Critical Mission Computing were excellent in designing a website for my new business. They listened to my needs and were happy and available to make any changes I requested and to offer advice and answer questions. Alka Bagga was great at communication and keeping in contact during the process. Having gone live, she has been in contact to see how my website is going and to add more value. I highly recommend the company.

Alka and her team at Critical Mission Computing Ltd designed my new website www.rikachandra.com, and I am really pleased with the final result. 💓Have a look and see what you think!😉 Alka took the time to understand my style and preferences and helped me choose the most suitable template. The team also carried out their full research and discovery process (including keyword work for content) and handled the complete website optimisation with Google My Business. It’s a service I’d highly recommend to any SMEs looking to strengthen their online presence. 👍🏾

A huge thanks to Alka Baga and her brilliant team at Critical Mission Computing for their swift, seamless, and—dare I say—stress-free setup of my landing page. From the word go, they were on it. Alka immediately understood what I needed and ensured every detail was spot on.
Charmaine Dawkins-AlderDifference A Day Makes
After a disappointing experience with another SEO company, we were extremely lucky to find CMC. I have been dealing personally with Alka who has been very supportive and helpful with any concerns I may have. She is always prompt and punctual with all communication and briefs us on the status of the site on a regular basis, providing insightful advice on SEO. Its early days but she has worked hard to increase our online visibility and at a reasonably cost – I am confident this will show a great return on our investment. I would definitely recommend CMC to friends and family but not our competitors 😉
