/05CASE STUDIES

Not “what we built”
but “what we solved”

Problems UNISYS has actually solved in client and production environments. Industry, problem, solution, and result captured in a single card.

W-01 · 2025Cloud · DevOps

Cloud Deployment Automation

ProblemECR, EC2, and Docker deployments were manual and scattered, driving up operating costs and outage risk.
SolutionUnified deployment and monitoring through a single desktop console and an automation pipeline.
ResultDeployment time cut 78%, and overnight incident response time more than halved.

W-02 · 2025SaaS · Email

B2B Email SaaS

ProblemB2B clients with multiple domains couldn't manage sending, receiving, and analytics from a single screen.
SolutionBuilt a SaaS with a multi-tenant data model, a send queue, and per-domain policies.
ResultAverage 1.4 fewer operations staff per client and automated domain reputation measurement.

W-03 · 2024Event · Ticketing

Seat Data Platform

ProblemVenue seating was managed only in spreadsheets and floor plans, disconnected from sales and operations systems.
SolutionTurned seating into data and connected it to sales and ticketing systems via a standard interface.
ResultSeat-layout setup for a new event dropped from 12 hours to under 30 minutes.

W-04 · 2025Media · Streaming

Live Streaming Platform

ProblemHeavy reliance on external OTT/streaming solutions left operators with little direct control.
SolutionBuilt RTMP ingest, broadcasting, and a monitoring console directly on our own infrastructure.
ResultMonthly broadcasting costs cut 60%, and adding a channel down to under 5 minutes.

/07PROCESS

From Discovery
to Operate

It doesn't end at launch. We work as one team that owns the product all the way through operations.

01

Discovery

We organize requirements, business goals, and technical risks, and set priorities.

02

Design

We design information architecture, screens, data models, and architecture together.

03

Build

We build frontend, backend, and infrastructure in parallel and validate as we go.

04

Launch

We own deployment, domains, monitoring, and operational environment setup directly.

05

Operate

We operate alongside you on incident response, performance, and feature expansion.

/08OPERATING PRINCIPLES

How we work,
in six principles

A small team never means less operational responsibility. Every decision is made on top of these six principles.

01PRINCIPLE

Small Team, High Ownership

A small team that works by owning everything from design to operation.

02PRINCIPLE

Built to Operate

We design for operability after launch from the very start.

03PRINCIPLE

Cloud Native

We design systems with cloud, containers, and automation as the baseline.

04PRINCIPLE

Product First

We favor sustainable product architecture over one-off development.

05PRINCIPLE

Security by Design

We build auth, permissions, logging, and data protection into the initial design.

06PRINCIPLE

Global Ready

We keep service design principles that account for Korean, Japanese, and English.
