Essential Designs Reviews & Testimonials

Web Development Review from Chris Bailey
I engaged their web-development team to rebuild and modernize our company's manufacturing website, and the experience has been exceptional. From the outset, communication was clear and responsive: they took time to understand our industry-specific compliance needs and translated them into a site structure that is clean, secure, and easy to navigate. Delivery was on schedule, and the final result exceeded expectations pages load quickly, the design feels professional and trustworthy, and the content layout supports clarity for both clients and regulators.In addition, the team proactively suggested helpful enhancements: mobile optimization, streamlined navigation, and improved documentation pages all of which have already resulted in noticeably increased user engagement and lower bounce rates. They handled feedback promptly and implemented corrections without fuss, making the collaboration smooth and efficient.Overall, this project added significant value to our online presence, giving us a polished, modern website that accurately reflects our manufacturing standards and commitment to quality. I would gladly work with them again and recommend their services to anyone seeking reliable web development for regulated-industry clients.

Web Development Review from Kendall MacNabb
We needed to have a custom guest communication platform built, due to our custom workflows at the business, connecting our team members with text, images, buildings and daily project tasks. Essential Designs was able to hit the exact deadline we had, to the day, and completed on budget. We continue to add on features, it's a good relationship.

Aman Setia's Review Sourced from Google
The worst experience with the company. First they will call you and will ask you to go for 2 hours exam just like a half yearly or annual exam conducted during school time. After that they will ask you to wait for long. The interviewer will come and will ask only about your past company to attain it's strategies to move ahead and then they will ask you to go as we have a negative results regarding you. They will make you feel comfortable as if you will be selected and then the interviewer himself will be unsecured after seeing your profile, aa you are going to be a threat to them. As of now, they are not having any urgent requirements but calling you to waste your precious time only. Prefer not to go for an interview over here.
Abhishek Bhatia's Review Sourced from Google
Squareboat has been a special part of my journey as a Mobile Engineer for the past 2 years (and counting). What truly makes it a great place to work is the people. You’re surrounded by incredibly smart driven individuals. That’s what makes showing up to work every day genuinely enjoyable.From collaborating on diverse, challenging projects to learning from peers across different teams, the experience has been both rewarding and memorable. The culture is relaxed yet focused, and there’s always room to grow, explore, and contribute meaningfully. Highly recommend it for anyone looking to join a solid tech team!
Tushar's Review Sourced from Google
Experience at Square Boat has been awesome! I've felt super welcome from day one. Even though I'm just an intern, I feel like my input matters and I've had chances to develop skills I didn't anticipate.I'm early in my professional journey, but working at Square Boat has given me a real glimpse of what quality service actually looks like. The dedication to clients is genuinely inspiring.
