Expertise

Data Analysis

Data analysis on massive datasets, tailored to your application. Data really is key for any analysis and eventual deep learning model development. Let's focus on collecting, filtering and organizing data on a massive scale. This involves using object storage offerings from cloud providers to scale up and down the data stored effectively at reasonable costs. Recent LLMs advancements in efficiency also allow us to filter and organizing data at extreme accuracy, by having the machine "understand" the data. While still a rather expensive operation, this one-time cost of intelligence can really elevate the results.

Generative AI

Fast prototyping of RAG and data management systems to apply the latest advancements in AI to your specific niche. By working together, we can boost accuracy and usefulness of the best models in the world, and ensure reliability (practically zero hallucinations).

End-to-End Knowledge

Staying current across the entire technology stack is key. From identifying the best current hardware for price and performance, to selecting a Python version that works well with specific libraries and cuda drivers, right down to algorithmic optimizations, I maintain the full stack of practical and theoretical knowledge needed to deliver top results efficiently, considering cost, ease of deployment and speed of execution.

User-Facing Applications

Rapid prototyping of user-friendly applications. Expertise in Flutter for cross-platform mobile apps (Android & iOS) and web development using React and Flask, typically. Proficient in integrating databases, including SQLite for quick prototypes, and experienced in deploying robust production applications on Linux servers.

Projects

GPTprepay.com

Consumer-oriented website allowing anyone to use the current best models, without paying a subscription.

Market & Sentiment Analysis for Keyvian

Performed market and sentiment analysis for Keyvian, a startup incubated at Blaze (EPFL's startup incubator). The project involved scraping massive amounts of web data from 2013 to 2023 and comparing it to price movements in various crypto assets during that period.

Currently in the works:

  • LLMs for Swiss Legal Applications: Applying LLMs for legal applications, focusing on the swiss legal system.
  • Artisan Showcase Tool: A tool for artisans to showcase their creations, creating compelling marketing material (images and videos) with a single image of the product as input. Unprecedented accuracy is made possible by the latest breakthroughs in native image generation (auto-regressive models instead of diffusion models).
