WHY QUALITY MATTERS

InvestinQuality.AvoidBrokenSystems.

Many software projects fail not because of technology, but because they are built with rushed architecture, short-term thinking, and code that cannot evolve. Cheap software often becomes the most expensive business decision. At ZELLIO, we engineer software that remains maintainable, scalable, secure, and reliable for years.

01

Dedicated Engineers

Our team consists of full-stack developers, UI/UX designers, and technical specialists working dedicatedly on each project.

02

Modern Technology Stack

We leverage cutting-edge tech stacks (React, Next.js, Node, TypeScript) for maximum performance, security, and scalability.

03

Security Review

Security is integrated into every layer from day one, following industry best practices and protecting your digital infrastructure.

04

Reliable Delivery

We combine dedicated engineering with an agile, transparent development process to ensure reliable delivery on time.

TESTIMONIAL

What They Say

Before, during peak seasons like Eid and TAB, our warehouse team struggled with manual courier routing. With Zellio's tracking system, driver routes are clustered automatically. It really cut down our sorting time.

MK

Muhammad Kamalluki

RACE Raja Cepat

We expected integrating this dashboard with our legacy Odoo core to be buggy and complex. But the Zellio team handled the middleware flawlessly. Vendor PO invoicing, which used to be a manual mess, now syncs automatically with zero errors.

AH

Ahmad Husaini

Eureka Group

Speed is everything in online travel booking. Our old site lagged when fetching airline API data. After Zellio rebuilt it with Redis caching, ticket searches became extremely fast. Users no longer drop off due to slow loading.

AD

Alan Dandi Siregar

MasterDiskon

We needed a lightweight educational landing page that still looks clean and professional. The water intake calculator has been a huge hit with our users. The team was highly responsive with content updates.

AN

Astri Novianti

Batugin

Our biggest challenge was driver battery drain from background GPS tracking. Zellio's React Native optimization fixed this, keeping battery usage low and geofencing order dispatch highly accurate.

AD

Aji Darusdi Pramana

Beego SuperApp

I was hesitant to build a custom e-menu fearing it wouldn't sync with our kitchen printers. Zellio built a seamless WebSocket bridge. Now, web orders instantly trigger the kitchen printer.

ED

Ester Damayanti

Warung BungaPagi

During major sales, our server often crashed at checkout due to inventory race conditions. Zellio helped us refactor our database architecture using MongoDB transactions. Now, mass checkouts go smoothly with zero inventory errors.

RP

Reza Pahlevi

Jaja ID

The biggest pain on our old site was displaying side-by-side car spec comparisons. The layout frequently broke on mobile. Zellio's dashboard and catalog design are extremely neat, and the credit simulator is simple for buyers to use.

HT

Hendry Tan

Jaja Auto

A law firm website must project high authority and professionalism. Zellio captured this perfectly with a clean, modern-minimalist design. The consultation calendar integrated with our Google Calendar has cut scheduling conflicts.

MC

Marcus Campos, S.H., LL.M.

Campos Law Firm

Our B2B clients are thrilled they no longer need to email back and forth for invoices or container status updates. They can download shipment data directly through this portal. It has greatly relieved our customer service team.

BS

Bambang Sugiharto

Eureka Logistics Portal

Calculating PPh 21 and BPJS taxes for thousands of employees at the end of the month was a HR nightmare. Zellio's HR dashboard automates payroll calculations instantly. Plus, salary data encryption gives us peace of mind regarding employee privacy.

NA

Niken Ayu Lestari

HR Management CMS

Tutor video calls used to disconnect when a student's internet slowed down in remote areas. Zellio's WebRTC classroom module is highly adaptive, automatically lowering video resolution while keeping audio clear. The payment escrow system is also secure for mentors.

AR

Arief Rahman

Guruino

Watching together is no fun if the video is out of sync. The WebSockets built by Zellio sync down to the video frame, so everyone in the room watches the same scene in real-time. The live chat doesn't lag even under heavy load.
