Fullstack Engineer

Puntadewa Zaid B.

Fullstack Engineer Designing Fast, Scalable Systems from Idea to Production.

I build products with an architecture-first mindset, balancing elegant UX, resilient backend design, and measurable business outcomes.

Performance-first engineering. System design mindset. Product-focused execution.

About

Engineering With Intent

I am a builder at heart. I enjoy turning ambiguous problems into reliable systems, from frontend interaction details to backend throughput and observability. My focus is not just shipping features, but making engineering decisions that stay fast, maintainable, and scalable as products grow.

Main Section

What I Build

Selected systems and products designed with performance, reliability, and measurable impact in mind.

Realtime Commerce Analytics Platform

Built a real-time dashboard for monitoring conversion funnels and campaign attribution across multiple storefronts.

  • Next.js
  • Node.js
  • PostgreSQL
  • Redis
  • WebSocket

Reduced reporting delay from 30 minutes to under 10 seconds.

Fleet Ops Scheduling Engine

Designed an optimization service that auto-generates dispatch schedules with route and SLA constraints.

  • TypeScript
  • NestJS
  • GraphQL
  • Docker
  • AWS

Increased on-time deliveries by 22% while reducing manual planning effort.

Developer Platform for Internal Tools

Created a modular internal portal with RBAC, audit logging, and reusable UI primitives for engineering teams.

  • Next.js
  • tRPC
  • Prisma
  • Tailwind CSS

Cut time to launch new internal tools from weeks to days.

Physics-Driven Indie Game Prototype

Experimented with gameplay loops, deterministic simulation, and scene optimization for browser delivery.

  • Three.js
  • React Three Fiber
  • WebGL
  • Blender

Sustained 60 FPS on mid-range devices with low-poly assets.

Mindset

How I Think

My approach to building software that remains dependable under growth and complexity.

Start from constraints: user experience, latency budget, and operational complexity.

Model the system before writing code, then optimize interfaces between components.

Prioritize observability and testability so scaling is predictable, not accidental.

Treat performance as a product feature, measured continuously in production.

Growth

What I’m Exploring

I invest in emerging ideas that can unlock better products and engineering workflows.

  • Distributed systems patterns for event-driven architectures
  • WebGPU and rendering pipelines for browser-based interactive apps
  • Practical AI integration in developer workflows
  • Game-feel design and real-time simulation techniques
