Cover image for Built a Collab Viewer style
Built a Collab Viewer style toolset inside the UE5.5 project and made it reliable for dedicated-server multiplayer. I migrated/merged the Collab architecture into a my project (GameMode, PlayerController, Pawns, PlayerState), fixed reference/compile issues, and wired the tools to our custom UI for both First Person and Orbit pawns. Key work included replication/RPC cleanup so tools work over a server, plus integrating tools like annotations (text, paint and erase), transform, Datasmith runtime loading (replicated so one client’s load appears for others), measuring/dimension tool (place/edit/delete and unit switching), and bookmarks (place, list UI and teleport with rotation). A network-ready collaboration layer in custom with UI-driven workflows and server-validated replication, ready for packaging/testing and ongoing polish

Cover image for Revolutionize Unreal Engine Workflow: Efficient Terrain Impo...
Terrain Importer for Unreal Engine (Python + Custom UE Plugin) I built an end-to-end terrain importer that converts raw terrain dataset files into fully usable Unreal Engine landscapes automatically. Before this, importing and setting up ~45 landscape tiles in Unreal could take ~60 minutes and was easy to mess up. I wanted a fast, repeatable pipeline. It allows: Python reads the dataset and generates Unreal-ready .r16 heightmaps Python automation creates a new Unreal project and imports the heightmaps Custom UE plugin (C++) builds Landscapes from the imported heightmaps and places them correctly in the level Foliage: automatically placed across the terrain The workflow reduce from ~60 minutes to ~5 minutes for ~45 landscapes (~12× faster) and made it deterministic and repeatable ideal when terrain needs frequent regeneration.

I recently worked on a multiplayer MMA-style project in Unreal Engine (C++), focusing on server-authoritative gameplay, replication/network flow, backend/API integration, and performance-minded polish. Loved the challenge of making combat feel fair and responsive under latency.

I worked on Sand Bullet (Unity 3D) a top-down shooter indie title and owned the full development cycle from early concept to final deployment. I built the core tech including enemy AI, a flexible weapon system, and in-game power-ups, then pushed it through release on Steam, where it picked up real user traction and feedback that helped shape polish and iteration.

Cover image for Today's win wasn't writing code.
Today's win wasn't writing code. It was fixing it. I spent hours tracking down an index.js issue that kept breaking my CLI. It wasn't fun but solving it taught me more than if everything had worked the first time. Errors don't make you a bad developer. Avoiding them doesn't make you a great one. Learning to debug does. Every bug fixed is another skill earned. What's one bug that taught you the most?

62% today. 100% is the goal. 🚀 I challenged myself to reach a 100% Discovery Score before the end of the month. That means showing up consistently, building in public, sharing what I learn, and creating value every day not chasing numbers. Every post is one step closer. What's one professional goal you're determined to achieve before this month ends?

Live at sagini.net (http://sagini.net). More at sagini.me (http://sagini.me). DM me and let's build something.

Cover image for Just shipped something I've
Just shipped something I've been building for a while. If you've ever started a Laravel project and spent the first two days just setting up JWT auth, user roles, protected routes and a basic API structure — this is for you. The Laravel JWT API Starter Kit gives you all of that out of the box. Register returns 201. Login returns 200 with a token. Every endpoint tested before release. It also includes posts CRUD with likes, comments, replies and view tracking. Zero config SQLite database. Clean structure that's easy to extend. Get it here: https://contra.com/iamsagini Pairs with Devboard, the Next.js dashboard I also just shipped. Buy both and have a complete full-stack application running in under an hour.
