Software Engineer & Cyber Security Undergraduate

Dulith Divisekara

I architect systems and ship them fast: from serverless edge tooling to full-stack booking platforms.

Information Technology undergraduate specializing in full-stack systems, network/edge architecture, and automation. I combine CRUD architecture, MVC design, RESTful thinking, and Linux systems with modern AI-assisted development workflows to design, build, and deploy functional software at a pace traditional workflows can't match.

About

Systems Architect, AI-Augmented Builder

I treat AI-assisted development as a force multiplier, not a shortcut. I still design the architecture, define the data model, and own every technical decision; I just execute faster.

My work spans backend systems built from first principles, serverless edge deployment, and agentic infrastructure automation, proof that I can operate across the stack, not just prompt my way through one layer of it.

Formal training in the Model Context Protocol, the Claude API, and agent-skill design means I don't just use AI tools. I understand their architecture well enough to build with and around them.

Work

Featured Projects

Selected builds spanning full-stack systems, serverless edge compute, and agentic AI infrastructure.

Full-Stack Web Application

TixCore Event Booking System

A dependency-light event ticketing platform that gives admins full venue/event management and users a seamless booking flow, without requiring an external database server.

Java Spring Boot Thymeleaf Maven MVC CRUD

✓Modular System Architecture: a 6-module MVC system (Users, Admins, Venues, Events, Bookings, Reviews), each with full CRUD.
✓Custom Persistence Layer: a lightweight, pipe-delimited flat-file data store as a drop-in database replacement.
✓Deployment-Ready Packaging: portable runnable JAR via Maven, single-command deployment with zero external dependencies.

Knowledge Management System

SLIIT Y2S1 Vault

A version-controlled, AI-augmented knowledge base that transforms raw university lecture content across 4 modules into a structured, queryable, retention-optimized learning system.

Markdown Architecture Mermaid.js Git NotebookLM Obsidian

✓Structured Information Architecture: a hierarchical Markdown/frontmatter system compatible with graph-based tools like Obsidian.
✓AI-Augmented Documentation Workflow: LLM-powered study tooling embedding AI-generated quizzes and audio overviews per module.
✓Diagramming-as-Code: dynamically rendered Mermaid.js diagrams plus interactive flashcards for active recall.

Infrastructure Automation

Private Repo

Hermes Backup

A backup and restore pipeline. Kept in a private repository since it handles personal data, but happy to walk through the architecture on request.

Details on request

Interactive CLI / Serverless Tooling

Terminal CV

A programmatic, terminal-native resume served via serverless edge compute, replacing the static personal-website CV with a curl-executable developer experience.

Cloudflare Workers Serverless / Edge JavaScript HTTP Header Parsing

✓Edge-Native Deployment: resume delivery as a serverless function on Cloudflare's global edge network, with low-latency responses.
✓Dynamic Content Negotiation: request-header inspection to detect the client's platform and serve a tailored output format.
✓Differentiated Technical Branding: a curl-executable resume endpoint that signals fluency to a technical audience.

Agentic System State Management

Private Repo

OpenClaw Backup

An autonomous disaster-recovery pipeline for a personal AI agent, enabling full identity, skill-tree, and memory reconstruction on a fresh machine with a single command.

Bash System Automation AI Agent Architecture Security Hardening

✓One-Command Restoration Pipeline: a single script (restore.sh) that reconstructs an entire agent runtime after OS wipe or hardware failure.
✓Security-Conscious Backup Design: credentials stripped from the persisted state, enforcing "restore, then re-inject secrets."
✓Layered State Architecture: isolated directories for identity, capability, and history, transferable to DevOps and IaC practices.

Private Repository

Frontend Web Development

Personal Portfolio (Source Architecture)

A fully responsive single-page portfolio unifying networking, edge-computing, and embedded IoT project work into one cohesive, framework-light brand presence.

HTML5 Tailwind CSS JavaScript Cloudflare Edge Formspree

✓Framework-Light Responsive UI: semantic HTML5 and utility-first Tailwind CSS with vanilla JavaScript, no build tooling.
✓Integrated Contact Pipeline: a serverless contact-form flow via Formspree, cross-linked with the Terminal CV project.
✓Edge-Hosted Delivery: deployed to Cloudflare's Edge Network for global low-latency delivery.

Why Hire Me

"I treat AI-assisted development as a force multiplier, not a shortcut. I still design the architecture, define the data model, and own every technical decision; I just execute faster."

My work spans backend systems built from first principles (a hand-rolled flat-file persistence layer in TixCore), serverless edge deployment across Terminal CV and this portfolio, and agentic infrastructure automation. Formal training in MCP, the Claude API, and agent-skill design means I don't just use AI tools. I understand their architecture well enough to build with and around them. The result is a developer who ships production-shaped software at a pace traditional workflows can't match, without sacrificing the engineering fundamentals that make that software maintainable.

Certifications

Ongoing, self-directed upskilling across AI tooling, cloud infrastructure, and networking fundamentals.
