I’m midway through a personal project and need a seasoned Python mind to guide me from solid intermediate skills to confident, production-ready code. I’m looking for help that spans the full spectrum: refining my grasp of core syntax, strengthening advanced design patterns and optimisation techniques, and making better use of popular libraries and frameworks that fit the project’s needs. Here’s what I have in mind: • Regular, live coaching sessions where we review my code, untangle issues, and discuss best practices. • Clear homework or mini–milestones so I can apply what we cover right away. • Practical walkthroughs of any libraries we decide to incorporate, plus advice on structuring the overall solution. The end goal is to ship this pro...

I need a skilled React developer to jump into my existing code-base and complete a new feature from concept to merge-ready pull request. The exact area—whether state management, hooks, or a UI component—will be clarified as soon as you come aboard, but you should be comfortable working across a typical modern stack that includes React 18, functional components, and JSX/TSX. Here’s how I picture the collaboration: • First, you review the current repository, ask any clarifying questions, and outline a concise plan for the feature. • Next, you implement the solution in clean, well-commented code, following our linting rules and component structure. • Finally, you supply a PR with passing unit tests and a short hand-off note so I can verify, merge, and de...

This is a steady engagement structured around a monthly retainer of roughly $1,200. I’ll supply release note...

Contest: Build the Best Version of Stegstr () We are running a development contest to produce the best working version of Stegstr, the FOSS steganography application (reference site: ). We will open and test submissions ourselves, and award the prize to the single best-performing version. Stegstr is a nostr app. What we want built: - AI Agent Operability - Networking operations and functionality — a solid, reliable networking layer for sending, receiving, and syncing steganographically-encoded content between users. - Steganographic invisibility — the hidden data must be undetectable through normal viewing or casual inspection of the carrier file (image, audio, or other media). - Robustness to real-world processing — the hidden data must survive being sent through com...

I need a robust desktop application that mirrors PlanSwift’s core strength—fast, accurate on-screen takeoffs paired with instant cost calculations—while running natively on both Windows and Mac. Core scope • Upload architectural drawings in PDF, TIFF, or common CAD formats. • Let users set the plan scale, then measure counts, linear runs, areas, and volumes with click-and-drag tools. • Each measured item should drop straight into an estimating worksheet where labour, material, and markup values can be edited on the fly. • Calculations must refresh in real time, and the finished estimate should export cleanly to Excel or CSV. User experience I’m after a professional, detail-rich interface: dockable panels, layered plan view, colour...

I need a well-structured technical specification that zeroes in on performance metrics. The subject matter itself is already defined; what’s missing is a clear, formal document that captures how the system behaves under load, the quantitative targets it must meet, and the exact methods we will use to measure success. Think of it as the authoritative reference my development and QA teams will rely on when validating speed, throughput, latency, and resource usage. Here’s what I’m expecting: • A concise introduction that situates the system or component in its broader architecture. • A dedicated section for each key metric—definition, target value or range, calculation method, and testing approach. • Any formulas, data sampling intervals, and tool...

Our hiring pipeline is filling up with senior-level mainframe candidates and I need the interviews handled by someone who speaks their language. The sole purpose of these sessions is to validate deep technical skill—no culture chats or HR-style screenings—so each call must drill straight into COBOL programming, JCL mastery and hands-on DB2 management. Here is what I need from you: • Craft a concise yet challenging question set that uncovers real‐world competence in those three areas. • Run remote, one-on-one video interviews (I’ll schedule them) and keep them within a 45-minute window. • Score every candidate against clear criteria and deliver a brief written report summarising strengths, gaps and overall hire/no-hire advice within 24 hours of each c...

I need a desktop-based tool that can speak the native, proprietary languages of three different DCS families—ABB 800xA, ABB AC450 and Mitsubishi DIASYS Netmation—and then use those links to send remote-control commands. The scope centres on building (or integrating) protocol drivers for each system, proving that they can log on, browse the tag database, write set-points and issue start/stop or mode-change commands exactly as an operator console would. Once the drivers are stable, they have to be wrapped in a single Windows desktop application with a clean UI where I can select the target DCS, pick a tag, send a command and view a confirmation/echo. Acceptance is straightforward: if the test script can alter a value or state on each DCS and the change is visible on the native ...

I want to build a full-stack desktop application that enables pharmacists in my store to manage daily operations from a single, intuitive interface. The core modules I need are: • Inventory management that keeps real-time stock levels, tracks expiry dates, and provides low-stock alerts. • Prescription handling with quick patient lookup, doctor information capture, and automated interaction checks. • Sales reporting that summarises daily and monthly revenue, highlights best-selling medicines, and exports to CSV or PDF. The entire workflow—from receiving a prescription to final sale—has to feel seamless on a desktop computer, so performance and an offline-friendly architecture are important. A clean UI/UX, role-based access, and straightforward installation o...

I need a self-contained Windows application that can handle end-to-end payouts through Indian banking rails—specifically IMPS and NEFT, nothing else. The tool must run locally on a Windows machine without relying on any existing ERP or web platform; everything from beneficiary management to transaction initiation and status tracking should sit inside this standalone executable. Core flow I have in mind: • Secure login for authorised staff. • Simple screens to add or import beneficiaries, store IFSC and account details, and mark KYC status. • Batch or single-click payout execution over IMPS or NEFT, selecting the rail automatically by cut-off time or allowing a manual toggle. • Real-time or near real-time acknowledgement retrieval and a clear ledger/history pa...

We're hiring a part-time sourcer to find and pre-screen US-based software developers for us. This is an ongoing, long-term role — not a one-off project. How this works: You handle the first stage. You find candidates, reach out, and run a short screening call to filter out anyone who isn't a fit. You then hand us a shortlist. Our team runs the technical interviews and makes the hiring decisions. You are not responsible for closing hires — your job is to make sure that by the time a candidate reaches us, they're worth our time. Budget: $300–600 USD/month, paid bi-weekly or monthly. Final rate depends on experience and weekly hours. We're open to raising this over time based on results. What you'll do - Source US-based developers via LinkedIn an...
