I’ve lined up a series of tasks to turn a concept into a fully-functioning web application, and everything needs to be written in Python. You’re free to choose between Django or Flask for the backend—whichever lets you craft clean, secure APIs and a maintainable codebase fastest. Here’s what I need from you: • Spin up the project skeleton, configure the environment, and set up version control. • Build out the core routes/endpoints, wire them to a relational database (PostgreSQL or MySQL work fine), and keep the code modular for easy scaling. • Create a simple but responsive front-end that consumes those endpoints and showcases at least one complete user flow (think registration, login, basic CRUD). • Add concise documentation that...

I have an idea for a truly “lovable” AI-driven mobile app, but I need an experienced developer who can help shape the concept, recommend the best tech stack, and then bring the entire product to life. The core goal is simple: create an AI experience that users emotionally connect with and want to keep opening every day. I’m flexible on platform (iOS, Android, or a shared code base) as well as on the exact AI use-case—whether it ends up a conversational companion, a smart personal assistant, or a recommendation engine will depend on what we decide together fits the market and the technology best. What matters most is polished UX, ethical data handling, and an engaging personality that feels genuinely helpful rather than gimmicky. Here’s how I picture the ...

I have two immediate needs that can run in parallel if you’re comfortable with both disciplines. First, a significant volume of information must be keyed in by hand. Accuracy is critical, so I’m looking for someone who can type quickly while double-checking their work. The source files are tidy and well organised; you’ll simply transpose the fields into my preferred format (Excel, Google Sheets, or directly inside the site’s CMS—whichever you’re fastest with). Alongside that, my website could use an experienced developer’s touch. I haven’t locked myself into a single priority yet; whether you shine at refreshing layouts, tightening up back-end functionality, or refining on-page copy, I’m open to suggestions. If you specialise in Wo...

...guide the process. The core of this engagement is simple: you design a stream of bite-sized yet progressively challenging coding tasks, I complete them, and you review my work with clear, actionable feedback.

I need a lightweight Android application that can reliably record both-party audio on voice calls. The main goal is personal archiving, so clarity of the captured sound on each side matters more to me than fancy UI touches. Target devices My day-to-day phones are Oppo, Vivo, Redmi and OnePlus models running recent Android builds (I can ship a test handset if that helps). The finished APK should install cleanly and work without root on those brands; if a minimal permissions tweak or foreground service is unavoidable, let me know early so I can approve it. Required feature set • Two-way call recording that survives the manufacturer’s call-recording blocks and new Android privacy changes. • An in-app call history log showing date, contact/number and recording le...

I need my live Odoo 15 Enterprise instance on upgraded to version 19 while ensuring smooth operation. The core platform upgrade is straightforward; the main focus is on three custom modules that handle Australian phone-number formatting and phonebook sync, manage wholesale vs. retail price displays, and add weight calculations to paperwork. Since these modules have never undergone a major version upgrade, their data models and views require careful migration. Custom module details: Split one module into separate components: • A module for reformatting phone numbers to Australian international format (possibly native in v19) and syncing phonebook/call logs with our VOIP provider. • A pricing module with editable retail price lists for two zones (wholesale = retail – 10%),...

I need a polished, corporate-style portfolio site that reflects a professional, trustworthy image. The layout must be fully responsive so it looks and works perfectly on phones, tablets, and desktops. My priority section is a clear “Services” area that quickly explains what I do and why prospective clients should engage me; if you see opportunities to weave in an About page or a simple contact form later, keep the structure flexible enough to allow for that growth. Clean HTML5, modern CSS (Flexbox/Grid, media queries), and vanilla JavaScript for any interactive touches are all that is required—no heavy frameworks unless you can justify the benefit. Page speed and accessibility matter: Lighthouse scores should stay firmly in the green, and navigation must be intuitive. I ...
