Software & integration
Custom applications, backend platforms, and system integration built around real operational needs.
Callysta Engineering · Bandung, Indonesia
Software. Electronics. Connected products. We bring decades of hands-on engineering to an AI-powered way of designing, building, and validating technology.
01 / Our story
Callysta’s engineering story began in 2000—ten years before the company was formally incorporated.
Our projects span custom software, embedded hardware, CallystaDNA appliances, EduLabs learning technology, identity systems, IoT, and smart metering—including PLN’s STS prepaid vending server. Across these disciplines, the purpose has stayed the same: make complex technology useful in the real world.
In 2026, we are bringing AI into that accumulated experience—from software and firmware to schematic capture, PCB layout, and industrial design, with a growing role in validation, pilot builds, and manufacturing preparation.
New tools. The same engineering discipline.
02 / What we engineer
Our strength is not a single technology. It is the ability to connect software, electronics, industrial design, and operations into one dependable solution.
Custom applications, backend platforms, and system integration built around real operational needs.
Custom electronics, firmware, connected devices, and telemetry—from the circuit board to the management platform.
Computing, networking, and storage in purpose-built hardware, continuing the multidisciplinary approach behind CallystaDNA.
Metering systems and STS prepaid-meter token generation, drawing on our experience with PLN’s prepaid vending server.
Biometrics, public-key infrastructure, smart cards, and access control—connecting trusted identity with everyday operations.
Interactive media, simulation, and virtual laboratories, building on Callysta EduLabs’ work in science and mathematics.
Proven in critical infrastructure
Our experience includes PLN’s prepaid vending server: a system that generates tokens for STS prepaid electricity meters. It brings together the software, services, and operational integration behind prepaid metering.
That experience also extends to industrial and military solutions, where software, hardware, and system integration must work together around demanding operational requirements.
Engineering facilities
Our engineering facilities and specialized equipment support the hands-on work behind a dependable product: prototyping, measurement, debugging, and physical validation.
Schematic capture, PCB development, firmware bring-up, measurement, and technical diagnosis.
Iterative product, enclosure, and test-article development for earlier physical feedback.
Real-device commissioning and cross-layer verification from software command to physical response.
Controlled pilot builds, repeatable procedures, and preparation for reliable manufacturing.
03 / The next chapter
AI is becoming part of how we engineer—not just how we generate ideas. Our human-directed workflow connects tools, specialist agents, and real-world validation.
Engineering tools, infrastructure, and knowledge tuned around how Callysta works.
Decisions, artifacts, and lessons remain available throughout long-running programs.
Models and tools are selected to suit the discipline, task, and validation needs.
Human-directed specialist agents collaborate through controlled, traceable handoffs.
Hardware-in-the-loop workflows connect software actions with real devices and measured responses.
Versioned code, build artifacts, validation evidence, and deployment records make work reviewable and repeatable.
Human-directed. Evidence-driven.
Engineering judgment sets the direction. AI helps teams explore, execute, and verify—with people accountable for the outcome.
04 / What comes next
Bring us the challenge that needs more than an off-the-shelf answer. We’ll bring the disciplines, experience, and intelligence to move it forward.
