Why Timely Coders

Spring Boot done right with architecture, resilience, and speed

Modernization without downtime
Swap legacy parts while the app stays online. We carve out pieces gradually, turn them on with feature toggles, and keep old and new in sync with event streams.
Performance engineering
Find and fix bottlenecks, tune database and thread pools, add caching where it counts, and keep the system responsive under heavy use.
Resilience by design
Built to handle failure: isolate services, stop errors from spreading, retry safely, and design APIs that are safe to call more than once.
Clean code & contracts
Agree on clear API contracts (OpenAPI) before we build. Use a clean, testable architecture and tidy data mapping so changes stay easy.
Production-grade CI/CD
Every change is built, tested, and security-scanned automatically. We keep a software inventory (SBOM) and roll out gradually with fast rollbacks.
Compliance ready
Know who did what and when, collect only necessary personal data (PII), support data processing agreements (DPA), and follow clear data retention rules.

Patterns

Battle-tested solution templates

API Platform

  • OpenAPI-first
  • JWT & scopes
  • Rate limits & quotas
  • Canary & shadow traffic

Event-driven

  • Kafka topics & schemas
  • Outbox pattern
  • Exactly-once semantics (idempotency)
  • Stream processors

Batch & ETL

  • Spring Batch
  • S3/GCS staging
  • Retry & dead-letter
  • Observability & alerts

Real-time

  • WebFlux & R2DBC
  • Back-pressure
  • Reactive gateways
  • Async boundaries

Monolith → Services

  • Strangler fig
  • Domain decomposition
  • Shared-nothing data
  • Zero-downtime cutovers

Edge & Gateways

  • Spring Cloud Gateway
  • AuthZ policies
  • Circuit & fail-fast
  • Request shaping
Engineering

What we bring to every service

Security
  • OAuth2/OIDC, PKCE, mTLS between services
  • Keycloak/Okta integration, fine-grained scopes
  • Secrets mgmt (Vault/Secrets), SBOM & SCA in CI
Performance
  • HikariCP pools, proper timeouts, GC tuning
  • Spring Cache with Redis, near-cache patterns
  • AOT/native images where it pays off
Resilience
  • Resilience4j: retries, circuit, bulkhead, rate limit
  • Idempotent handlers & dedupe keys
  • Fallbacks & graceful degradation
Observability
  • Micrometer + Prometheus/Grafana dashboards
  • OpenTelemetry traces/logs/metrics correlation
  • Error budgets & SLO alerting
Data
  • JPA/Hibernate, Flyway/Liquibase migrations
  • R2DBC for reactive IO, read replicas & CQRS
  • Redis, Postgres, MySQL, MongoDB
Testing & QA
  • JUnit 5, Testcontainers, WireMock
  • Contract tests & consumer-driven contracts
  • Load tests & chaos experiments

What Clients Say

Proof from the field

“They carved our monolith into stable services without outages. SLOs and dashboards gave us control.”

- CTO, Fintech scale-up

“Security & compliance were never afterthoughts-Keycloak, policies, and audit were built in from day one.”

- Head of Engineering, B2B SaaS
FAQ

Hiring FAQs

You get virtual threads, improved GC, and a modern Spring stack with native image support. Faster, more efficient services.

When IO-bound, streaming, or high concurrency: yes. Otherwise, we keep it simple with MVC. We pick per use-case.

12-factor apps, portable containers, infra as code, and standards (OpenAPI/Otel). No proprietary glue.

We use Flyway/Liquibase, feature flags, and backfills with verification to ship safely without downtime.
