SOC2 Technical Readiness and Evidence Environment Implementation : Milestone 1
I had an excellent experience working with Himanshu on a large and technically demanding Azure infrastructure, cloud security, and SOC 2 readiness project for our production software platform.
This was not a simple development assignment. The engagement involved reviewing an existing production Azure environment, identifying and correcting security and configuration issues, designing and implementing a dedicated SOC 2 evidence environment, configuring logging and monitoring across multiple Azure services, implementing long-term evidence retention and immutable storage, configuring access controls and privileged access management, building alerting and evidence-collection mechanisms, integrating GitHub security and deployment evidence, developing KQL queries, and performing extensive end-to-end validation and remediation.
Himanshu worked through a number of complex issues that only became apparent during actual implementation and testing. Importantly, he did not simply configure controls and assume they worked. The environment was repeatedly tested, defects were identified, corrected, retested, and documented. This included troubleshooting Azure diagnostic and evidence-export behavior, retention and archive configuration, alerting, deployment-related configuration changes, access controls, and other issues that required careful investigation rather than superficial fixes.
He also produced a very substantial final documentation and handover package, including architecture and data-flow documentation, resource and evidence inventories, access-control documentation, testing and validation records, operational runbooks, query libraries, change documentation, and a final SOC 2 evidence crosswalk intended for review by external SOC 2 readiness and audit professionals.
One thing I particularly appreciated was his willingness to continue working through problems when unexpected issues arose. Several times during the project, testing uncovered behavior that was different from what the Azure configuration initially appeared to indicate. Himanshu investigated the underlying cause, corrected it, retested the environment, and helped establish a much stronger final configuration rather than simply documenting the original state as acceptable.
The project involved an active production system, so changes had to be made carefully without disrupting users or normal operations. Throughout the engagement, the production platform remained operational while substantial infrastructure, security, monitoring, and evidence work was performed around it.
This was a significant engagement involving many hours of engineering, validation, troubleshooting, remediation, and documentation. Himanshu demonstrated strong knowledge of Azure, infrastructure-as-code, GitHub, identity and access management, logging and monitoring, security controls, DevOps, and SOC 2 technical readiness.
I appreciate the amount of effort he put into the project and his persistence in getting the work into a final state suitable for external review. I would be very comfortable working with Himanshu again on Azure infrastructure, cloud security, DevOps, compliance readiness, or other technically complex projects.
Highly recommended.

GitHub migration from personal to Enterprise
Himanshu did an excellent job migrating my private repositories from my personal GitHub account into a new GitHub organization. This was a live production application, so avoiding downtime and making sure the deployment process continued to work correctly were extremely important.
He carefully reviewed the repositories, GitHub Actions, permissions, secrets, Azure OIDC configuration, and CI/CD workflows before making changes. He created a full backup, prepared the migration properly, completed the repository transfer, updated the required Azure and GitHub settings, and verified that both authentication and the live application continued working afterward.
He was thorough, careful, responsive, and clearly understood the risks involved with making changes to a production SaaS platform. He also documented the work and flagged a separate infrastructure-code issue that could have caused problems during a future redeployment.
The migration was completed successfully without disrupting the live website. I would definitely hire Himanshu again for GitHub, Azure, CI/CD, or SaaS infrastructure work.

Quran Web App Development
Here is a stronger, cleaner version you can send to Upwork:
I hired this freelancer to improve my existing Qur’an learning app in terms of design, functionality, user experience, and overall quality. I provided him with my original working code and asked him to review it and confirm whether he could improve it.
Unfortunately, every version he delivered was lower quality than my original work. The delivered app did not improve the design, functionality, or learning experience. Instead, it removed or weakened my original branding, used a generic dashboard layout, duplicated navigation, wasted screen space, and failed to provide a better educational experience than the original app I had already built.
The project is now almost a month past the agreed deadline which was April 14, 2026. I also gave the freelancer multiple opportunities to correct the work and provide something better than my original app. However, each time, he submitted incomplete or low-quality work and asked me to review it and provide more feedback, instead of delivering a complete and improved product.
The purpose of the contract was not simply to build something different or to start something from the start. The purpose was to improve my existing app. Since the delivered work is late, incomplete, and lower quality than what I originally provided, it does not meet the agreed purpose of the contract.
For these reasons, I am requesting a full refund of the escrow funds.
