Lead Engineering Manager | Software Consultant | Sri Lanka

Engineering leadership for reliable cloud products.

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

A practical engineering leader who cares how software behaves after the handoff.

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

Leading AI-first engineering without losing software discipline.

At Helagen, my focus is helping teams build enterprise software, business apps, and websites with stronger architecture, delivery structure, and platform reliability.

AI-assisted development

Introduced BMAD-inspired workflows for requirements, architecture, task decomposition, implementation, review, and validation.

Engineering enablement

Mentoring engineers on prompt engineering, context engineering, agent workflows, debugging, refactoring, and code quality.

Product to execution

Translating business and product requirements into roadmaps, system designs, delivery plans, and engineering priorities.

Engineering Approach

Good delivery starts with clear requirements, architecture, and validation.

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.

01

Clarify the real problem

Start with business goals, edge cases, roles, and operational pressure before choosing the technical path.

02

Build for confidence

Make permissions, errors, audit trails, exports, and deployment paths reliable enough for production use.

03

Structure the delivery

Use spec-driven, AI-assisted workflows to connect requirements, architecture, tasks, implementation, and validation.

Stack

Tools used to ship and support production systems.

Backend

ASP.NET Core, C#, .NET APIs, Azure Functions, background workers, MS Graph integrations.

Cloud & DevOps

Azure, Azure DevOps, Azure Kubernetes Service, Google Cloud VMs, CI/CD, server setup.

Data

AI-assisted Delivery

Spec-driven development, BMAD-inspired workflows, prompt/context engineering, AI-assisted debugging, review, and validation.

Leadership

How I support engineering teams.

Mentor and unblock

Review work, unblock technical issues, and improve engineering practices through practical feedback and shared context.

Shape delivery plans

Turn requirements into architecture, milestones, implementation paths, and validation checks teams can execute against.

Grow team capability

Support recruitment, onboarding, knowledge sharing, and capability development across the engineering function.

Experience

Professional timeline.
