Auditar app de lovable Tengo mi app Lovable casi lista, pero aún quedan varios detalles técnicos antes de publicarla.

Conectar la API de la base de datos de artículos científicos que ya tengo seleccionada, mostrando los resultados dentro de la interfaz actual. 2.

I have an existing React web application and a Capacitor-wrapped mobile build called “My Magic Pencil.” It teaches by drawing live illustrations while it explains concepts, and I now need three tight upgrades: First, I want the iOS version shipped to the App Store. That means configuring the Capacitor project for Apple compliance, integrating in-app purchase for the subscription tier, setting up App Store Connect metadata, and guiding it through TestFlight review until approval. Second, the current interface feels rough. Start by manually walking through every feature on the website (this is the priority platform) and correcting any mis-aligned components, sluggish buttons, or visual glitches. Once the web version is spotless, repeat the same hands-on testing and polish for A...

I run a software company that handles a steady stream of customer enquiries every day, and I need a reliable hand to keep our users happy. Your core task will be installing and troubleshooting our applications on both Windows and macOS systems, then replying to customers by email with clear, friendly updates that match the simple response templates I provide. Because many of our users are non-technical, you will occasionally jump into a remote-access session (any standard tool you are comfortable with is fine) to walk them through the fix or complete the install for them. A fast typing speed and good written English are essential so every message feels personal yet professional. Work rhythm • 10 hours daily, 30 days a month • Initial commitment of at least one year, renew...

I need the “Dynamic Pricing / Dynamic Price Range” plugin on my WooCommerce store to ignore the regular price and calculate all discounts from the Wholesale Suite price whenever a customer is logged in as a wholesale user. Right now wholesale shoppers see no discount at all because the plugin still references the regular price. My flash sales are usually fixed-amount discounts, so the adjusted logic must handle that scenario first, though it should remain compatible with any other rule types already supported by the plugin. The work involves: • Rewriting the plugin’s price-retrieval logic so every tier, cart rule, schedule, and shortcode tied to dynamic pricing pulls the wholesale price returned by Wholesale Suite. • Maintaining full compatibility with e...

I’m running a ZKtec Biotime deployment that has begun throwing software errors I can’t pin down. My immediate goal is to get the system fully stable again and understand the root cause of the bugs, whether they stem from the database, the Biotime service, or an interaction with the operating system. Here’s what I need from you: • Diagnose the recurring software errors in my current Biotime installation. • Apply fixes or patches to remove the bugs and restore normal operation. • Document what went wrong, how you resolved it, and any preventive steps I should take. Access will be provided to the server via remote session at a mutually convenient time. I’ll also share the exact error logs I’m seeing so you can start investigating right away....

I’m looking for a patient, hands-on mentor who can walk me through SAP Fiori configuration and setup from the ground up. My background in this area is beginner level, so I need clear explanations, real-time demonstrations and plenty of practical exercises that I can replicate in my own sandbox. The focus is strictly on Fiori—security, GRC and other SAP domains can stay on the sidelines for now. I’d like to start with the core tasks: activating standard apps, managing catalogs, groups and roles, troubleshooting common gateway and OData issues, and understanding the best practices behind each step so I can build a solid foundation before moving on to more advanced customization later. Here’s how I picture the engagement: • Short, regular live sessions (screen...

I’ve recently launched a cloud-based CRM and project-management suite and need a fresh set of eyes to evaluate how intuitive it feels for its main audience—software developers. Your mission is to walk through real-world developer workflows, stress the visual layout, and tell me where the interface delights or frustrates. What I care about most is the overall user-interface design: spacing, hierarchy, iconography, colour choices, wording—anything that speeds up or slows down a developer who just wants to create a project, log issues, or track client conversations. While navigation flow and on-screen guidance are always welcome comments, the primary scorecard is the look-and-feel and how quickly new users “just get it.” Deliverables (all discrete and easy to t...

I have an existing web application that must be pulled apart and inspected from every angle so we can see exactly where it breaks. The assignment centres on software-level reverse engineering, with the single overriding goal of identifying security vulnerabilities in the code base and its runtime behaviour. Once we confirm your availability I will provide the full application bundle, test server images and any credentials you might need. Your analysis should combine static code inspection with dynamic testing: think Burp Suite for traffic interception, Wireshark or similar packet capture, plus any de-obfuscation or disassembly tools (IDA Pro, Ghidra, etc.) that help you drill into compiled assets. Please follow OWASP guidelines so results are mapped to familiar risk categories. Deliverab...

I need a straightforward internal app that lets our country managers key in current prices or a price range for every product we sell, then instantly makes those numbers visible to the sales team. The same code-base should compile for iOS, Android and load in any modern browser so nobody is left out in the field. Core workflow • Country Managers log in and enter or edit prices once a week or bi-weekly or as frequently as they like. Leave it flexible • Sales reps open the app and see those figures laid out in a clean, sortable grid. They can flip the time selector to view prices for today, this week, or the last two weeks without downloading a separate report. • No fancy analytics—just fast loading, clear typography and a search bar so a rep can find an SKU in seco...

I’ve uploaded a small bundle of C++ source files, their accompanying database dump, and the HTML / CSS front-end that sits on top of them. A few issues crept in that I can’t pin down: • the C++ code will not compile cleanly – basic syntax errors keep popping up • the database schema needs a quick rationalisation for speed and consistency • several layout glitches appear in the HTML / CSS, and the labour-cost figure returned to the page is wrong What I need from you is simple: return fully working copies of each file along with a brief note of what you changed and why, so I can follow the fixes later. Tested, readable code is a must; if you use tools such as clang-format, MySQL Workbench, or browser dev tools, great—just mention them so I know ho...

I want to commission a lightweight yet capable image-editing application focused on everyday graphic tasks rather than the full complexity of a Photoshop clone. The core of the brief is simple: the finished tool must let me open common raster formats, work across multiple layers, add editable text, and apply a solid set of real-time filters. Key functionality I need implemented • Layer management: create, reorder, hide, lock, and adjust opacity on layers. • Filters & effects: at minimum include non-destructive color-correction controls (brightness, contrast, levels) and several blur options (gaussian, box, motion).

I have a Flutter-based IPTV player that runs on Android TV and I need help stabilising its performance. The core problem is general playback optimisation: every channel and video suffers from buffering or lagging, occasional crashes or freezes, and noticeably low video quality.

Deliverables • Updated Flutter code with clear comments...
