Editorial responsibility
Owner and operator of FlawCheck, responsible for editorial direction, decisions, publication approval, and corrections.
FlawCheck Editorial Desk is the publication’s collective byline. Leo’s role as owner does not automatically make him the writer or reviewer of every article. Individual claim reviews are recorded in each article’s Flaw Intelligence panel.
Professional background
- Computer hardware engineering
- Banking IT
- Technology retail experience at FPT Shop and Mobile World
How I research products
- Use products in practice when available, then compare their strengths, limitations, and suitability for different buyers.
- Distinguish personal use from source-based research. Each article must state whether the specific product was used or tested.
- Approve editorial decisions within the documented evidence and keep unresolved questions visible.
Product experience is stated article by article
A professional background or a publication approval is not evidence that a particular product was tested. The FOSSiBOT F113 buying analysis, for example, explicitly states that FlawCheck has not used or tested the phone.
