DevOps Engineer

I build things people actually use — from browser to cloud.

I'm Madushan Samayasivam — a DevOps Engineer practitioner based in Sri Lanka. I started in the browser: Three.js environments, perceptual hashing engines, Canvas-based game systems. Now I'm pushing into the stack below the application layer — containerising services with Docker, wiring CI/CD pipelines, deploying to AWS.

My work sits at the intersection of engineering precision and visual storytelling. ImageSync was built to solve a real NGO field problem. Helapidi ships with zero install. ContainerDrop runs on EC2. I don't stop at "it works on my machine."

Case Studies.

01

ImageSync — Browser-Native Similarity Engine

Tool Design · JavaScript · Performance Engineering

Web App
+

ImageSync started from a real KFHI field problem: hundreds of child photos from KoBoToolbox surveys needed to be matched and renamed against reference images — manually, one by one. That was clearly broken. I decided to build a browser-native tool that could do it in bulk, instantly, with no server.

01

Problem Definition

Manual photo matching in NGO fieldwork. Time cost: hours per session. Error rate: high.

02

Research & Algorithm

Evaluated MD5, pHash, dHash, and DCT perceptual hashing. DCT won for robustness against compression artifacts.

03

Performance Engineering

Moved hashing to Web Worker thread to prevent UI blocking. Binary search compression for output sizing.

04

UI/UX Design

Obsidian Studio aesthetic — premium dark theme, drag-and-drop zones, confidence score visualization.

Result

Reduced photo-matching time from hours to minutes. Zero backend required. Used in live KFHI field operations. Full browser — works offline.

02

The Quiet Protocol — Psychological Horror Game

Game Design · Narrative UX · Web Audio · APOGEE GameJam 2026

Game · Jam Entry
+

Built for APOGEE GameJam 2026 (BITS Pilani × Postman). The constraint: make a horror game using only document-processing mechanics. No monsters, no jumpscares. Just decisions that compound into silence. The horror is the logic.

01

Concept & Constraints

48-hour jam. Theme: "The Operator." Built the concept around bureaucratic horror and the Milgram experiment.

02

Narrative Design

12 turns. Curator arc. Mirror Finale. Memory Quarantine mechanic. Every choice has a cascading consequence.

03

Technical Build

Single-file HTML. Web Audio API for ambient sound. Surveillance camera animations. Phase 3 visual distortion effects.

04

v2 Iteration

Added player name personalization, animated cameras, complete sound system rebuild, and enhanced Phase 3 effects post-jam.

Result

Completed psychological horror experience in a single HTML file. Demonstrates narrative design, audio engineering, and UX storytelling beyond typical game jam entries.

03

Hēlapidi — Browser Multiplayer Shooter

Game Development · Multiplayer Systems · Vanilla JavaScript

Game
+

The premise was simple: what if a Sri Lankan-inspired multiplayer shooter ran entirely in the browser — no Unity, no install, no account? Just open the tab and play with someone next to you. Proving that browser games can have real multiplayer depth.

01

Architecture Decision

Chose vanilla JavaScript over frameworks. Canvas API for rendering. Delta-time physics for frame-rate independence.

02

Multiplayer Design

Local multiplayer first — removes backend latency. Designed keyboard layouts for two players on one keyboard.

03

Cultural Identity

Hēlapidi references traditional Sri Lankan string games. Visual identity and character design reflect this heritage.

04

Modular Refactor

Refactored from monolithic script to 18 ES6 modules. Also ported core mechanics to Unity/C# with Netcode for GameObjects.

Result

Flagship studio project demonstrating multiplayer systems, game loop engineering, and cultural product positioning — all in a zero-install browser experience.

Let's build something worth remembering.

I'm currently open to DevOps engineering roles, cloud infrastructure internships, frontend engineering contracts, and remote work globally. If you have something interesting — a pipeline to build, a system to containerise, an interface to engineer — I want to hear about it.
