Testimonials and recommendations from engineering leads, directors, and principal architects I've collaborated with over my career.

  • Principal Software Engineer at Acquia
    January 13, 2026
    Krishna is an exceptional engineer who thrives in dynamic, fast-paced environments. Having worked with him since 2021, I’ve seen firsthand how adaptable he is when project requirements shift or new technologies emerge. He is particularly skilled in the Drupal ecosystem; I’ve been impressed by his ability to develop custom Drupal modules that are not only functional but architecturally sound. He brings a high level of discipline to his workflow, consistently ensuring code quality through thorough unit testing. This commitment to reliability, combined with his strong frontend skills, makes him a rare 'full-package' engineer. Krishna approaches every challenge with a 'can-do' attitude and a dedication to excellence that has been vital to our team’s success.
  • Technical Lead | GoLang, Docker, Kubernetes

    I had the pleasure of working with Krishna Singh on multiple projects, including a complex Personalization initiative, and he consistently impressed me with his versatility and execution quality. Despite having no prior experience with Ember.js, Krishna ramped up extremely quickly and delivered high quality, production ready UI components. His strong fundamentals in frontend engineering and deep familiarity with modern UI libraries allowed him to adapt fast and contribute meaningfully from early stages of the project. In addition to frontend work, Krishna is an excellent Drupal developer, with proven experience building enterprise grade plugins that are robust, scalable, and well-architected. His backend background in PHP gives him a solid full-stack mindset, which reflects in the quality and maintainability of his solutions. What truly sets Krishna apart is his clear communication, structured thinking, and collaborative attitude. He is reliable, easy to work with, and always focused on delivering real value. Any team would be lucky to have him, and I’d happily work with him again.
  • Senior Director, Web and Digital Development at U.S. Green Building Council

    Krishna started as an intern on my team and soon became an integral part of the team. I've had the pleasure of working with him for about 5 years on countless projects ranging from new website/platform launches and development of interactive online tools to ongoing support and improvements projects. He is wonderful, dependability, always available, and continues to excel in all aspects of work and life. I would reach out to him (a lot of times during off-hours) with tough issues and I always received a friendly response and a quick and solid solution. A fun team member who always believed in sharing knowledge and mentoring new team members. Krishna would be an amazing asset to any team in any capacity!!
  • Strategic Implementation & Workforce Development

    Krishna and I worked together at USGBC, where he helped continuously improve the Learning Lab online education platform for K12 teachers. He was very dedicated to the platform - coming up with new ideas for how to implement requested features and functionality, and working tirelessly to ensure we had solutions that worked for the customer. Additionally, Krishna is friendly, open to hearing feedback and pays great attention to detail.
