Chop Dawg Reviews & Testimonials

Web Development Review from Jimmy Caldwell
Chop Dawg was the strongest development team I’ve worked with in 18 years of software implementation. They took our complex AI-powered senior placement platform and turned it into a functional marketplace with dashboards, business rules, CRM integration, and an AI assistant. The team listened, adapted, communicated often, and treated our vision with real care. The handoff had a few gaps, but overall, they delivered exceptional work.

Design Services Review from Nathan May
Chop Dawg delivered wireframes, high-fidelity screens, a logo, and Figma files while keeping each week’s work clear. They felt like part of our team, brought fresh ideas, and pushed back when needed. The experience was strong overall, though a more detailed final review would have been helpful.

Web Design Review from Anonymous
Chop Dawg turned our early idea for a visual polling and decision-making platform into a prototype we could confidently share with others. It made the product much easier to explain, gave us something real to test with users, and supported more productive investor conversations. The work also helped our team get aligned on the product direction, development scope, and MVP roadmap. Their team was responsive, organized, and easy to work with throughout the process.

ELEK+RIK Reviews & Testimonials

Web Development Review from Philip Wilson
ELEK+RIK team provided a streamlined process that was both simple and enjoyable. They kept to the budget and communicated well throughout the project. ELEK+RIK comes highly recommended and we would work with ELEK+RIK again if given the opportunity.

Mobile App Development Review from George McKerrow
ELEK+RIK has worked on improving our React Native mobile app. We had the skeleton of an app, but they were able to do an end-to-end re-design of each of the main pages. Since then, they`ve successfully implemented around ~20 different features on our mobile app. We share a spec and design, they provide an estimate and occasionally some design options, then when completed create a PR on GitHub. Their code is well-organized, easy to follow, and rarely do we have to go back-and-forth about bugs. They are also excellent communicators - carefully following threads on Slack, effectively communicating design and engineering tradeoffs, and even producing a 10m Loom video walking through a diagram. Their communication is top-notch. They are super easy to work with even though we are on very different time zones. And, I am impressed at the speed and execution of their development.

Web Development Review from John Riley
ELEK+RIK was tasked with creating a website for our company from scratch. They were professional, communicative, and dedicated to delivering an exceptional website that perfectly captured the essence of our company while exceeding our expectations. They are a talented, reliable, and customer-focused web design and development company that I would highly recommend to anyone.

Sigma Software Reviews & Testimonials

Software Development Review from Nikita Vershinin
We've partnered with Sigma Software for almost three years, and they proved to be a strong partner with whom we'll keep working. Their adaptability and willingness to get things done are unique, settingthem apart from other providers. Moreover, they demonstrate a strong sense of ownership.

Software Development Review from Michael Meyer
We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

Mobile App Development Review from Esther Howard
The client is incredibly happy with Sigma's services and work. It has referred 3 other clients who also say how much they really love the team and process to get set up with the agency. Sigma is a fantastic company with excellent experienced professionals. Its experts care about quality and customer satisfaction, and they operate like the internal team's extension.

AutomateNexus Reviews & Testimonials

Small Businesses Website Development Review from Jarrell A. Green, MBA-DA
AutomateNexus built our entire e-commerce website for KourtLit from scratch. We sell portable pickleball court LED projectors and needed a professional storefront that could handle orders, inventory, and customer communication.They delivered a modern, mobile-friendly site with a smooth checkout flow, backend database for order and inventory management, and automated email sequences for order confirmations, shipping updates, and follow-ups. They also set up our SEO foundation so we're positioned to rank for product searches.What stood out was their BYOK approach we own everything they built. No recurring platform fees, no vendor lock-in. They finished the entire project in July 2025 and handed it off with full documentation and training.If you need an e-commerce site built fast and built right, these are the people to call.

AI Development Review from Arionne Patterson M.S.
We hired AutomateNexus to build a new website for our boutique travel agency, and they delivered far more than we expected. Erin and the team built us a custom website, client portal, and admin dashboard from scratch plus set up automations that completely changed how we run the business.Before working with them, we were drowning in manual tasks: sending confirmations, chasing documents, following up with leads. Now most of that runs automatically. The client portal lets our travelers access their itineraries and documents anytime, and the admin backend makes managing bookings so much easier.What impressed us most was the strategic thinking. They didn't just build what we asked for they helped us rethink our entire workflow and showed us where AI and automation could save us time. We're saving 15-20 hours a week on admin work we used to do manually.Communication was excellent throughout, delivery was on time, and the final product exceeded expectations. If you're a small business looking to modernize your operations without getting locked into expensive monthly software, I highly recommend AutomateNexus.
