Alessandro Puddu Unity & Full-Stack Engineer

Unity / C# / TypeScript / Remote worldwide

Senior Unity & Full-Stack Engineer for Games, VR & Web

I join teams as an embedded senior engineer and deliver production systems end to end: Unity gameplay, VR and tooling on the client, and the TypeScript backends, APIs and web apps behind them.

5+ years of professional Unity/C# experience, including Alaloth, RaceClub for Sandbox VR, enterprise R&D at Capgemini Engineering and technical leadership at Squircle Games.

How I can help

Senior engineering without a narrow box

My core offer is long-term embedded engineering, in Unity or on the web stack. Project rescue and end-to-end delivery are focused ways to start when a team has an urgent problem or a clearly owned outcome.

01

Embedded senior engineering

I work inside your team, own complex systems, contribute to technical direction, and keep shipping alongside product, design, art and QA.

02

Unity project rescue

I map an inherited or unstable codebase, make risks visible, restore a reliable delivery baseline, and stay to carry the product forward when needed.

See the rescue approach
03

End-to-end delivery

I take responsibility for a feature or subsystem across runtime code, editor tooling, networking and supporting services—not just the first layer of the problem.

See delivery modes
04

Full-stack web & backend

TypeScript services and web apps, standalone or behind a game: Node and NestJS APIs, real-time WebSockets and socket.io, auth and sessions, PostgreSQL with Prisma, and React or Next.js frontends.

Where I work best

The hard parts between systems

A Unity product rarely fails because one API is missing. The difficult work sits between architecture, content, devices, user experience and production constraints.

View the full capability map

  1. 01

    Gameplay systems & NPC behavior

    Maintainable state logic, interaction systems, physics, simulation and debuggable game AI that designers and engineers can reason about.

  2. 02

    VR, WebGL & platform porting

    Input, spatial UI, platform services, persistence, memory and performance designed as deliberate boundaries instead of scattered conditionals.

  3. 03

    Performance & production diagnostics

    Profiling-led investigation across CPU, GPU, memory, assets and runtime behavior, backed by logs and tools that make regressions visible.

  4. 04

    Editor tooling & team workflows

    Purpose-built Unity tools that replace fragile manual work, encode validation rules and give non-programmers safe control.

  5. 05

    Networking & product integration

    Multiplayer, real-time transports, authentication, APIs, streamed media and supporting web services when the Unity runtime is only one part of the product.

  6. 06

    LLM, speech & interactive characters

    LLM integration, TTS/STT, streamed audio and character presentation, with explicit handling of async state, interruption and platform differences.

  7. 07

    AI-assisted engineering

    Extensive coding-agent use, supported by focused repository context, reviewable tasks, code review and automated validation. Senior ownership stays with me.

Selected evidence

Commercial work, clear contributions

Named engagements and public projects show where I have contributed. Descriptions stay at the level permitted by NDA: responsibilities and engineering scope, without private code or product details.

Sandbox VRUnity Developer · ContractMay 2026–present

RaceClub

Integrated UI Toolkit into runtime menus and HUD systems, connected interfaces to gameplay state, and delivered gameplay features, cross-device input and interaction feedback.

Enterprise R&DSimulation / immersive

Performance-critical real-time applications

A physics and simulation refactor took a key scene from 10 FPS to a stable 60. Also remote content, WebGL/VR delivery, multiplayer and in-app authoring.
