Useful before an investment, a handover or a migration. - ### Fractional CTO A few days a month of senior technical leadership, from hiring and onboarding developers to reviewing their work, choosing tools and keeping the roadmap realistic. [Hire Me](https://liviu.dev/hire-me) ## **Consulting engagements** Each one starts with a short call and ends with a written plan you can act on, with me or with your own team. [
