Where Java fits

Java is still the default when you want predictable operations: strong libraries, mature observability, and teams that can maintain a product for years. We use it heavily for B2B services, integrations, and long‑horizon enterprise work.

• Spring Boot — REST and messaging services, batch jobs, integration with ERP/CRM and payment rails.
• Service boundaries — clear module ownership, contract tests, versioned APIs for partners.
• Android / JVM adjacency — shared API contracts and release trains when mobile and backend must move together.

Greenfield vs maintaining a Java estate

New services need baseline decisions: security model, observability, database migrations, deployment topology — so the first milestones cost more than “steady state.” Maintenance on a healthy codebase is usually a predictable monthly burn: tickets, releases, dependency upgrades, and incremental features — spikes only when you modernise frameworks or split monoliths.

Capacity: junior vs senior

Java rewards strong mid-level execution under senior review for anything touching money, identity, or data contracts. A common pattern: 1 senior tech lead (part-time to full-time) plus 2–4 mid engineers for sustained delivery; juniors help on tests, internal tooling, and smaller endpoints once patterns are fixed.

Representative delivery (summary)

Across programmes we have operated integration-heavy backends and Angular-facing admin stacks where Java services feed dashboards for operations teams — the emphasis is on reliable monthly releases and audit-friendly behaviour, not throwaway demos.

Cost expectations

Software is priced by milestone after discovery (USD) — software tiers. Employed staff align with India ops retainers — see pricing. For planning, many Java programmes sit in the mid four-figures to five figures USD per month range once a team is running; greenfield platform work is usually phased so cost follows de-risked releases.
