About

Archivios Engineering is written by Sambit Sarkar, founder of Archivios and a software architect with nearly two decades of experience building mobile and enterprise systems. Archivios is a cold-storage photo backup app.

I write about the engineering decisions behind the product, and more broadly about mobile architecture and how I am adopting AI responsibly in software engineering. It's where we document the reasoning, not just the outcome.

This is a technical publication focused on architecture decisions, engineering trade-offs, communication, career lessons, and notes from continued learning.

Focus Areas

• AI-First Development & Modernization
• Mobile Platforms (iOS, Android, Cross-platform)
• Software Architecture & System Design
• Legacy Modernization
• Engineering Leadership

The primary content here is Architecture Decision Records (ADRs) — structured documents that capture the context, decision, and consequences of significant technical choices.

We also publish shorter posts on specific technical topics.
