I need a Lead Architect to own the technical design layer before the day starts and serve as the senior technical resource in the room on May 16. Before the day: you work with the Reviewer to validate each founder's submitted Build Plan, ensure every workflow is technically sound, and produce the final implementation guide the support team works from. On May 16: you are in the room as the most senior technical person. When a founder or a team member hits something complex that needs a judgment call — a tricky API, an unexpected edge case, a workflow that needs redesigning on the fly — you make the call. You are not running from founder to founder all day. You are t...

I’m working with voice AI agents (using Retell AI), and I want them to be able to book appointments directly into Google Calendar. The idea is pretty simple in my head: I want to create a small set of functions (like a toolbox) that the AI can call depending on what the user says. For example, if someone says “I want to book an appointment,” the agent should just call something like "create_event" and that handles everything in Google Calendar. So basically, I need you to build that layer in between — something clean and reusable. A few important things: First, I’d like around 6–10basic functions: create_event, check_availability, list_events, update_event, delete_event… that kind of stuff. Second, these functions need to be super ...
I’m building a full-featured web application and want it written entirely in PHP using the Laravel framework. The core idea, database structure, and UI wireframes are ready; what I need now is a developer who can translate that groundwork into clean, maintainable code, set up migrations, craft RESTful controllers, and integrate basic authentication and role permissions. Your role will cover everything from configuring the environment and routing to polishing Blade templates so the front-end feels snappy and modern. I value code quality over quick hacks, so sticking to Laravel best practices—service containers, Eloquent relationships, queued jobs when appropriate—will be key. Once the MVP is functional, I’ll handle user testing and feedback, but I’d like you t...
I want to turn a fresh idea into a polished desktop application I can sell and use to support my family. I’m starting from the ground up, so I need a developer who can guide me through the full lifecycle—defining a viable concept, choosing the best tech stack, coding, testing, and packaging the final installer. You’re free to work in a language you’re most comfortable with—whether that’s C#, Java, Python, Electron/JavaScript, or something comparable—as long as the result runs smoothly on Windows and can later be adapted for macOS or Linux if sales demand it. Robust error handling, an intuitive UI, and clean, well-commented code are must-haves so I can maintain or expand the product later. Deliverables • A brief proposal outlining two or th...
I need a custom Minecraft mod that lets me define a Y-level plus exact width, length, and height, then automatically excavates that regular cuboid space with pixel-perfect accuracy. Once the cavity is ready, the same mod must load a schematic file and erect it block-for-block, leaving any extra clearance I specify. The schematics I work with are enormous and intricate: dense redstone wiring, timed updates, fluids such as water and lava, signs, and other update-sensitive blocks. Accuracy is the absolute priority; a single misplaced repeater or water source breaks the entire build. I am fine if the process takes longer as long as every block ends up exactly where the schematic says. Key expectations • Player GUI • Automatic digging that respects the chosen boundaries and sto...

I have a set of annotated screenshots that capture every element of an existing TradingView strategy, but no source code. Your job is to translate those images into a clean, fully functioning Pine Script Strategy that behaves exactly like the original: same plots, same signals, same back-test results. You will receive the screenshots and a brief explanation of the intended logic as soon as we start. I expect: • A single .pinescript file written in Pine v5 • Settings, inputs and plots matching what appears on my charts • Comments in the code so I can follow the logic and tweak parameters later • A short note comparing your back-test metrics to the ones visible in my images to confirm the match Please send me a private message that includes at least one TradingVi...

I have a single player-movement script that already does the job, but the code has grown a bit unwieldy. I’d like an experienced Unity developer to open the file, streamline the structure, and tighten the logic while keeping behaviour identical in-game. My top priority is stronger error handling; where try/catch blocks or validation checks make sense, please add them. Please follow Unity’s C# coding standards throughout. Inline only the essential comments that clarify the changes you make—no need for line-by-line narration. If you notice any quick wins beyond basic cleanup, jot a short note so I understand the reasoning. Deliverables: • A revised .cs file that compiles and runs as before, now cleaner, safer, and easier to read • Brief notes (a few line...

I’m creating an Android-only application and need a developer who is equally comfortable in native Android (Java/Kotlin) and Python. The main objective is to connect a set of existing Python scripts to a clean, responsive Android front-end so the logic runs directly on the device. Here’s the current state: • All Python functionality is already written and tested on desktop. • No Android code exists yet; you will design the UI and wire it to the Python layer. • The bridge can be Chaquopy, Kivy, BeeWare, or any approach you prefer, provided performance on recent Android versions stays smooth. Scope of work 1. Set up the project structure and integrate the Python modules so they compile into the APK. 2. Build a minimal Android interface: a sin...
Saya sedang menyelesaikan tugas akademik C++ yang menuntut pembuatan program sederhana untuk pengolahan data. Intinya, saya butuh: • Satu contoh program lengkap (C++17 atau lebih baru) yang dapat membaca data dari file atau input standar, memprosesnya—misalnya menghitung statistik dasar atau mem-filter nilai—lalu menampilkan hasilnya dengan rapi. • Kode diberi komentar jelas baris-per-baris agar mudah saya pahami dan modifikasi. • Penjelasan singkat (README atau PDF) tentang struktur program, logika utama, serta cara menjalankannya di Windows dan Linux menggunakan g++/clang++. Saya tidak membutuhkan antarmuka grafis; cukup berbasis terminal. Silakan memakai library standar (STL) saja, tanpa dependensi eksternal agar kompilasi tetap sederhana. Kirimkan be...
I already have a fully packaged code-base for an existing tool and now I need a fresh Windows desktop application that mirrors its user-interface one-for-one. You will receive the current package, screenshots of every screen, and a short walkthrough video; your job is to translate that experience into a modern, maintainable Windows executable. The core logic is in place, so the assignment is almost entirely about recreating the UI: layouts, navigation flow, dialogs, and visual behaviour. Feel free to propose WinForms, WPF, Electron, or any other Windows-friendly framework you are comfortable with as long as the final result installs easily and runs smoothly on Windows 10 and 11. Good naming conventions, clear project structure, and concise in-line comments are essential because this cod...
I have a mature ActionScript project that still runs well feature-wise, but its performance is showing its age. Right now my only priority is to squeeze every possible millisecond out of it—no new features, no general bug hunting, just measurable speed gains. Two hot spots keep holding the app back: • Loading speed, specifically during the data-processing phase after assets have been fetched. • Graphics rendering, where complex vectors and filters spike the frame time. Your task is to profile the existing code, identify the worst offenders, and refactor or rewrite sections so the initial data crunch finishes promptly and the on-screen visuals remain smooth under load. I expect you to work with typical ActionScript tooling (Flash Builder, Scout, Adobe Animate or compar...

I maintain a growing web application written in both Rust and Go and I’m looking for a US-based native English speaker who can jump in confidently on the server side. The codebase relies on Rust’s Actix and Rocket frameworks alongside Go’s Gin router, so recent hands-on experience with all three is essential. Your first priorities will be twofold: shipping new user-facing features while also hunting down and patching the most visible bugs reported by our QA team. Performance tuning and architectural refactors are handled by another engineer, so your focus stays squarely on feature work and defect resolution. To make sure we stay aligned, here’s how I’ll review your work: • A concise pull request for each feature or fix, passing our existing CI tests. ...
