What I'm looking for

I’m looking for a remote-first team where I can ship production LLM features, refine prompts with rigorous evaluation, and automate workflows—while ensuring outputs are accurate, safe, and aligned with human intent.

I’m a software engineer and co-founder of KeeBoost SARL, with 4+ years of hands-on experience building AI-powered products and automating business workflows. I work daily with large language models, bringing a practitioner’s focus on how models behave in the real world.

At KeeBoost, I architected and shipped two commercial SaaS products—KeeMatch (ERP for SMEs) and Dossy Pro (AI-powered legal document management). I integrated LLM APIs (Claude and GPT-4) to deliver drafting, summarizing, and real-time legal document flagging, while iterating on prompts to improve factual accuracy and tone consistency.

I design evaluation processes using custom rubrics for helpfulness, factual correctness, safety, and format compliance—directly aligned with RLHF-style annotation needs. I also lead AI automation workflows with n8n (e.g., email routing, CRM updates, invoice generation, and WhatsApp notifications) and manage quality standards while leading a team of 3 developers.

Beyond product delivery, I freelance as an AI automation consultant—building chatbot assistants, testing prompt templates with edge cases and adversarial inputs, and running AI literacy workshops. I also conduct personal LLM evaluation and red teaming across domains to document failure patterns (hallucinations, context drift, refusal over-triggering) and improve mitigation strategies.
