I have an existing Android APK but no accessible source code. I need the app fully de-compiled, cleaned up, and re-assembled so I can continue development. Once the codebase is restored, I’ll want a few targeted edits—mostly refactoring and minor feature adjustments that we’ll clarify together after you review the decoded project. What I expect from you: • Produce a readable, gradle-based Android Studio project reconstructed from the current APK. • Implement the agreed code changes, then compile and deliver a fresh, working release APK plus signed debug build. • Document every modification so I can pick up future work without hand-holding. You’re free to use jadx, apktool, or any equivalent reverse-engineering toolchain as long as the final pr...

I need a robust, well-documented software or a tool that lets the Zowee H155-381 operate with several SIM cards instead of only one. The job involves reverse-engineering the device’s firmware and hardware interfaces, pinpointing the current SIM-handling logic, and producing a tool that can reliably switch between multiple SIMs on demand. The core requirement confirm that you will deliver: A working unlock software for Zowee H155-381 same model shown at pictures i sent that single or double click do steps automatically and make every router we link and use the software on it support multi carriers sim card normally without future re locking Network/SIM lock removal, so the device can be used with other carriers normally without any obstracles Step-by-step instructions (easy...

I need an experienced engineer to analyze and improve a high-demand online booking workflow so bookings can succeed reliably even under extreme traffic. I already have a working Playwright-based browser automation, but during peak demand all sessions currently land on a “high demand / unavailable” state. The goal is to improve success rate through deeper system understanding, better timing, and smarter flow control . The work involves analyzing booking flow and state transitions, understanding how availability actually appears during high demand (including delayed or staggered releases), improving timing, retries, waiting strategy, and navigation logic, eliminating race conditions and aborted navigations, and designing the automation to be long-running, reactive, and resilient ...

Our Python-based platform has been in production long enough to accumulate a handful of thorny issues. I want a fresh, senior-level pair of eyes to go through the codebase, diagnose what’s really happening, and bring the system back to a stable, performant and secure state. Scope of the audit • Security: probe for obvious misconfigurations, insecure dependencies, injection risks and any surface that could be exploited. • Performance: profile critical paths, highlight bottlenecks, and suggest optimisations that translate into measurable speed-ups or lower resource usage. • Code quality: evaluate structure, readability and test coverage; recommend refactors that reduce technical debt. Highest priority fix Functionality issues come first. Anything preventing cor...
