OPPORTUNITY / CHALLENGE

What specific goals or objectives did you hire ZirconTech to accomplish?

• We hired ZirconTech to deliver backend/API development in Java, with the goal of producing maintainable, well-structured, and professionally tested code that could be integrated into a client project without causing rework

SOLUTION

• Online Search
• Clutch Site

Why did you select ZirconTech over others?

• High ratings
• Close to my geographic location

How many teammates from ZirconTech were assigned to this project?

2-5 Employees

Describe the scope of work in detail. Please include a summary of key deliverables.

The scope of work included backend/API development in Java and DevOps support on Google Cloud Platform. ZirconTech was responsible for designing and implementing API endpoints, following proper code conventions, adding unit tests, logging, and error handling, and ensuring the codebase was production-ready. In addition, we contracted a GCP DevOps engineer from their team to handle infrastructure setup, deployment pipelines, and cloud resource configuration. Key deliverables were: (1) properly structured and documented API endpoints aligned with specifications, (2) tested and maintainable backend modules, (3) DevOps support for CI/CD and cloud infrastructure, and (4) documentation for both code and deployment processes.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

The only partial success in this engagement was the GCP DevOps engineer, who supported our cloud infrastructure and CI/CD needs appropriately. However, the backend/API development was not successful: the endpoints delivered were incomplete, lacked proper testing, logging, and error handling, and required us to redo significant portions of the work. As a result, while we saw some progress on the DevOps side, the project overall produced no measurable positive outcomes and created additional cost and reputational risk with our client.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Project management was poor. Items were not delivered on time, and when issues were raised, ZirconTech responded with superficial artifacts (such as Postman screenshots of 200 responses) instead of addressing the underlying quality concerns. They did not demonstrate accountability or a structured approach to delivery, and communication often deflected rather than resolved problems. When we escalated concerns about a developer’s behavior, they failed to handle the matter internally, leaving us to deal with the fallout directly. This lack of governance compounded delays, rework, and additional cost. The only exception was the GCP DevOps engineer, who was responsive and reliable within his scope.

What was your primary form of communication with ZirconTech?

• Virtual Meeting
• Email or Messaging App

What did you find most impressive or unique about this company?

The only positive aspect was the responsiveness of the individual GCP DevOps engineer we engaged, who worked reliably within his scope. Beyond that, we did not find anything impressive or unique about the company.

Are there any areas for improvement or something ZirconTech could have done differently?

There are several areas for improvement. First, ZirconTech needs to deliver work that meets professional software development standards: proper code conventions, testing, logging, and error handling should be mandatory. Second, they must implement real project management practices, with accountability for timelines and deliverables, instead of deflecting with superficial artifacts. Third, they need to address personnel issues internally — when we raised concerns about a developer’s behavior, nothing was done. Finally, they must respect contractual boundaries; contacting our clients directly was a breach of trust and of our master agreement. Had these areas been handled correctly, the project outcome could have been very different.

Company Responses

The service provider responded on August 14, 2026.

Thank you for the feedback. We see this engagement differently, and we think readers deserve the context.
This was a time and materials staffing engagement rather than a fixed scope delivery project. Between June and September 2025 we placed two engineers, a GCP DevOps engineer and a Java Tech Lead, into our client's end client team, working under that team's technical direction and billed hourly against signed SOWs. There was no fixed deliverables list and no fixed price.
There is context the review leaves out. An invoice from this engagement remains unpaid, and the quality concerns described here were raised for the first time when that invoice came due. July and August hours for both engineers were approved and paid without objection, and the Java engineer's assignment was extended by signed addendum on 28 August through the end of October. We asked for documentation of the technical deficiencies described here and never received any.
On one point we want to be direct. We did contact the end client once, in October, after we were told our invoice would not be paid because the end client had refused to pay it. We had already spent more than a week trying to resolve this with our client directly, by message and by phone, and those attempts went nowhere. We asked the end client a single question, which was whether the statement made to us was accurate. We solicited no business and shared no confidential information. Our agreement contains non solicitation and confidentiality clauses, and neither one covers that question.
We remain willing to resolve the commercial matter directly.

BACKGROUND

Please describe your company and your position there.

Partner and company representative in Latam for consulting company based in Austin Texas.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire ZirconTech, and what were your goals?

A network like that of Ethereum is not suitable for handling large volumes of data or storing files, therefore a feasible solution is to calculate a hash that represents this file in a plain text format that can be stored as part of a block. It is then the job of a centralized system to ensure that this hash stored on the blockchain is kept consistent with its original file. That said, we needed to implement a software product that provides the necessary functionality to solve this problem, as well as additional functionality, in such a way that it could be adaptable to multiple use cases. In addition, this project also sought to promote interest, knowledge, and practical exercise in the Blockchain world.

SOLUTION

How did you select this vendor and what were the deciding factors?

ZirconTech has been developing projects on the Blockchain for several years and enjoys good references. They were recommended to us through mutual contacts.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

Smart Contracts were designed to support the fundamental requirements of the system. The following was determined: What was the best way to model and represent the data? What features should they have? What parameters should they receive? validations modifiers Execute permissions using auxiliary contracts (eg onlyOwner) In addition, the contracts had to support data mapping for each user account as well as different levels of access to functions. So it was important to evaluate whether to keep a simple structure in a centralized contract or dynamically instantiate contracts.

The system had the following components and stack:

• REST API in NodeJS
• Typescript
• NestJS
• Web3
• Jest
•  Swagger Smart Contracts on Ethereum
• Solidity Web Application in React JS
• Redux
• Axios
• VueJS
• Infrastructure with Github Actions
• AWS EB
• Serverless MongoDB

How many people from the vendor's team worked with you, and what were their positions?

A frontend developer for the interface A backend developer for services, database, file upload, etc. A blockchain developer for the elaboration of the smart contract and the integration with several blockchains (ethereum, polygon, tezos, etc)
