**Project Overview:** I am looking for an expert developer to build a lightweight desktop stock ticker application (Windows/macOS preferred) where the MAIN focus is high-utility, fully customizable AUDIBLE alerts. I want to monitor the markets by ear without constantly staring at my screen. The app will feature a customizable "Quote Builder" layout running on fast user-defined refresh loops, but the sound engine is the absolute priority of this project. **Core Audio Requirements (The Main Point):** * Event-Driven Sound Profiles: I need to assign distinct, custom text-to-speech (TTS) speeds, pitches, or triggers based on user-defined price movements. * Directional Audio Logic: Distinctly different tone pitches or speech profiles for "Up" ticks versus "Down" ticks so I can instantly hear market direction. * Speech Profiles: A drop-down menu to toggle between "Standard Mode" (reads full labels: "Tesla 100, up 2, bid 99...") and "Pro Mode" (strips all labels for high-speed tracking: "TSLA, 100, up 2, 99..."). * Global Panic Mute: Hitting the Spacebar or a dedicated hotkey must instantly mute/unmute all active audio feedback immediately. * API Key Settings & Data Feeds: The app must use a "Bring Your Own Data Feed" architecture. It must feature a configuration settings screen where users input their personal, API credentials (keys and tokens) to feed data into the ticker. * Brokerage Dropdown Selector: The UI must include a simple drop-down menu allowing users to choose which data provider or brokerage connection to activate (e.g., [Dropdown: Alpaca Markets, Polygon.io, Interactive Brokers, Yahoo Finance]). The developer must build modular data adapters for these connections. **Data & Interface Requirements:** * Custom Quote Builder: Ability to save layout templates choosing from fields like Symbol, Last Price, Up/Down, Bid/Ask Size, Day High/Low, Open, and Close. * Fast Polling Loops: Drop-down selector for data intervals per ticker: 1 second, 5 seconds, 30 seconds, 1 minute, or 5 minutes. * Multi-Monitor Support: Global hotkeys to switch saved templates instantly without needing the app window to be in active focus. * Ticker Looping: Supports inputting a single ticker or a comma-separated list to cycle through multiple stocks on the interval loop. **Budget & Contract Setup:** * Contract Type: Fixed-Price * Total Project Budget: $3,000 (To be broken into milestones upon signing an NDA) ⚠️ CRITICAL: You must start the very first word of your cover letter/proposal with the word "TICKER" to prove you are a human and not an automated bot. If your proposal does not start with the word "TICKER", it will be instantly declined without review. Please reply by explaining your experience with asynchronous programming, audio-based desktop systems, or handling high-speed financial APIs (like Alpaca or Polygon.io). Selected candidates will be asked to sign an NDA before receiving the full requirements document.

Looking for an expert that can help with this one time project.

I'm looking for an experienced Python developer who is familiar with: - Hugging Face's Diffusers and Transformers Libraries - PyTorch - Hosting model inference efficiently You also have to be okay with adult media (NSFW). I'm building a platform to host inference for AI models, particular image and video generation models, and some traditional LLMs / VLMs as well. We're currently using HF Diffusers and Transformers, although I'm open to using other runtimes. We're also building a python-library for our platform. Most of the code has been written by AI (Claude Code and Codex), and needs to be audited and improved / refactoed. The inference is way slower than I think it should be, so I'd like someone to take a look and recommend ways to speed it up; I'm down for any ideas you have really. When posting, please explain concisely why you think you'd be a good fit for this role. For example, 'at company Y, I built X, getting inference time down from 10s to 2s'. Any templated or LLM applications will be rejected immediately. A few sentences is long enough. Thanks and good luck.

Sunstone Systems is a managed platform business that builds data infrastructure and custom applications for operations-heavy clients. We are looking for a versatile implementation partner to take on fixed-price projects across our delivery pipeline. Start with a smaller paid task to confirm fit; ongoing work follows for the right person. The Stack - n8n (self-hosted) for workflow automation - Supabase / PostgreSQL - Next.js (App Router, TypeScript, tRPC) - Python for scripting, data work, and AI agent builds - AI agent development with Claude Agent SDK, MCP servers, and tool use patterns - Integrations work across APIs like Salesforce, Slack, ClickUp, and various SaaS platforms You don't need to be an expert in every line item, but you should be genuinely strong in at least three and comfortable in the rest. What You'd Actually Do Projects vary, but typical work includes: - Building n8n workflows that move data between client systems and Supabase - Working within new and existing Postgres / Supabase databases. Comfortable reading schemas, writing queries, and debugging triggers, functions, and RLS policies. - Writing Next.js features against an existing codebase - Building Python services and AI agents that integrate with the rest of the stack - Debugging production issues across the stack What I Need From You Operational thinking. Real experience with business workflows, SOPs, and processes, not just code. You understand that the system has to fit how the business actually runs. Resourcefulness above all else. When you hit something you don't understand, you dig. You read the docs, trace the code, build a small reproduction, and figure it out. This is the trait that I look for above any technical skill. Strong written communication and the ability to update a project within a PM tool. Comfortable working from a written spec and pushing back when something's wrong. Git discipline. Clean commits, sensible PRs. Logistics Fixed-price per project. Budgets vary by scope, typically defined in a short SOW before kickoff Start with one smaller paid task ($500 to $1,500 range) to confirm fit before larger work. Open to a long-term engagement for the right person. To Apply Skip the generic cover letter. Instead, tell me: One project from your portfolio that's closest to this stack, with a one-paragraph description of what you actually built. Your honest strengths and weaknesses across the stack listed above. A link to code you've written (GitHub, a gist, simple file share, anything real is fine). A short example of a time you hit a wall on a project and how you got past it. One paragraph is fine. I read every application personally. Applications without those four things won't get a response.
