      eCommerce Development Review from Sarika Dhami

      I started Lunera selling handmade candles and soaps through TikTok and WhatsApp. It was working, but I knew we needed a real home on the internet. Something that felt like the brand, had an actual store, and something I could manage without calling a developer every time I wanted to change a product photo or update a banner. I found AlpineRoot Technologies Pvt. Ltd. through a referral and they took on the whole thing. Design, development, ecommerce, and SEO as one project. The design was what I was most uncertain about going in. Our products are handmade and the brand has a particular feel to it, warm and earthy, soft creams and deep browns. What came back matched that completely. The product cards show each candle or soap on its own textured stage in those same tones, and those cards are the detail customers mention when they visit the site. The Fraunces serif for headings gives it a quiet editorial feel which was exactly what I had described wanting. The admin panel is what I use every single day now. Adding products, uploading photos, managing orders and coupons, writing blog posts, editing the homepage and navigation, all without needing anyone else. The dashboard shows revenue, profit and margin, and pulls in WhatsApp sales too so I can see everything in one place. I did not expect that level of control from day one. Before launch, the team caught a bug where two customers placing orders at the same time could have bought the same product. They fixed it without being asked. I only found out when reading through the documentation they had written. They also removed placeholder testimonials from the design rather than leave fake ones in. Both things I noticed after the fact. Google Search Console was already showing impressions and clicks within the first month. Communication throughout was clear. Revisions were handled without fuss and the team did not move forward on anything until I had confirmed I was happy with the direction.

      Web Design Review from Neerajan Panta

      Six months ago, our website brought in about 2 enquiries a week. Today we average around 5 enquiries a day. The change came from the new website AlpineRoot Technologies built for us. They designed the site from scratch around how people actually look for a moving company, instead of fitting us into a template. Pages load quickly, work well on a phone, and make it easy for a visitor to ask for a quote. That last part matters most for us, because most of our customers find us and decide on their phone. The custom CMS has also made life easier for our team. We can update services, publish blog posts, and change page content ourselves without waiting on a developer. The site stays current because editing it is simple. AlpineRoot was clear about scope and timelines, communicated directly, and kept supporting us after launch. We would recommend them to any business in Nepal that wants a website that brings in real customers, not just one that looks good.

      Web Design Review from Sandesh Panta

      As an EV scooter dealership entering a market that is still fairly new in Nepal, we needed a brand identity and website that felt credible, modern, and trustworthy right from the start. AlpineRoot Technologies delivered exactly that, and they did it in under three months. They treated our custom website, logo design, and overall branding as one connected package instead of handling each piece in isolation, and it shows. The logo captures the energy and modern feel we wanted for an EV brand without coming across as generic or overworked, and that same visual language runs consistently through the website and the rest of our brand identity. Nothing feels disjointed or like it was pieced together from different templates. The website itself was built entirely around how our business actually operates, not adapted from some generic dealership template. It looks clean, professional, and distinctly ours, which matters a great deal in a category where customers are still building trust in EVs as a whole, let alone in a specific brand. What stood out just as much as the final product was the process behind it. AlpineRoot took the time to genuinely understand our positioning as an EV brand before starting any design work, and that groundwork showed in the result. They stayed responsive throughout, welcomed revisions, and never cut corners on the branding just to hit a deadline, even with a fast overall timeline. We also got quotes from a few other agencies before choosing AlpineRoot, and they turned out to be the most affordable option while still offering the strongest value overall. For a Nepal based company, the level of design thinking and execution they brought to our brand identity was genuinely impressive. For any business looking for a design and development partner capable of building a cohesive brand from the ground up, not just a website, AlpineRoot Technologies is worth talking to.

      Software Development Review from Grzegorz Grabczak

      We worked with Zealous System on an AI-powered fraud triage solution for one of our clients in the Europe financial services sector. The project involved a complex fraud investigation workflow where analysts were handling a large number of alerts and gathering information from multiple systems. Zealous System worked closely with us to understand the requirements, existing processes and expectations of the end client before moving into development. The team developed an AI-powered fraud triage agent that brings relevant information together, helps prioritise alerts and provides explainable recommendations while keeping human analysts involved in important decisions. What I appreciated was the team's ability to understand both the business and technical sides of the project. Communication was consistent, and they were responsive when requirements evolved during development and testing. The solution helped streamline the investigation process and reduce the amount of repetitive manual work involved in reviewing fraud alerts. Overall, we had a positive experience working with Zealous System. They were a reliable technology partner for us on this project, particularly given the complexity of introducing AI into a financial services environment.

      DIPAK VAIDH's Review Sourced from Google

      I visited Zealous System on 16th June 2025 for the walk-in interview announced on LinkedIn for interns/freshers in Python, PHP, WordPress, .Net, and QA roles. Despite clearly stating it was open for freshers, upon arrival, all Python candidates, including myself and my sister, were told they only accept those with prior experience, as interns are directly placed on live projects. This information was never mentioned in the post. The company blamed the marketing team for the misleading post. This experience wasted our valuable time, energy, and travel expenses. I urge the company to coordinate better internally and post accurate job/internship information to avoid misguiding freshers who genuinely seek opportunities.
