Project details
Get a senior-level review of your generative AI application—not a generic automated code scan.
I bring over 19 years of software-development experience across enterprise applications, backend systems, distributed architecture, cloud platforms, data integration, banking, insurance, and production support. I work across C#/.NET, Java, Python, SQL, JavaScript/TypeScript, APIs, databases, event-driven systems, and AI-enabled applications.
I will review the agreed application scope, including its architecture, source code, AI model integration, prompts, APIs, data flow, database usage, error handling, security, testing, monitoring, performance, reliability, scalability, and maintainability.
You will receive clear, prioritised findings and practical recommendations aligned with your application’s business purpose and technical constraints. Depending on your package, the delivery may also include detailed code comments, a structured improvement roadmap, and a consultation to discuss the results.
Please message me before ordering if your application contains multiple repositories, microservices, complex infrastructure, sensitive data, or a large codebase.

About Vimal - Thavarajah
Hands-On Software developer | Architect ***NEW To UpWork
Bournemouth, United Kingdom - 9:42 pm local time
I’m a UK-based Senior Software Engineer and Technical Lead with 19+ years of experience designing, developing, modernising, and supporting business-critical software.
My expertise spans C#/.NET, Java, Python, SQL, cloud technologies, APIs, data integration, distributed systems, event-driven architecture, and AI-enabled application development. I’m not limited to a particular technology stack: I focus on understanding the business problem and selecting a practical, reliable, secure, and maintainable solution.
My areas of experience include:
• Backend and enterprise application development
• Application architecture and technical design
• Legacy-system modernisation and migration
• REST APIs, microservices, and system integration
• SQL, database design, ETL, and data migration
• Distributed and event-driven systems, including Kafka
• Performance optimisation and technical troubleshooting
• Cloud deployment, DevOps, and CI/CD
• AI, Large Language Models (LLMs), and generative AI integration
• Retrieval-Augmented Generation (RAG) applications
• Code reviews, technical guidance, and team leadership
• Production support for business-critical applications
I am currently working with modern AI technologies, including LLM-powered applications, Retrieval-Augmented Generation, prompt design, document and knowledge retrieval, embeddings, vector-based search, and the integration of AI models with existing applications, APIs, databases, and business workflows.
My focus is on applying AI to real business problems rather than using it as a standalone novelty. This includes exploring solutions such as intelligent knowledge assistants, document-search systems, contextual question-answering tools, workflow automation, information extraction, summarisation, and AI-assisted decision support. I can help evaluate where an LLM or RAG solution is appropriate, design the supporting architecture, build a proof of concept, and integrate it into an existing software environment.
Much of my career has been within financial services, including investment banking, private banking, treasury management, foreign-exchange trading, risk systems, and general insurance. I have contributed to high-volume trading platforms, near-real-time risk applications, cloud-based treasury products, data-processing systems, enterprise portals, and complex integrations.
I currently work with a US-based financial software company, developing a cloud-based treasury-management product for hedge funds, private markets, and banks. Previously, I spent approximately 14 years working in Singapore and two years in Sri Lanka, contributing to and leading enterprise software projects for major banking, insurance, technology, and government organisations.
Throughout my career, I have worked across the complete software-development lifecycle: requirements analysis, architecture, technology selection, development, testing, integration, deployment, production rollout, performance optimisation, and ongoing support. I have also led development teams, worked closely with business stakeholders, and translated complex operational requirements into dependable technical solutions.
I hold a Master of Technology in Software Engineering from the National University of Singapore.
I can work independently as a hands-on senior developer or bring in a trusted development team for larger engagements when required. Whether you need a new application, an existing system modernised, a difficult production issue resolved, a data or API integration, or an AI-powered solution, I can provide both strategic technical direction and hands-on implementation.
If you need an experienced technical partner who can understand complex requirements, communicate clearly, and turn business challenges into well-engineered software, let’s discuss your project.
