AI-era engineering
AI can write code. Engineering makes it reliable
AI tools are useful, but complex products still need architecture, risk control, integrations, performance, and someone who understands what happens under the hood.
Ideas become real when they are tested
SOLE TARGET LTD
Software R&D for ideas, prototypes, and complex systems made clear, buildable, and usable
We help founders and companies turn difficult technical ideas into working software: prototypes, proof-of-concept systems, backend platforms, APIs, automation tools, device-connected systems, and video/data processing solutions.
We help founders and companies turn difficult technical ideas into working software: prototypes, PoCs, backend platforms, APIs, automation, device-connected systems, and video/data processing.
When the task is unclear, risky, or technically unusual, we help define the right path before development becomes expensive.

What we do
We turn technical uncertainty into a buildable plan
SOLE TARGET helps you clarify the problem, choose the right technical direction, test the riskiest assumptions, and build software that is practical to use and maintain.
- Clarify the real technical problem before full investment
- Build prototypes that answer concrete feasibility questions
- Design architecture that can grow without becoming fragile
- Turn complex logic into simple user-facing workflows
Prototype first
Ideas worth testing deserve working prototypes
Innovation does not have to start with a large team or a long development cycle. A clear prototype can answer the most important questions early: what is possible, what is risky, what users actually need, and what should be built next.
From Vietnam, SOLE TARGET works with founders and companies who want to test new digital products, improve business processes, connect systems, automate work, or explore technically unusual ideas.
Start with a prototypeExpertise areas
Practical engineering for systems with real constraints
We focus on the core technical layers that determine whether a product can scale from idea to reliable use.
R&D
R&D, prototypes, and proof of concept
We validate technical ideas before full investment and turn uncertainty into a practical build path.
Architecture
Architecture and backend platforms
We design durable software cores, service boundaries, data flows, and backend platforms for complex products.
APIs
API design and system integration
We connect products, devices, tools, and third-party services through clear, maintainable API layers.
Automation
Automation and internal tools
We simplify operational workflows with reliable software that reduces manual work and repeatable errors.
Devices
Device-connected systems
We build interfaces and backend logic for software that works with sensors, hardware, and edge environments.
Vision
Video and data processing
We create pipelines for capture, processing, analysis, storage, and controlled access to data-heavy workflows.
Where we are strongest
Best fit for problems that need engineering judgment
The idea is promising, but the technical path is unclear
We help define what should be tested first and what can wait.
You need to validate a complex idea before scaling it
We build proof-of-concept systems that test feasibility, constraints, and risks.
Multiple systems, APIs, devices, or data flows must work together
We design the architecture and integration logic so the system behaves predictably.
An existing product became too complex or fragile
We help stabilize, simplify, or rebuild the parts that limit future growth.
How we work
A direct path from uncertainty to buildable software
We start with the smallest useful step that reduces uncertainty.

Example systems
Examples of systems we can help with
These are public, non-confidential directions based on our engineering experience.
Booking and operational platforms
Custom workflows for availability, scheduling, payments, internal roles, and service delivery logic.
API-first business systems
Backend platforms with clear service contracts, integrations, access rules, and maintainable data models.
Automation and control dashboards
Focused tools for teams that need visibility, repeatable actions, and fewer manual operational steps.
Device and sensor interfaces
Software layers that collect, normalize, monitor, and expose data from device-connected environments.
Video processing pipelines
Capture, transform, review, and delivery workflows for systems where video is part of the product core.
Prototype-to-production systems
A practical path from technical discovery through prototype validation and production-grade development.
Distributed monitoring systems
Systems that collect signals across devices, services, or locations and make problems easier to see.
Scientific, industrial, and data-heavy tools
Focused software for workflows where data, constraints, and reliability matter more than generic features.
Also relevant: distributed monitoring systems, scientific and industrial software, and data-heavy engineering tools.
Confidentiality and IP
Client work stays confidential
We respect NDAs, internal product information, and intellectual property.
For private projects, we do not publish screenshots, client names, or sensitive technical details.
We can demonstrate expertise through a technical conversation, architecture examples, selected non-confidential materials, or a focused discovery session.
