Clients I Helped

Companies and startups I've collaborated with

Companies and startups I've collaborated with to build AI solutions, ship features, and solve complex technical challenges.

Constructed and maintained their RAG system and solved complex problems including a custom PDF chunking engine. Served as customer support, shipped features fast, and improved their chatbot solution by 63% by fixing their ingestion system. Part of the AI team constructing their new "Better OffBoarding", using agentic AI to interview a leaving employee to gather feedback and insights on their experience, creating a digital replica of the worker to answer questions on their role.

Built Vantiq, an SEO automation Agentic AI tool tailored to their needs: fetching SEO data on a brand, processing it into clusters of product categories of interest, generating AI insights on trends and actionable recommendations, plus AI-powered seasonality forecasts and market predictions. Among the coolest features, there is semantic expansion, that way the user can understand how AI models expand the brand's name when it is inputted. By automating the entire AI SEO evaluation process, Vantiq freed up the time the team previously dedicated to it, letting them focus on acting on the insights instead.

Curated the fullstack approach of the Sella financial institution, improving CI bug discovery by around 200%. Added crucial unit testing and E2E testing for their workflows. Migrated their Vue.js frontend to an updated version and removed all vulnerabilities along the way. Also maintained and curated their Java backend and their deployment processes, keeping delivery smooth and the platform secure. Coordinated and contributed to two of their projects, SalvaCarta and GoCreditPlus.

AI & ML

Models and intelligent systems

Models, experiments, and intelligent systems built for tasks like classification, generation, and optimization.

  • Predicting future video frames to enhance and interpolate low-frame-rate video streams. The task involved using LSTM architectures with squeeze-and-excitation modules to enhance performances.
  • First automatic translator and restorer for ancient Greek Linear B texts using multiple smaller models. Final translation is done by asking Gemini LLM to pick best reconstruction among options.
  • Research project on optimizing client selection in Federated Learning using Weighted Local Rademacher Complexity and other statistical learning tools.
  • Implemented Q-Learning, DQN, and DoubleDQN in Atari environments for comparison of performance and sample efficiency.

Full-Stack Development & DevOps

Products, APIs, and delivery systems

Web apps, APIs, cloud integrations, and deployment pipelines using modern tools and frameworks.

  • Blogging website about music built in PHP. Features include comments, likes, trending posts, and user ranking.
  • Ruby on Rails tourism platform with messaging, maps, Stripe integration, ratings, and personalized accounts.
  • Microservice-based AI feedback system with login, database, inference API, ELK stack, and monitoring tools.
  • This personal portfolio built with Jekyll, HTML/CSS, and fully responsive Apple-style UI.

Data Engineering

Pipelines, stores, and analytics

Data pipelines, transformation jobs, and analytics projects focused on performance and scalability.
