I'm a passionate Software Engineer who builds optimized, scalable, and maintainable solutions using cutting-edge technologies. With a strong foundation in both front-end and back-end development, I bring full-stack capabilities that drive entire projects from concept to deployment.

I thrive in dynamic environments where flexibility and adaptability are key. Whether it's refining existing systems or architecting new platforms, I enjoy embracing challenges and solving complex problems through clean, performant code. I'm experienced across the full lifecycle of software development—from planning and design to development, deployment, and beyond.

Experience

2024 March - Current
Software Engineer
Neura Intelligence
As a full-stack developer, I optimized React.js applications through code splitting, seamless TypeScript integration, and reusable component architecture to improve performance and maintain high code quality. On the backend, I streamlined operations by building efficient database pipelines and integrating advanced search capabilities. I engineered low-latency speech-to-text systems using FastAPI and enhanced the frontend user experience with infinite scroll functionality. Additionally, I mentored fellow developers on best practices, fostering team-wide efficiency and ensuring scalable, maintainable architectures across projects.

Associate Software Engineer
Neura Intelligence
I built robust, production-ready systems as a full-stack developer, including dual-protocol AWS S3 upload workflows designed to minimize failure rates and GPT-4 integrations that powered intelligent, context-aware chat interactions. I modernized mobile-first user interfaces with SCSS and Bootstrap to ensure seamless performance across devices, and I implemented secure, token-based authentication using JWT and AWS Cognito for protected dashboards. I focused on enhancing accessibility by integrating React Context-based features such as selected content playback, along with AI-powered reference highlighting that improved usability and content clarity for diverse users.

Education

2020 - 2024

BSc (Hons) in Information Technology, Specializing in Software Engineering

Sri Lanka Institute of Information Technology (SLIIT)

Colombo, Sri Lanka

During my studies, I focused on object-oriented programming with Java and Python, where I applied SOLID principles and design patterns to build clean and maintainable code. I studied software development life cycles and Agile methodologies, gaining hands-on experience with both relational and NoSQL databases, as well as distributed systems. I developed full-stack applications using technologies like React Native and JSP, and I built RESTful APIs while optimizing backend systems through ACID-compliant data models and query tuning. I also participated in Scrum-based projects, created UML diagrams to model software architecture, and conducted quality assurance testing. Throughout my education, I took on leadership roles in team projects and practiced clear, client-oriented communication to deliver reliable and scalable software solutions.

Mastered Object-Oriented Programming (OOP) principles like inheritance, encapsulation, and polymorphism, applied in Java, C++, Python, and JavaScript to build modular and reusable code for projects ranging from system utilities to web apps.

Designed and optimized relational databases using SQL (MySQL, PostgreSQL) and NoSQL (MongoDB) systems, balancing trade-offs with ACID compliance and CAP theorem for scalable, fault-tolerant solutions.

Built cross-platform mobile apps with React Native, focusing on responsive UIs and seamless integration with backend services.

Led Agile/Scrum teams to deliver iterative software projects, prioritizing tasks with tools like Jira/ Azure boards and mastering SDLC phases (requirements, design, testing, deployment).

Applied SOLID principles and design patterns (Singleton, Factory, Observer) to write clean, maintainable code and solve recurring architectural challenges.

Crafted user-centric UI/UX designs with wireframing tools and accessibility standards, bridging frontend (React, JSP) and backend (Node.js, Express) in full-stack projects.

Modeled software workflows using UML diagrams (class, sequence, activity) and designed scalable architectures like microservices and MVC.

Managed distributed systems concepts, including fault tolerance, load balancing, and consensus algorithms (e.g., Paxos), for high-availability applications.

Optimized performance with data structures (trees, graphs) and algorithms (sorting, dynamic programming), solving problems efficiently for large datasets.

Adhered to ethical practices in tech, focusing on data privacy, intellectual property, and teamwork dynamics in professional environments.

Automated workflows with Python scripts and analyzed trends using statistical methods (hypothesis testing, regression).

Configured computer networks and managed OS-level tasks like process scheduling, memory allocation, and system administration.
