My SaaS-style web platform is already about 90 % complete; what I need now is a seasoned full-stack developer who excels at stepping into an existing codebase and driving it across the finish line. The top priority is thorough bug fixing and system testing. I expect a balanced mix of manual exploration and automated test suites so we can catch both edge-case glitches and any regressions before launch. Scope of work • Run a full test pass, document defects, and patch them. • Validate and, where needed, correct the usage-limit logic that controls free vs. paid quotas. • Polish the UI for mobile, tablet, and desktop breakpoints so every component renders cleanly and responsively. • Integrate the remaining ad slots and confirm the affiliate and withdrawal flows function end-to-end. • Make sure all real-time counters stay in sync across views. • Profile and tune performance—both server-side and front-end—to keep load times snappy. • Tackle a handful of small feature tweaks that surfaced during beta. I’ll provide full repo access, staging credentials, and an outstanding issues list. You’ll keep me updated through concise daily notes and push incremental PRs so we can review changes continuously. If digging into someone else’s code, stabilizing it, and delivering a rock-solid, production-ready release is what you do best, let’s talk.

Hello, I read your description carefully. Stepping into a codebase that is 90% finished is usually less about coding and more about identifying hidden regressions before launch. The sensitive area here is the usage-limit logic for free vs paid quotas. If counters, quotas, and real time updates are not validated together, users often bypass limits or see inconsistent data across views. My approach is to run a structured test pass, patch issues in small PRs, and verify flows like ads, affiliate payouts, and withdrawals end to end. I also profile server and frontend paths so performance stays stable under real traffic. My responsibility is to make the release predictable and production ready. If this direction fits your plan, we can review the repo and priorities. Warm regards, Ivan
