The most responsive source of highly experienced senior software engineers

To Whom It May Concern,

I am pleased to write this letter of recommendation for Square Codex, with whom we had the pleasure of collaborating on a recent Salesforce initiative. Over the course of our partnership, Square Codex provided us with Salesforce Quality Assurance (QA) professionals who proved to be highly dependable, skilled, and collaborative.

From the outset, their team demonstrated a clear understanding of our needs. The QA resources they assigned were not only technically competent, but also proactive, detail-oriented, and committed to delivering high-quality results. Their structured and thoughtful approach to testing significantly contributed to the success of our project, ensuring a smooth delivery with minimal issues in production.

I would not hesitate to recommend Square Codex to any organization looking for top-tier Salesforce QA support. Their professionalism, resource quality, and commitment to excellence set them apart as a valuable partner in any Salesforce engagement.

Please feel free to contact me directly if you require any further information.

I’m happy to recommend Square Codex for their software engineering staff augmentation services. We’ve been working with a senior full stack software developer they placed on our team, and the experience has been excellent from the start.

The developer was able to contribute meaningful work from day one, quickly getting up to speed and adding value without much hand-holding. They’ve consistently taken initiative—researching, proposing, and implementing ideas independently—which has made a real difference in our projects.

Square Codex has been professional, responsive, and easy to work with. As a U.S.-based company, we’ve appreciated the opportunity to support a growing Latin American firm and help them establish a stronger presence with U.S. clients. It’s been a mutually beneficial partnership, and we’re looking forward to expanding our relationship moving forward.

I have worked with Square Codex for a number of years now and they have been great to work with. Very supportive when we need to make changes and very flexible as well. They have a great talent pool so when we need it they have someone for us. We highly recommend them.

I am pleased to recommend Alejandro Azuola and Square Codex for their exceptional staffing services. I have personally worked with Alejandro for over two years to fulfill our contractor needs.

Square Codex has consistently provided us with highly skilled nearshore Software Developer and Quality Assurance Engineers at competitive rates. Alejandro’s willingness to begin working on contractor needs before they are fully defined and to accommodate contracts under six months makes him more flexible than many other agencies. His prior experience as a software engineer also allows him to align candidates more precisely with our requirements. His turnaround time is remarkable, often presenting strong candidates within just 1-2 business days.

Beyond efficiency, Alejandro has earned our trust through his integrity and commitment to our best interests. A prime example of this was when we were prepared to issue a six-month contract, but he informed us that the resource was open to a shorter term—despite this meaning less revenue for him. This level of transparency is rare in the industry and has only reinforced our confidence in him as a partner.

Working with Square Codex and Alejandro Azuola has been a pleasure. The speed and quality of the engineers that Square Codex has provided have enabled us to cut months of time from our roadmap at a fraction of the price. And each of the engineers is just a member of the team working in similar time zones as ours. Interfacing directly with the owner means I’m not having to pay for project managers or sales people. It cuts my costs and I know I’m dealing with someone who cares. It’s a win-win situation. Any time I receive a cold call from someone trying to sell me near-shore services, I let them know that I am not interested as we have found our partner in Square Codex.

Square Codex provides very competent resources that produce excellent deliverables to the satisfaction of internal resources. They regularly communicate with us to ensure a smooth relationship and incorporate feedback into their interactions.

Square Codex produced final deliverables that exceeded internal stakeholders. They stand out for their decision-making process, and the team communicates effectively through email, Slack and Microsoft Team meetings.

The Square Codex team is easy to work with and very communicative. We found a particularly excellent QA Engineer through them who worked on several of our client projects – they were thorough and wrote solid documentation to accompany their QA.

We have used Square Codex for over 2 years and found them to be very helpful in the candidate search process and the staff augmentation services after engagement.

Square Codex fosters transparency, proactivity and open communication. They had a can-do and collaborative attitude. Their high-quality developers are very well-adjusted to our timeline, development cycle, and requirements.
