Best fit
Best for B2B SaaS and internal product teams with legacy backend or admin UX risk.
Best fit
- B2B SaaS product teams
- Internal operations product owners
- Operations-heavy software products with brittle admin tooling
- Companies with aging Java/Spring backends
- Teams that need staged migration before considering a rewrite
Not a fit
- Cheap brochure website projects with no product or modernization scope
- Teams looking for a large agency with multiple account layers
- One-off AI trend experiments without a legacy stack problem to solve
- Infrastructure-only networking work with no product engineering ownership
- Blind fixed quotes before an audit or technical discovery pass

FAQ
Common modernization questions.
General Can you modernize without stopping releases?
Yes. Engagements are scoped in staged sprint slices so releases can continue while higher-risk areas are isolated and improved.
General Do you work with monoliths and older Spring Boot versions?
Yes. The audit starts with version risk, module boundaries, and upgrade blockers so the first sprint targets the safest modernization path.
General Can you help before a full rewrite decision is made?
Yes. Audit-first work is designed to clarify whether staged refactoring, modular extraction, or a deeper rewrite is actually justified.
General Do you work with in-house or offshore engineering teams?
Yes. Delivery is founder-led and works well alongside existing product, QA, and engineering teams with planned overlap and async updates.
General What does the modernization audit include?
Typical outputs include dependency risk notes, API contract review, admin workflow bottlenecks, phased migration priorities, and a recommended first sprint.
General What budget range is typical?
Most focused modernization sprints start from the low five figures in USD, depending on stack age, integration risk, and rollout complexity.
