Obiz Solutions

Services

I take on custom software and system-building work — from simple websites through to complex platforms on the Java enterprise stack, and especially deploying them onto cloud infrastructure. 20+ years building and operating production systems for aviation, banking, media, and e-commerce clients, either as a solo end-to-end contractor or as a principal developer / architect inside a distributed team.

Websites & web applications

From a simple marketing site to a full e-commerce platform or customer portal — built to load fast and stay cheap to run.

Astro · Spring Boot · Vue.js / AngularJS · REST APIs

Java enterprise systems

Production backends with a clean, layered architecture (controller → service → repository), secured endpoints, a modelled relational schema, and JUnit coverage from day one.

Java 8–21 · Spring Boot · Spring Security · Spring Data JPA / Hibernate

Microservices & system design

Splitting a monolith or designing a new platform: service boundaries, identity and access, API contracts, and load testing before it reaches production.

Microservices · Keycloak / OAuth2 · Apigee · JMeter

Cloud deployment & DevOps

Getting a system onto the cloud and keeping it there — infrastructure as code, automated build/deploy pipelines, and Linux server administration.

AWS (EC2, Lambda, S3, API Gateway) · Terraform · Jenkins / GitLab CI/CD · Docker

API integration

Connecting systems to partner and third-party APIs — integration workflows, API proxies, and developer portals for governed, secure exposure.

REST · Apigee · OAuth2 · Webhooks

Legacy modernization

Moving an old system forward without breaking production: JDK upgrades, replacing manual releases with automated pipelines, and getting the team onto the new stack.

Java 1.6 → 11 / 21 · CI/CD migration · Refactoring · Test coverage

How I work

  • End-to-end: I can own a project across development, database, CI/CD, and the infrastructure it runs on — no dedicated support team required.
  • Embedded in a team: or work inside a distributed team across time zones as a principal developer or technical architect — SOW writing, system design, and code review.
  • Engagement: remote, part-time, and freelance.
