Chapter 01 / What We Build
Three core services, one standard: clean, fast, and built to be used. Pick what fits your business best.
Present & credible
Company profiles, landing pages, up to online stores. Fast, responsive, and ready to become your business's credibility engine.
Systems that fit your workflow
Dashboards, internal systems, or e-commerce platforms built around your business process — not the other way around.
In your customers' hands
Cross-platform Android & iOS apps — from design and development all the way to publishing on the Play Store and App Store.
Chapter 02 / Selected Work
Every project starts with a real problem. Our job is to translate it into interfaces, code, and systems people can use every day.
An ERP system for KJ Homedecor's premium curtain business — product catalog, installation portfolio, consultation booking, and marketplace integration on one platform.
Custom curtain operations were split across channels: catalogs lived on marketplaces, orders arrived via WhatsApp chats, and portfolios were scattered with no central source of data.

A travel company profile featuring domestic & international tour packages, favorite destinations, traveler testimonials, and a blog — everything leads to WhatsApp.
Package details and trust signals only moved from chat to chat; prospective travelers had no tidy way to browse the catalog or check the track record.

The official portal of the SF Winner sports club — branch profiles, online registration, fixtures & results, galleries, and coverage of AAFI leagues from U-6 to U-16.
Fixtures, league results, and futsal & swimming registration info were scattered across group chats and posters that quickly got buried.

Chapter 03 / The Journey
Founded by Okky Hidayana., Calysta Tech grew from curiosity into a studio that helps businesses show up digitally — complete, clean, and ready to use.
It started with curiosity about the web. From HTML and CSS, we built a first website just for the sake of learning.
Diving into SEO and digital marketing. Here we learned one thing: a good website also has to sell.
Expanding into React, Node.js, and Flutter. Real client projects started coming in — from web apps to mobile apps.
A studio focused on building end-to-end digital products: websites, web apps, and mobile apps that are clean and ready to use.
Chapter 04 / The System
Our capabilities are grouped by their role in the process — designing, building, then shipping products into users' hands.
