      Web Development Review from Tifiny Swedensky

      Agency Partner built us a pretty website... but it was slow and not technically optimized for SEO. The backend was very buggy, with many "useless" sections in the WordPress dashboard. I am a WordPress developer, but I am also the company's marketing director so we chose to have the site developed by an outside company. I spent approximately 20 hours working on the backend removing useless "features" and optimizing the site to pass the Core Web Vitals. It should've been a huge red flag when the company wouldn't show us the backend before launch. Additionally, when they launched the site they "no-indexed" the entire website! Recently, I sent a ticket to support to fix 404 pages. After getting no response for several days, I went into the site and fixed the error myself. They had the audacity to send me a "we fixed the error" email 24 hours after we fixed the issues ourselves! If you are looking for a well-built site, look elsewhere. This company is only good for pretty site that loads slow and is bogged down with junk. The company reached out and heard my complaints. There's not a lot they can do to make this right (since most of the work they left undone was finished by me), but at least they listened. They extended our site warranty to help fix any outstanding issues. I'm adjusting my rating to three-stars.

      Logo Design Review from Alex Adamez

      Great service, fast and friendly. They were referred to me by a business colleague. I used their graphic design service to do my logo. I had a design that I created and wanted them to replicate. They also provided several other options for me to consider & compare. The turn-around time for them to complete was fast, just a couple of days. Will definitely have them assist on my web page

Their team is proactive, creative, and genuinely understands how to drive engagement and conversions. They’ve helped streamline my campaigns, improve content strategy, and get my brand in front of the right audience. Communication is always clear and responsive, and I feel like they truly care about my business’s success. Highly recommend OBCIDO to any business owner looking to take their digital presence to the next level! Thank you

      I had a great experience working with the OBCIDO team. Communication was clear from the beginning and their services were explained well beforehand, so I knew exactly what was offered. They stuck all deadlines and responded promptly to any emails or questions. Their selected writer/editor - Amr - who worked with me throughout the PR process, was the great selection by OBCIDO for my work with them. I would be happy to recommend them to more colleagues and artists in my community.

      Coretech has been an extremely valuable partner for the last 6 years. We started by re-writing our entire web application at the time - they were on-time, on-budget, and had a very strong team to help with the implementation. Since then we continue to use them as an extension of our team for enhancements, new features, bug fixes and the rest. Their wisdom and understanding of choosing the right approach and technologies has been invaluable. Honestly can't speak highly enough about the team, thank you Gil and team!

      Risa Hubble's Review Sourced from Google

      The team at Coretechs is phenomenal. We needed to transition our custom app and databases to a new developer rather quickly due to an unexpected discontinuation of service. Coretechs handled all of the details and made the transition absolutely seamless. They communicated their progress and timelines the entire time. Since then I've had them do some modifications to our app, which they turned around right away. Everyone I've talked to there is super friendly and super knowledgeable. I'm looking forward to working with them on future improvements.

      Recuiter Rashi Sahu connected me over Linkedin for job opportunity. Online Interview was scheduled for next day. I kept waiting at scheduled time for interview nobody showed up, after 15-20mins i pinged the recuiter over linkedin for which she replied that within next 15 mins they will connect me( i did smell the unprofessionalism). After 15 min online interview started. Interviewer asked about my profile and general questions.( No technical questions). And said they will inform me for next round. After 2 days or so i tried connecting recuiter, as expected no response. I did send email to share the feedback of first round of discussion, again- no response. I am not complaining as i have experienced such unprofessional attitude with recruiter earlier as well in other organisations. So this is just a kind request to all HR teams/recuiters. For you person is just a candidate who may or may not be a perfect fit for your requirement, but for a candidate you are a actual 'HUMAN' resource from whom he expects humble genuine response as your response/feedback helps him to improve and fine tune his upcoming career. Again I am requesting to share my proper feedback. (Eg. if have not cleared the first round, where i am lagging, what area i need to improve? Or whatever is the status). Thanks Prithviraj Soni
