What I'm looking for

I'm looking to build practical AI-powered web products, especially SaaS platforms using LLMs, RAG, semantic search, analytics, and scalable full-stack architectures.

I'm building AI-powered recruitment workflows at Capgemini Engineering, including an Applicant Tracking System with semantic CV-to-job matching, OCR resume processing, candidate scoring, and natural-language analytics.

I use Next.js, React, TypeScript, FastAPI, PostgreSQL, pgvector, and RAG workflows to deliver type-safe SaaS products with role-based dashboards and practical AI features.

Previously, I built job-matching products for Aquil’App and conversion-focused AI-enabled experiences for Storegen.ai. At Aquil’App, SSR and code splitting increased user engagement by 60% and reduced time-to-hire by over 40%.

My work also includes internal analytics tooling, investment platforms, workflow automation, and projects such as PharmAI, Entretien AI, ClearSprint AI, AltScore AI, and FlowMatic.
