Senior by default
Every engagement is led by architects and lead developers — not staffed up with juniors learning on your budget. The senior who scopes your project is the one who builds it.
Hello World Tech Consulting LLP is a senior team of Java, Spring Boot and cloud architects — 14 to 20 years of experience each. We build and modernise mission-critical backend systems — event-driven, AI-native and engineered to scale — for clients in the US, UK, Europe and Australia.
We started Hello World to do one thing exceptionally well: build and modernise enterprise backend systems. That focus has held. We design Spring Boot microservices that are modular and maintainable, apply Spring AI to power GPT- and LLM-driven workflows, and run Kafka-based event-driven systems in production on AWS and GCP. Whatever your backend requirement — application development, modernisation, resourcing or support — we have an offering for you.
