Inline Blue is a 2–10 person consultancy founded in 2020 that pairs staff augmentation and recruitment services with in-house product work. The stack (C#, .NET, Spring Boot, React, Docker, GCP/AWS/Azure) reflects a polyglot consulting practice; active hiring is weighted toward senior and lead engineers (6 senior, 2 lead, 3 mid across 10 engineering roles), signaling a shift from pure body-shop model toward owned product delivery — evidenced by projects including a greenfield product and an AI-driven content platform alongside e-commerce feature work.
