What our Spring Boot
engineers own.
Spring Boot microservices
Well-structured services with clear bounded contexts and independent deployability.
Spring Security
OAuth2, JWT, SAML, and method-level authorization. Enterprise-grade identity.
JPA / Hibernate
High-performance data access layers tuned for production loads — no N+1 disasters.
Spring Batch
Large-scale batch processing for ETL, settlement, reporting, and regulatory workflows.
Spring Actuator
Health checks, metrics, and observability built in from day one.
Event-driven systems
Kafka, RabbitMQ, and Spring Cloud Stream for decoupled, scalable architectures.
Performance tuning
JVM tuning, GC configuration, and connection pool optimisation — measured.
Multi-module projects
Clean Maven/Gradle structures for codebases multiple teams work on safely.
// deep-verticals
Six verticals we know cold.
Banking & Financial Services
Core banking, payments, trading, and settlement systems that cannot go down.
Insurance
Policy administration, claims, underwriting, and actuarial systems.
Government & Public Sector
National registries, tax systems, and citizen-facing platforms.
Telecommunications
Billing, provisioning, OSS/BSS, and network management systems.
Manufacturing & Logistics
MES, WMS, ERP integrations, and supply-chain orchestration.
Healthcare
Patient records, clinical systems, and HIPAA-aligned platforms.
// why-spring
Why enterprises
choose Spring Boot.
Two decades of stability
Spring has been the enterprise Java standard since 2003. Your investment is protected for 20+ years, not 3.
Enterprise hiring pool
Java developers are the largest professional developer community in the world. Growth is easy.
Production at every scale
From regional banks to global payment networks — Spring runs the systems that can't fail.
Compliance by default
Audit logging, transaction management, and RBAC are built into the framework.
Predictable performance
The JVM's mature tooling means performance is measurable and tunable, not guesswork.
Cloud-native ready
Spring Cloud, Native images, and Kubernetes integration — modern without being trendy.
// spring-ecosystem
Six projects in the Spring family.
Spring Boot is the entry point. These are the projects every senior engineer on our bench knows.
Spring Boot
Application framework. Auto-configuration, embedded servers, production-ready defaults.
Spring Cloud
Service discovery, config server, circuit breakers, and gateway for distributed systems.
Spring Security
Authentication, authorization, OAuth2, JWT, SAML. Enterprise identity done right.
Spring Data
Repository abstractions for JPA, MongoDB, Redis, Elasticsearch, and more.
Spring Batch
Batch processing for settlement, ETL, and regulatory reporting at scale.
Spring Actuator
Production endpoints for health, metrics, env, and thread dumps.
// jvm-tuning
Six flags every senior
engineer defends.
Not cargo-culted from a blog post. Each of these is a decision — with a specific reason and a specific tradeoff.
jvm flags we defend
6 flags-XX:+UseG1GC
Default for most services. Predictable pause times at heap sizes up to ~16 GB.
-XX:MaxGCPauseMillis=200
Soft target for pause time. Tune for latency-sensitive endpoints.
-XX:+UseZGC
Sub-millisecond pauses. Use for heaps over 32 GB or strict latency SLAs.
-Xms2g -Xmx2g
Same min and max heap. Prevents resize-induced pauses during ramp-up.
-XX:+HeapDumpOnOutOfMemoryError
Always on. Post-mortem debugging saves hours.
-XX:MaxRAMPercentage=75
Container-aware heap sizing. Respects the container limit, not the host.
// migration-playbook
Spring Boot 2 → 3.
The Jakarta migration.
Five phases. Every service migrated independently, tested against parallel runs, rolled back without drama.
Inventory
Audit dependencies. Flag javax.* imports, deprecated APIs, and libraries with no Jakarta-ready release.
Jakarta namespace
Mechanical javax.* → jakarta.* rename via OpenRewrite. Version bumps per module.
Security config
Spring Security 5 → 6 rewrite. Lambda DSL, deprecated APIs removed, method security reviewed.
Parallel test
Run the test suite against Boot 3. Fix regressions per module. Snapshot JVM metrics before/after.
Cutover
Roll out service by service. Rollback plan per service. Monitor JVM, GC, and error rates for 72 hours.
// tech-stack
The tools our Spring engineers master.
// also fluent in
// guarantees
Six things, in writing.
No exceptions.
2-week paid trial
Work with your engineer for two weeks. If it's not right, no obligation.
Free replacement
Within 30 days if the fit isn't right. Same vetting bar, same standard.
NDA before specifics
Signed before any project details change hands.
Full IP assignment
You own every line we write. No licensing, no reuse clauses.
30-day cancel
No termination fees, no lock-in. Stop the engagement whenever you need to.
Vetted bench
Technical, code, communication, and reference checks before you see a candidate.

2-week paid trial. Convert to full engagement if it works.
// why-us
Skip the CV pile.
Get real engineers.
Anyone can post a job ad. We do the vetting, reference checks, and technical screening — so you only see candidates worth interviewing.
Vetted, not listed
Every engineer passes all four filters before you see them.
Available in days
Most roles placed within 5–10 business days.
Long-term placements

Global-ready
Overlap with African, European, and NA time zones.
Client feedback
What our clients
actually say.
“The move to SikaNet CBS was a bigger shift than I expected — but the right one. Before, our Susu collectors were on paper and every BOG report took us days to assemble. Now collections appear in the office before a collector even finishes their route, and the reports are just there. The team understood our business from day one.”
David Awuni
Founder, Adwumapa Microfinance
“We were cautious about moving patient records online. The on-prem approach changed that — everything stays inside the health center, nothing goes to a foreign cloud. Our clinicians now retrieve a file in seconds instead of ten minutes, and every entry has an audit trail behind it.”
Medical Director
Sekyedumase Health Center
“The patient management system they developed has streamlined our ophthalmology department. Appointment scheduling, patient records, and referral tracking are now seamless — saving us hours of administrative work every day.”
Isaac Adu
Ophthalmologist, Ghana Health Service
