10+ production systems • Spring, Kotlin, Kafka

Java Enterprise

A Java backend that holds the load and doesn't wake you at 3 a.m. — even when traffic grows 10×

We design microservices, integrations and legacy-monolith migrations. 99.95% SLA, documentation, tests, and training for your team.

Problems we solve

Sound familiar?

Java lives for decades — and accumulates problems for decades that slow the business down.

A monolith that won't release

Every release is a night shift for a team of ten and a prayer.

Incidents nobody can explain

Because there are no logs, monitoring is Zabbix from 2014, and there is no architecture documentation at all.

Knowledge walks out with the team

Seniors leave — and the codebase becomes a black box for new engineers.

Cloud costs as much as the office

Because the architecture hasn't changed since on-prem days — it just moved to AWS.

How we help

Java systems that you can actually maintain

Clean architecture, documentation, tests, monitoring — and a team that transfers knowledge rather than hoarding it.

Architecture for your domain

DDD, hexagonal or layered — we pick what fits your business, not what's trendy.

Observability out of the box

Metrics, traces, logs with correlation — incidents found in minutes, not days.

Tests that actually catch regressions

Unit + integration + contract. CI catches them, not your customers.

Knowledge transfer

Onboarding doc for new engineers, ADRs for every decision, pair programming with your team.

What you get

Not 'GitHub access' — a working system

  • Microservices or a modular monolith in production with CI/CD
  • API documentation (OpenAPI / GraphQL schema)
  • Architectural decisions recorded as ADRs
  • Monitoring, alerts and dashboards (Prometheus / Grafana)
  • Tests: unit, integration, contract, load
  • Onboarding document for new developers

Process

From idea to production — in 8–16 weeks

01

Discovery (2 weeks)

Analysis of the business domain, current systems, load and SLA requirements.

02

Architecture (1–2 weeks)

Service decomposition, integration map, migration plan, risk assessment.

03

Build (4–10 weeks)

Two-week sprints. Every module goes to staging with automated and load tests.

04

Launch & Support

Phased rollout, monitoring, on-call support (8/5 or 24/7).
