Every engagement is led by architects and lead developers — not staffed up with juniors learning on your budget.
About Us
Engineering software, the way it should be built.
Hello World Tech Consulting LLP is a senior team of Java, Spring Boot and cloud architects. For 16+ years we've built and modernised mission-critical backend systems — event-driven, AI-native and engineered to scale.
01 Our Story
A consultancy built around engineering depth
We started Hello World to do one thing exceptionally well: build and modernise enterprise backend systems. Over 5+ years and 20+ projects, 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 IT requirement — application development, resourcing, training or support — we have an offering for you.
