About Us:
Briance is a fast-growing, tech-enabled luxury cleaning company based in Montreal. We specialize in recurring condo cleaning for busy professionals in the downtown core. Our operations are unique: cleaners travel mostly on foot, supported by a driver who delivers supplies and occasionally provides lifts. We’re now ready to optimize those routes using a custom algorithm.

Job Overview:
We are looking for a developer or operations research specialist with experience in route optimization using Google OR-Tools or similar frameworks. This is a one-time contract to build a functioning routing solver that optimizes our daily driver route, based on real-world bookings and constraints. If successful, this may lead to future projects.

Project Scope:
You will be building a route optimizer that takes into account:
- All real bookings for the day, with addresses and arrival windows
- Whether a lift is needed before and/or after each service
- Driver’s starting address
- Each cleaner’s starting address
- Whether storage access is required before or after the route
- Potential cleaner pickup locations (metro stations, intersections, storage)

Constraints to respect include:
- If there is a pickup after a service, it must occur no earlier than the end of the service (i.e., after the full duration)
- The solver can choose to include or exclude pickups based on efficiency
• All arrival windows must be respected
• The driver cannot be in two places at once
• Cleaners cannot arrive late to a job

Expected Output:
- A route plan for the driver, with all required pickups and drop-offs
- Exact times for each segment
- Downtime between stops
- Logic for whether the driver or the cleaner should initiate movement

Requirements:
- Experience with Google OR-Tools or similar optimization libraries
- Strong Python skills
- Understanding of vehicle routing problems, time windows, and custom constraints
- Ability to design and test a solution based on real-world data
- Ability to work independently and communicate clearly

Nice to Have:
- Experience with logistics or field service scheduling
- Ability to integrate with Google Sheets or Zapier
- Familiarity with mapping APIs (Google Maps, Mapbox, etc.)

Contract Terms:
- One-time project
- Flexible working hours
- Pay to be discussed and established based on project scope
- Potential for follow-up contracts if the collaboration goes well

CDK, & Helm charts, AWS, python coding, managing various backend tasks.

Project goal
I need a reproducible study that compares three portfolios (Golden Butterfly, an euro-tilted version, and one extra mix we will agree on).
Key metrics: safe-withdrawal rate (SWR), perpetual-withdrawal rate (PWR), drawdown depth and length, start-date sensitivity, and Monte-Carlo probability of ruin.

Scope and deliverables

1. Data pack
– Collect monthly total-return data from 1970 to 2024 in EUR.
– Provide a README listing every data source and ticker.

2. Back-test notebook (Python or R)
– Rebuild 50-year performance for each portfolio, with rolling stats, SDS, and heat maps.
– Notebook must run end-to-end in a clean environment (requirements.txt or renv).

3. Monte-Carlo module
– Run at least 10 000 paths, with stochastic inflation and EUR / USD drift.
– Produce SWR and PWR tables plus distribution charts.

4. Report and hand-off call
– 5-10-page PDF summarising results.
– One-hour Q&A call.
– Deliver all code and data in a private Git repository. I keep IP rights.

Budget and milestones (fixed price EUR 4 000)

Milestone 1 – Data audit and README – EUR 700
Milestone 2 – Back-test notebook – EUR 1 200
Milestone 3 – Monte-Carlo and withdrawal analysis – EUR 1 200
Milestone 4 – Final report and call – EUR 900

Required skills
• Python (pandas, NumPy, matplotlib) or R tidyverse
• Quantitative portfolio analytics, SWR modelling, Monte-Carlo simulation
• Clear documentation and version control (Git)

How I work
• I am in UTC+9 (Seoul). Async is fine, but I prefer a short weekly check-in.
• Communication via Slack or Toptal chat; video when useful.
• I am technical enough to run the code and read maths, so I need things to be transparent enough to allow me to sanity check and give feedback

We are developing a language-learning website where people can listen along to lyrics and see their translation. The application involves two main component: (1) a word/lyrics search, and (2) a audio/video Player. I've included two screenshots to give you an idea. The point of the project is to help millions of people around the world learn a new language in a fun way -- listening, singing, dancing, etc. We want to make language-learning fun. I've included two screenshots of the product.

Here are some technical details about it and what we're looking for in you:

- We want to find a developer who loves with this idea and wants to work on it. If you are looking for a high-paying gig, please do not bother here as it'll be a waste of your time.
- You should have experience with a front-end framework such as React (or Vue or Svelte), and have experience deploying a web-based project to iPhone/Android.
- You should also know backend -- preferred stack is python/mysql, but using node or postgres is also fine.
- We'll be using the following APIs: Algolia for search, Google Translate for translation, YouTube embed API for syncing the lyrics with the YouTube video (though we only want to 'show' the progress bar and controls...i.e., we only want to use it as "audio" and not a video.
- If you love doing things like reversing and tinkering around to make things work. For example, you'll be doing this with syncing the lyrics to the YouTube "audio". Note: one option is downloading the audio and using our own player. I think this might be against the YouTube TOS, and so for a product where we want to maximize reach, we don't want to do this.

Freelancer Project: Advanced Grafana Dashboard for Customer Usage & Balance Forecast

I'm looking for a freelancer to build an advanced Grafana dashboard for monitoring customer usage and their prepaid account balances. This project requires:

1. Usage Data Visualization & Prediction:

Data Source: An Elasticsearch index containing daily aggregated customer usage data. There is no need for data cleanup.

Aggregation Views: Create multiple widgets to display usage aggregated daily, weekly, and monthly.

Historical Charts: For each aggregation period, include a clear chart visualizing past usage data.

Future Trend Prediction: Integrate Machine Learning (ML) to extrapolate and predict near-future usage trends for each aggregation period.

2. Balance Burndown & Recharge Alert:

Credit Data Integration: Fetch the latest account top-up values from a separate "balance history" API.

Balance Depletion Chart: Create a "burndown" style chart that visualizes the rate at which prepaid account balances are depleting. This chart can either overlay the usage prediction or be a dedicated widget.

Zero Balance Forecast: The burndown chart must clearly indicate when in the future the available balance is predicted to reach zero, based on the forecasted usage.

Recharge Recommendation: Highlight a specific time range on the graph, suggesting recommended start and end dates for a new account top-up to prevent any service interruptions due to insufficient balance.

Overall Goal:

The dashboard should provide a comprehensive, proactive overview of customer usage, their balance depletion, and a crucial "call to action" window for account top-ups, ensuring uninterrupted service.

I am looking for a highly skilled full-stack developer (or small team) to help me transform my successful, custom-built Python trading bots (v4 and v5) into a multi-layered, professional web application.

The bots currently run inside the TradeLocker platform and perform very well — but I want to expand their power, control, and flexibility by building a dedicated web interface with backend automation and direct API integration into TradeLocker.

This will allow me to run both bots (Buy-side and Sell-side layers) independently, manage their parameters in real time, and automatically place pending orders inside TradeLocker via API calls — all from a custom-designed web dashboard.

Your contributions will directly impact our trading operations, so a keen attention to detail and problem-solving skills are essential. If you are passionate about trading technology and have the required skills, we’d love to hear from you!

I’m a practicing criminal defense attorney based in Florida, and I’m launching a new AI product called My Conference Call — an on-demand phone interpreter designed for professionals who work with clients who speak limited English.

The concept is simple:
A lawyer (or other professional) places a client call on hold, dials our AI interpreter number, merges the call, and gets real-time voice translation between English and Spanish.

I’m looking for a developer to help me build the MVP. • A Twilio voice number that can accept calls
• Ability to merge a 3-way call (client + user + interpreter)
• Real-time speech-to-text (using Whisper or Deepgram)
• Language translation (GPT-4o or similar)
• Text-to-speech to speak the translated result (Amazon Polly or Google TTS)
• Stream translated audio back into the call in real time

This project is ideal for someone who’s worked with Twilio Programmable Voice, real-time audio, or AI integrations. Python preferred, but open to Node.js.

Timeline and Budget - I’d like to launch a functional MVP within 3–4 weeks.

Estimated total budget: $4,000–$6,000, structured as follows:
1. Milestone 1 – Twilio Call Flow Setup:
Build basic call handling, conference merge logic → $1,000
2. Milestone 2 – AI Interpreter Integration:
Set up Whisper/Deepgram + GPT translation + TTS response → $2,000
3. Milestone 3 – Real-Time Streaming + Testing:
Live call testing, audio streaming polish, latency tuning → $2,000–$3,000

You’ll work directly with me — I have the brand, domain, and a pipeline of attorneys ready to use the product once it’s live.

To apply, please include:
• Your experience with Twilio and voice AI tools
• Relevant past projects
• When you’re available to start

Looking forward to working together.

• Describe a project where you used Twilio to manage voice or conference calls. What challenges did you face?

Please find enclosed document.
Please feel free to send questions. Please do not send generic cover letters. I need at least 2 examples of your python implementation with details of logic and workflow you created.
