Xavion Mirchandani

I build AI products and the systems around them.

I'm a student at Blair Academy who built Xavion AI, a multi-model AI platform. In the summer of 2026 I interned as a software engineer at Preface in Singapore, where I shipped production AI agents and built the company's internal CRM.

Where I’ve worked

Jun 2026 – Aug 2026
Singapore
Preface — Software Engineering Intern
Sole engineer on the Singapore team of Preface, a global technology-education company — built agentic automation and internal tooling that went into production for real client outreach.
- Built and ran a production multi-agent pipeline in Python that automates client outreach end-to-end: an outreach agent that drafts personalized emails with AI-researched company backgrounds, a scheduling agent that classifies reply threads and flags follow-ups, and a calendar-sync agent that reconciles Google Calendar with color-coded client statuses.
- Designed and shipped Preface 2559, the company's internal CRM platform — a Prospect → Won pipeline with a drag-and-drop board, per-business timelines, and a human confirm queue that gates every outward-facing agent action. Deployed at preface.sg.
- Hardened the platform for production: database migration baselines with CI, row-level security, a durable action executor with idempotency keys and full audit trails, and an agent evaluation suite of 40 fixtures including prompt-injection attacks.

Xavion AI — Founder & Developer
Founded and solo-built a multi-model AI platform that brings 30+ models from every major provider into one interface.
- Designed a unified abstraction layer over multiple AI provider APIs (OpenAI, Anthropic, Google, and others), normalizing authentication, request formats, and response structures.
- Implemented real-time streaming with Server-Sent Events and side-by-side conversations with up to six models at once, plus image generation and prompt refinement.
- Rebuilt the entire interface from scratch after the first version fragmented into separate pages — one product decision that shaped how I think about design.

Preface 2559

CRM platform · Preface internship

An AI-driven CRM platform built for Preface during my internship. Custom agents manage the entire client pipeline, classifying each business, updating its timeline, and proposing next actions as deals progress, while client-facing actions are gated behind human approval. The platform runs in production at the company.

Personal Investment Portfolio

Stock portfolio · Since 2022

A personal investment portfolio built and managed since the age of 10. The portfolio employs a Core and Satellite investment strategy, with the 'Core' consisting of high-conviction mega-cap tech stocks held on a 10-year horizon, and the 'Satellite' involving smaller tech positions allowing me to take profits, rebalance, and maximize returns based on market conditions. The portfolio has grown approximately 90%, shown on the below dashboard which fetches live market data to accurately track the portfolio's growth over the past few years.
