Suo Systems

Independent software engineer · Remote contract work

Fix, extend, and stabilize the software your business already relies on.

I help businesses and product teams resolve production issues, take over existing systems, repair unreliable integrations, and safely deliver well-defined changes to software already in use.

Best fit: existing SaaS products, internal tools, and legacy applications with customers, data, or business-critical workflows already depending on them.

Capabilities

Technical depth for the parts of a system that need to keep working.

The tools are chosen to fit the system in front of us—not to force a rewrite or a preferred stack.

01Backend

Existing application development

PHP, Java, Go, and Node.js work across existing business logic, background jobs, data flows, and deployment paths.

02Web

Product and internal-tool features

JavaScript, TypeScript, and modern frontend frameworks for clear, maintainable changes to established products.

03Systems

Integrations and operations

APIs, CRM and payment connections, databases, logs, retries, monitoring signals, and safer releases.

The reality

When existing software becomes the problem

Working software can still hold a business back. Risks accumulate, people move on, and the next change becomes harder to make safely.

01Revenue at risk

A production bug is affecting customers or revenue

The issue is visible, urgent, or costly to leave unresolved.

02No owner

A previous developer is no longer available

Ownership and system knowledge have quietly disappeared.

03Unsafe to change

A legacy system is too risky to change

Even useful improvements feel unsafe without a careful path.

04Silent failure

An API integration is failing silently

Data stops moving and the business notices too late.

05Blocked delivery

A needed feature is blocked by an unfamiliar codebase

The product has a clear need, but no dependable delivery path.

06Demo only

An AI-built app works in a demo but is not safe for production

The code needs a practical review before it becomes business-critical.

Engagements

Ways we can work together.

Bring a clear problem or outcome. I will help define the safest useful scope and delivery path.

01Urgent

Production fixes and technical rescue

For live defects, failed integrations, or systems that need a dependable engineer to investigate and stabilize them.

02Defined scope

Feature and integration sprints

For a well-defined capability, workflow, or third-party connection that needs to fit safely into an existing product.

03Ongoing

Maintenance and technical ownership

For teams that need steady help maintaining, improving, and making sense of a business-critical application.

Services

What I help with

Focused technical work for systems that already matter to the business.

01

Production Bug Fixes & Software Rescue

Find the cause of a live issue and make a safe, testable correction in software already serving users.

Reproduce · root cause · safe release
02

Legacy PHP & Java Modernization

Reduce risk in an older application through staged runtime, dependency, and maintainability improvements.

Incremental upgrades, not rewrites
03

API Integrations & Custom Development

Make business systems exchange data reliably, with observable failure paths and practical recovery behaviour.

Retries · audit logs · observability
04

Custom Feature Development

Add a well-defined capability to an existing SaaS product or internal tool without destabilizing what already works.

Scoped, tested, documented
05

AI-Built App Hardening

Turn a promising AI-built or contractor-built prototype into a system that can be operated and maintained responsibly.

Auth · migrations · deployment
06

Taking Over an Abandoned Codebase

Create a safe path into software whose original developer, agency, or technical partner is no longer available.
