Software Engineering Consultancy
Engineering that moves your business forward
We partner with organizations to build, modernize, and maintain software systems. Deep technical expertise, clear methods, lasting results.
Technical Competencies
What we spend our time on
We are not generalists. Our practice covers a defined set of technical disciplines where we have deep, tested experience. Each area has senior people, established methods, and a clear point of view.
Software product engineering
Systems designed around the business domain, not the framework of the month. We model the problem carefully, build incrementally, and write code intended to last.
Human-computer interaction and design
Interfaces shaped by research, not guesswork. We study how people actually work and build tools that fit into those patterns instead of interrupting them.
Cloud architecture and reliability
Infrastructure that does what you expect. We size things correctly, automate what matters, and design for the kind of failures that actually happen.
Data engineering and intelligence
Data pipelines you can trust and audit. We build systems where the numbers are right, the lineage is clear, and analysts can do their work without calling engineering.
Legacy modernization
Careful, incremental work on the systems your organization depends on. No big-bang rewrites. Each step delivers something and reduces risk.
Quality and testing
Testing built into the process, not bolted on at the end. We design strategies that catch real problems early and give teams the confidence to ship.
API design and platform engineering
APIs treated as products, with clear contracts, consistent behavior, and an experience designed for the person consuming them.
Security engineering
Threat modeling integrated into design. Defense in depth through architecture. Security as part of how the system is built, not something checked at the end.
How We Work
Three phases, no magic
Our engineering lifecycle is straightforward. We invest time understanding the problem, build in short cycles, and maintain systems as they evolve.
Discovery
We invest time in understanding the problem before committing to a direction. This means talking to users, studying the domain, and mapping technical constraints. Discovery prevents expensive mistakes later.
Build
We build in short cycles, delivering working software that can be reviewed and tested by real people. Every iteration is deployable. We pair with client engineering teams wherever possible.
Maintain
A system is not done when it launches. We provide ongoing support, monitor system health, and address technical debt before it compounds. Many of our longest relationships are in this phase.
Industry Experience
Sectors we know well
Every sector has its own constraints, regulations, and user expectations. We bring domain understanding alongside technical skill.
Financial services
Regulatory compliance, event sourcing, auditability
Industrial and manufacturing
OT/IT integration, operator-first interfaces
Healthcare and life sciences
Clinical workflows, compliance as design constraint
Consumer and retail
Scalability, performance, checkout reliability
Energy and resources
Real-time monitoring, intermittent connectivity
Public sector
Accessibility, iterative delivery, citizen-facing services
Our Position
Stability, clarity, utility
These are not slogans. They are the three tests we apply to every technical decision we make.
Stability
We use technologies that have been tested in production by thousands of teams. We are suspicious of trends. PostgreSQL, well-structured HTTP APIs, and straightforward deployment pipelines solve most problems well.
Clarity
Code is read more than it is written. We name things carefully, document decisions, and structure systems so that a new team member can understand them within days, not months.
Utility
Software that nobody wants to use is not a success, regardless of how elegant the architecture is. We talk to users, watch how they work, and measure whether our systems actually help them.
Client Feedback
What our clients say
"Vista 360 helped us modernize a legacy system that had been holding us back for years. They took the time to understand our domain before writing a single line of code. The result was a reliable, well-documented platform our team can maintain confidently."
VP of Engineering
Financial Services Company
"Their cloud architecture work cut our infrastructure costs by 40% while improving reliability. What impressed us most was their disciplined approach -- every decision was documented, every trade-off explained clearly."
CTO
Healthcare Technology Company
"We brought Vista 360 in to rebuild our data pipeline. They delivered on time, within budget, and left us with a system our analysts actually enjoy using. The quality of their engineering is exceptional."

FAQ
Frequently asked questions
We work with organizations ranging from funded startups to large enterprises. What matters is not size but whether you have a real engineering challenge and a willingness to invest in doing it properly.
Both. Some clients need a full team embedded for months, others need focused help on a specific problem. We structure engagements around what the work actually requires.
We document as we go -- architecture decisions, runbooks, deployment procedures. We also pair with your engineers regularly so knowledge is shared continuously, not dumped at the end.
We are strong in PostgreSQL, TypeScript, Python, cloud-native architectures on AWS and GCP, and modern frontend frameworks. But we choose tools based on the problem, not the other way around.
We typically work on a time-and-materials basis with clear scope boundaries. For well-defined projects, we can offer fixed-price engagements. We are transparent about costs from day one.
