About me

Adithya Dilum.

A curious mind. A backend focus.

I turn complex problems into dependable APIs, thoughtful data models, and full-stack products. I care about clear code and seeing things through, from the first idea to production.

Education: University of MoratuwaThird-year IT undergraduate
CGPA: 3.79

Beyond the codeA little creativity, in 3D.

06 / The path so far

Different problems.
A clearer direction.

Each project changed what I paid attention to. Five milestones, from a first working app to the systems behind a product.

Get in touch

01
2023–2024Foundations
The first working system.
A C# desktop application brought records, appointments, billing, and relational data into one working flow.
- C# / .NET
- SQL Server
Hospital Management System
02
2024–2025Hardware & real time
Code met the physical world.
Sensors, timing constraints, and failsafes changed how I thought about correctness and control.
- ESP32
- C++
- FreeRTOS
ESP32 Flight Controller
03
2025–2026Team & delivery
The work grew beyond my editor.
Leading an asset-management project meant owning requirements, team decisions, data integrity, and delivery.
- Next.js
- PostgreSQL
- Keycloak
TIQRI Assets
04
2026Backend platforms
The boundaries became the design.
Multi-tenancy, durable webhooks, and server-side authorization became the foundations of a service-business platform.
- ASP.NET Core
- PostgreSQL
- Docker
DayBoard
05
NowCurrent directionIn progress
Fewer shortcuts. More depth.
Going deeper into databases, concurrency, Linux, and reliable delivery—and documenting what the work teaches me.
