Радуюсь, видя, какая команда получилась.Готовность обеих сторон к разговору и движение навстречу оставили положительное впечатление. В процессе работы очень помогали артефакты первоначальных договорённостей. Результат получили отличный! Хорошо, что договорились о работе в офисе Gems: это бустануло команду за счёт взаимодействия с нашими сотрудниками.
Уже уже несколько лет мы сотрудничаем с командой Effective для разработки нашего бэкенд-сервера, фронтенд-панели управления и мобильных приложений для iOS и Android. На протяжении всего партнёрства они неизменно демонстрируют высокий уровень профессионализма, ответственности и технической экспертизы. Их коммуникация чёткая и прозрачная, и они всегда оперативно реагируют на наши запросы и сроки. Если вы ищете надёжного и опытного партнёра для разработки, я настоятельно рекомендую команду Effective.
В работе с Effective меня радуют три момента. Первый – это прозрачная и понятная коммуникация, второй – вовлечённость. Чувствуется, что ребята заинтересованы тем, что делают. Также хочу отметить готовность команды работать с изменениями: если в требованиях что-то меняется, то мы вместе думаем над решениями и следующими общими шагами.
Работаем с ООО «Красавчик» не первый год. Сотрудничеством довольны: разработчики, которых берём на наши проекты, хорошие, и они активно проявляют себя. Если говорить о закрытии вакансий, то партнёры оперативно предлагают кандидатов и в достаточном количестве.
За время работы над проектом разработчик от Effective всегда был на связи и чётко укладывался в сроки выполнения задач, а также оперативно и качественно решал срочные незапланированные задачи.
Баги исправлял ещё при первичном тестировании, проблемы на проде решал оперативно и качественно. Инициативен и самостоятелен, с ролью лида справляется хорошо.
There are three things I especially appreciate about working with Effective. First is clear and transparent communication, second is strong engagement. You can tell the team genuinely cares about what they do. I’d also highlight their flexibility — when requirements change, we work together to find solutions and define the next steps.
We’ve worked with the Effective team for several years on the development of our backend server, frontend dashboard, and mobile apps for both iOS and Android. Throughout the partnership, they’ve consistently demonstrated a high level of professionalism, responsibility, and technical expertise. Their communication is clear and transparent, and they are always responsive to our needs and timelines. If you're looking for a reliable and skilled development partner, I highly recommend the Effective team.
I’m really pleased with how the team has come together. Both sides were open to communication and willing to meet halfway, which left a very positive impression. The initial agreements and documentation were very helpful throughout the process. We achieved an excellent result. It was also a great decision to work from the Gems office — it boosted the team through closer collaboration with our employees.
It’s easy and enjoyable to work with the Effective team. All tasks are delivered on time and at a high standard, even in a fast-paced environment. Communication is smooth, the team thinks ahead and finds solutions when challenges arise, and they quickly adapt when priorities shift. I’d especially highlight their strong sense of ownership and engagement. It truly feels like we’re working toward one shared goal, with everyone committed to delivering a high-quality result.
During the project, the Effective developer was always available, consistently met deadlines, and handled urgent, unplanned tasks quickly and efficiently. Many issues were resolved during initial testing, and any production problems were addressed promptly and with high quality. They showed strong initiative, worked independently, and performed excellently in a lead role.
We’ve been working with Effective for several years and are very satisfied with the collaboration. The developers we bring onto our projects are strong and proactive. When it comes to hiring, our partners provide candidates quickly and in sufficient numbers.
Over the years, we’ve delivered over a thousand projects across different technologies, industries, and markets
