End-to-end web applications — from component-level UI through API design to database and deployment. Production features shipped with tests, CI, and monitoring.
→React Native applications with native-feeling interactions, robust state management, and streamlined App Store and Play Store delivery.
→Services designed for load — microservices, message queues, CI/CD pipelines, and observability built in from the start rather than bolted on later.
→Codebase audits, technical-debt triage, and guidance on stack choices, performance, and engineering quality — for individual teams or full organisations.
→The GCC's first unified logistics platform — multi-carrier management, fleet mobility, warehousing, and cross-border operations on a high-availability microservices backbone.
A cardiology clinic platform — appointment booking, patient education, and a calm, trustworthy interface tuned for a high-stakes medical context.
A SaaS billing platform covering dashboard analytics, invoice lifecycle, and role-based access — complex table UIs and financial data visualisation built in React and Node.
REST APIs and microservices powering multiple Zapmii products — SonarQube-gated quality, Dockerised deployments, and Jenkins CI/CD for reliable releases.
My SLIIT research capstone — automated grading, engagement tracking, auto-whiteboard capture, and CNN-based attendance, with measured impact on teaching strategies and student comprehension.
Mobile companion apps for field teams at Aarthy HqC — React Native front-end over REST APIs and a Laravel back-end, with a focus on cross-device consistency and offline resilience.
Leading the design and development of core components in RedexGo, the GCC's first unified logistics platform — multi-carrier management, fleet mobility, warehousing, and cross-border operations across the GCC and Sri Lanka. Architecting end-to-end features, building high-availability APIs and microservices, leading code reviews, and driving continuous improvement.
Led development and maintenance of scalable web apps using React, Node, and TypeScript. Designed REST architecture with emphasis on performance and security, deployed via AWS with Jenkins-managed CI/CD, mentored juniors, and contributed to technical direction and product innovation.
Designed and developed full-stack apps with Node, TypeScript, Express, and React. Built REST APIs and microservices, optimised state management and load times, handled AWS deployment and monitoring, and enforced quality through SonarQube and Docker pipelines.
Built scalable web apps with TypeScript, React (Hooks), Redux, and SASS. Designed and consumed REST APIs, automated CI/CD with Jenkins and Docker, and operated in an Agile environment with Jira — sprint planning, backlog refinement, and task tracking.
Contributed to MERN-stack applications — dynamic UIs with React Hooks and TypeScript, REST APIs, Docker containerisation, and code analysis via SonarQube. First step into full-stack delivery at scale.
Built responsive apps with React, ES6+, and modern front-end libraries. Translated UI/UX wireframes into functional interfaces, integrated REST APIs with back-end developers, and improved performance via Redux and Context-API state management.
First industry role. Collaborated on front-end frameworks (React, React Native), implemented REST APIs and third-party integrations, contributed to MySQL schema work, and worked closely with QA in Agile/Scrum ceremonies.
Four years of engineering fundamentals — algorithms, distributed systems, databases, and HCI — capped by a research capstone on LECTA: a deep-learning-powered educational platform for automated grading, engagement tracking, and auto-whiteboard attendance.
I've had the pleasure of working with him for over two years. He's an exceptional project lead who brings a strong focus on detail and quality. He consistently goes beyond surface-level requirements to address the finer points of development — projects are not only delivered effectively but are also maintainable and scalable long-term.
Theebanraj is a highly dedicated and hardworking individual with strong expertise in the MERN stack. Whether it's front-end UI or back-end architecture, he delivers with excellence and reliability.
He joined as a fresh graduate on a microservice-based system with multiple services in Node and React. Within a short time he ramped up to work as a full-time dedicated engineer with minimal supervision.
Working with Theebanraj across multiple cloud and web projects has been a rewarding experience. Technically strong, detail-oriented, and consistently delivers high-quality solutions. A dependable and skilled teammate.
I worked with Theebanraj for almost a year and saw how great he is both in a team and when leading something on his own. Responsible, easy to work with, and always brings good vibes — you can count on him.
Theeban is a knowledgeable individual who can work flexible hours. He's a fast learner and capable of solving complex problems with simple solutions.
