AI-assisted development
Introduced BMAD-inspired workflows for requirements, architecture, task decomposition, implementation, review, and validation.
Lead Engineering Manager | Software Consultant | Sri Lanka
I connect backend architecture, cloud operations, AI-assisted development, and delivery planning so teams can ship software that is practical to maintain, clear in purpose, and ready for real business pressure.
About
Buddhi brings software engineering experience across banking, finance, real estate, automobile data, charity, retail, and product experiments. His work centers on backend systems, API design, database development, CI/CD, cloud operations, AI-assisted delivery practices, and shaping requirements into delivery plans that make sense for clients, users, and engineering teams.
Current Focus
At Helagen, my focus is helping teams build enterprise software, business apps, and websites with stronger architecture, delivery structure, and platform reliability.
Introduced BMAD-inspired workflows for requirements, architecture, task decomposition, implementation, review, and validation.
Mentoring engineers on prompt engineering, context engineering, agent workflows, debugging, refactoring, and code quality.
Translating business and product requirements into roadmaps, system designs, delivery plans, and engineering priorities.
Engineering Approach
I approach products from the engineering system outward: what needs to be reliable, what the data needs to prove, and where the team needs structure before complexity becomes rework.
Start with business goals, edge cases, roles, and operational pressure before choosing the technical path.
Make permissions, errors, audit trails, exports, and deployment paths reliable enough for production use.
Use spec-driven, AI-assisted workflows to connect requirements, architecture, tasks, implementation, and validation.
Stack
ASP.NET Core, C#, .NET APIs, Azure Functions, background workers, MS Graph integrations.
Azure, Azure DevOps, Azure Kubernetes Service, Google Cloud VMs, CI/CD, server setup.
MS SQL Server, PostgreSQL, API persistence models, reporting exports, audit trails.
Angular, React, product discovery, business workflows, delivery planning, client communication.
Spec-driven development, BMAD-inspired workflows, prompt/context engineering, AI-assisted debugging, review, and validation.
Leadership
Review work, unblock technical issues, and improve engineering practices through practical feedback and shared context.
Turn requirements into architecture, milestones, implementation paths, and validation checks teams can execute against.
Support recruitment, onboarding, knowledge sharing, and capability development across the engineering function.
Experience
Leading engineering delivery across enterprise software, business apps, websites, architecture, platform reliability, and AI-first development practices.
Led technical delivery across API, database, Azure, and product workflow decisions for a global real estate client, with a focus on maintainable implementation and reliable delivery.
Designed and developed APIs and databases for a global real estate company using ASP.NET Core, C#, MS SQL, Azure, Azure Functions, and Angular.
Guided delivery for a small engineering team on a global investment research platform, managed client requirements, supported recruitment and training, and administered CI/CD through Azure DevOps and Azure Portal.
Built APIs and databases for investment research, maintained legacy ASP.NET systems, integrated Open Banking APIs, and worked across Azure Kubernetes Service, PostgreSQL, MS SQL, C#, and Angular.
Contributed to research, design, and development of projects including web scrapers, Discord bots, Telegram bots, and client software using C#, Python, SQL Server, and JavaScript.
Built C#, HTML Agility Pack, and Selenium screen scrapers for OEM dealer and crime data, tested CRM products, and contributed updates through daily Scrum reporting.
