Seif Ashraf · Lyrnic

Senior Software Engineer · Founder-CTO · Backend, AI Systems, Android & SaaS Architecture

I build production-grade systems with a focus on clean architecture, reliability, security, and ruthless edge-case handling.


Backend AI Systems Android SaaS Architecture Security

Building Kalemly

Founder-CTO at Kalemly

Building a social-commerce automation platform for local brands, focused on AI-powered customer conversations, order handling, payment validation, and human handoff workflows.

Kalemly is where I combine backend architecture, AI agents, SaaS operations, payment workflows, and production reliability into one product.

AI Commerce Automation SaaS

What I Build

Backend & SaaS Platforms

APIs, authentication, caching, dashboards, multi-tenancy, audit logs, and infrastructure for systems that need to survive real production usage.

AI Systems

Agent workflows, provider orchestration, RAG-style systems, voice pipelines, realtime events, and production-safe automation layers.

Android Products

Native Android apps using Kotlin, Java, Jetpack Compose, clean architecture, Room, Hilt, coroutines, and lifecycle-safe design.

Security & Integrity

Custom integrity validation, certificate-chain verification, device trust signals, abuse-resistant APIs, and backend-backed protection.

Selected Work

Area Work
Android Product Built Viking Player, an Android media app with 100K+ downloads and strong user ratings.
Integrity Systems Designed backend-backed validation systems as an alternative to relying fully on third-party attestation APIs.
AI Infrastructure Worked on low-latency voice/conversation systems with VAD, STT/TTS orchestration, realtime events, and provider fallback strategies.
SaaS Platforms Architected multi-tenant SaaS workflows including authentication, audit logs, automation, dashboards, and business operations tooling.

Tech Stack

Engineering Principles

Clear architecture      > clever code
Reliability             > hype
Explicit contracts      > hidden behavior
Maintainability         > shortcuts
Security by design      > security as an afterthought
Production correctness  > demo-only happiness

Good architecture should make systems easier to change, not harder to understand.

Currently interested in production-grade AI agents, multi-tenant SaaS, realtime voice systems, Android architecture, security, caching, and infrastructure automation.
