td><strong>~60% lower monthly cloud cost</strong> with no documented performance regression.</td></tr><tr><td>VENT Finance — Ethereum</td><td>A core blockchain operation consumed excessive transaction fees.</td><td>Redesigned the transaction workflow around batching and verification.</td><td><strong>~99% lower transaction cost</strong> for that operation.</td></tr><tr><td><a href="https://github.com/milaforge/cybertechwatch">MCI</a></td><td>Repetitive security checks consumed engineering time and created opportunities for manual mistakes.</td><td>Automated repeatable security work and moved checks earlier into the delivery process.</td><td>Saved approximately <strong>3 team-hours per day</strong> and reduced repetitive manual work.</td></tr></tbody></table>
