When providing software development services for startups, we adopt a highly personalized approach. We take into account the type of product being developed, the speed of feature output and the expected date of release to the market.
Also, when developing a startup, you need a Tech/Team lead who will be involved in all parts of the software being developed. This is a team member who sets goals, monitors progress, and understands both the front-end and back-end sides.
Then we form a team, depending on the budget and needs, adding BackEnd, FrontEnd, DevOps specialists. When scaling a team, we must add PM and QA, most often part-time is involved in the initial stages of PM, QA, and DevOps.
