—they combined deep technical expertise with proactive communication, swiftly adapted to changing priorities, and maintained a genuine commitment to our business goals, resulting in a collaborative, transparent process where we always knew the project status and felt confident that any issue, big or small, would be handled promptly and effectively.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Techsevin structured the engagement around an Agile framework, breaking the work into two-week sprints with clearly defined sprint goals and deliverables. At the start of each sprint, they facilitated a planning session where we reviewed the backlog, prioritized features, and agreed on acceptance criteria. Throughout the sprint, they held twice-weekly stand-ups to update us on progress and surface any blockers. This cadence ensured that each module—whether a new front-end component, back-end API, or integration connector—had a committed delivery date. In practice, over 90% of those sprint commitments were completed on or before the planned demo date, with only minor slip in one sprint tied to a sudden third-party API change (which they immediately flagged and mitigated by reallocating resources).
Whenever we submitted change requests—whether for a last-minute UI tweak, an updated payment-gateway requirement, or an urgent bug fix—Techsevin responded within 24 hours. They maintained a shared Clickup board where tickets were triaged daily; high-priority items were reassigned to their “fast-track” swim lane so that critical issues never languished. If a requested feature risked impacting the current sprint goal, they would promptly schedule a short scoping call (often the same day) to discuss trade-offs, adjust timelines, and reset expectations. In all cases, they communicated clearly: if a request could be accommodated in the current sprint without jeopardizing other deliverables, they’d confirm that during the next stand-up; if it required shifting scope, they’d propose a revised delivery date before moving forward.
Their responsiveness extended beyond just reactive fixes. Every two weeks, in addition to the sprint review, they held retrospective sessions in which they solicited our feedback on communication, quality, and prioritization. When we noted we wanted more detailed release notes, they incorporated a standardized “changelog” document into each sprint’s artifacts. When our marketing team flagged a need for extra QA around peak-traffic simulation, Techsevin scheduled two dedicated performance-testing passes—and provided a mid-sprint report on load tests—without delaying core feature rollouts.
In summary, Techsevin consistently delivered committed user stories on time, rapidly addressed emergent requirements or blockers, and adapted their process whenever we raised new needs. Their combination of rigid sprint cadences for planned work and a flexible, well-structured triage process for unplanned needs ensured that we always knew where the project stood and that our priorities were reflected immediately in their backlog. , and when unexpected issues—like a third-party API change—arose, they immediately flagged them, reallocated resources, and communicated revised timelines so that any delay was minimal; additionally, their 24-hour response to urgent change requests and daily ticket triage ensured that critical fixes never stalled progress, demonstrating reliably prompt delivery throughout the project.
What was your primary form of communication with Techsevin Solution LLP?
- Virtual Meeting
- Email or Messaging App
What did you find most impressive or unique about this company?
What stood out most was Techsevin’s rare combination of deep technical expertise and genuine client partnership. From day one, they not only understood our e-commerce domain but also proactively suggested optimizations we hadn’t considered—whether that meant refactoring a complex checkout module to improve performance or proposing a smarter caching strategy to reduce server load. Their willingness to own both the big-picture architecture and the smallest bug fixes felt unique; instead of passing issues between front-end, back-end, or DevOps teams, they treated every part of the system as “our” responsibility.
Equally impressive was their communication style. They ran tightly organized two-week sprints but never hid behind rigid sprint boundaries. If an urgent marketing push required a last-minute UI tweak, we’d get a prototype the same day, complete with performance metrics and QA results. That blend of agility and accountability is hard to find—most providers are either fast but sloppy or meticulous but slow. Techsevin managed to be both fast and faultless.
Finally, their culture of continuous improvement felt genuine. In retrospectives, they solicited feedback not just on deliverables but on how they partnered with us—then immediately adjusted things like release-note formatting, reporting cadence, and even their sprint demo style. That level of self-awareness, combined with a willingness to iterate their own process, made them feel less like an outsourced vendor and more like an embedded member of our team. Techsevin delivered a robust, scalable e-commerce solution at a competitive rate—achieving a 30% reduction in monthly operational costs and recouping the entire development investment within nine months—while their proactive optimizations (like automating order processes and improving performance) translated into clear savings; in comparison to other vendors who quoted similar features at higher rates or with lower guarantees of ROI,
Are there any areas for improvement or something Techsevin Solution LLP could have done differently?
While our experience with Techsevin was overwhelmingly positive, there were a few areas where they could have refined their approach:
More Proactive Risk Assessment Upfront
During the early planning phase, Techsevin delivered a solid technical design, but we later encountered unanticipated third-party API changes that briefly delayed one sprint. A more thorough risk assessment—especially around external integrations—could have identified those potential points of failure earlier. For example, building a small “sandbox” test harness for each payment or shipping provider before committing to the production integration might have highlighted version-mismatch issues sooner.
Deeper Early Documentation of Business Rules
As we evolved our promotional logic (tiered discounts and BOGO offers), some of the edge cases in our business rules weren’t captured in the initial requirements document. That meant mid‐project clarifications were needed whenever we ran a complex sale scenario. Techsevin was excellent at responding, but spending a bit more time on domain discovery—documenting all coupon combinatorics, customer-group pricing exceptions, and “what-if” scenarios—would have reduced back-and-forth later on.
Slightly Faster Knowledge Transfer to Internal Teams
We appreciated the training sessions Techsevin provided for our operations and marketing teams, but some of the deeper “how it works under the hood” sessions came toward the end of the engagement. Having key administrators shadow Techsevin engineers earlier—especially when the admin panel and ETL scripts were being built—would have accelerated our in-house onboarding. This would also have minimized the learning curve once Techsevin transitioned into maintenance mode.
More Granular Roadmap of Post-Launch Enhancements
After go-live, Techsevin delivered on bug fixes and queued up minor enhancements promptly, but a more detailed 3- to 6-month roadmap outlining planned feature rollouts (e.g., loyalty module, multi-warehouse support, A/B testing infrastructure) would have helped us align marketing campaigns and staffing decisions more proactively. In some cases, we weren’t sure if a feature was slated for next quarter or further out, and that occasionally led to parallel work by our internal team.
Early Performance & Load Testing in a Production-Like Environment
While the final performance results were excellent, we only ran full load tests after most of the core features were built. If we had scheduled an earlier “peak-load simulation”—perhaps as soon as the checkout flow was feature-complete—we might have discovered certain caching or database-index tweaks sooner. This might have reduced the number of small, last-minute optimizations needed just before launch.
Summary:
Overall, these are relatively minor points in what was an otherwise smooth, highly collaborative engagement. Addressing them would further reduce friction around scope changes, speed up internal knowledge transfer, and mitigate any last-minute surprises—making a great partnership even stronger, as they consistently delivered high-quality, on-time work, offered exceptional value through cost savings and rapid ROI, and maintained clear, proactive communication that made collaboration smooth and effective.

We evaluated multiple partners using different metrics and criteria. Then we eventually narrowed the list down to Techsevin Solution LLP. After completing a small project, we knew they had potential.
What is the status of this engagement?
We started working with them around January 2016, and our partnership is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Our company has seen a 100% year-over-year growth in sales — this wouldn’t have been possible without Techsevin Solution LLP. For four years, their team has successfully delivered our technological vision and mission. Working on a time-and-materials basis, we’ve tracked the number of project deliveries, timeliness, and overall scalability.
How did Techsevin Solution LLP perform from a project management standpoint?
Project management is great overall, but there are areas where they could become more solution-driven. However, this depends on the workload or situation and doesn’t happen all the time. The noteworthy characteristic of their team is that they stick to commitments.
What did you find most impressive about them?
Their work ethic is outstanding. Given the way we run business, from handling changes to financials, their attitude toward working as a team is great. They have some improvements to make but overall, they follow through on every commitment. This is why we’ve continued working with them for so long. We haven’t thought about shifting to any other vendor.
Are there any areas they could improve?
They could improve on delivery processes, in terms of following strict subversioning, planned deliveries, and sprint processes. Right now, it’s not always done properly, and these are the areas where I have to keep control and be on top of the job.
Do you have any advice for future clients of theirs?
I advise future clients to be on top of the process to ensure things turn out correctly.
