Alex I

software engineer & founder, alion tech studio

Alex I is an independent software engineer and the founder of alion tech studio, with over a decade of hands-on experience building production systems across the full stack. He has designed and shipped native mobile applications for iOS and Android, built backend APIs handling millions of requests, architected multi-region cloud deployments on AWS and GCP, and hardened web applications against the kinds of vulnerabilities that appear in real incident reports. The studio's writing comes directly from that work — from diagnosing actual performance regressions, from configuring Content Security Policies that block real attack vectors, from the trade-off decisions that do not appear in documentation.

background and experience

Over his career Alex has worked across early-stage startups and established product teams, in roles spanning individual contributor engineering, technical lead, and independent consulting. He has built and maintained systems in TypeScript, Swift, Kotlin, Go, and Python; deployed infrastructure using Terraform and Pulumi; and operated services on Kubernetes with zero-trust network policies. He holds a strong working knowledge of the OWASP Top 10 and has performed security reviews and hardening for production web and mobile applications.

His focus areas in depth:

  • Mobile apps — native iOS (Swift, UIKit, SwiftUI) and Android (Kotlin, Jetpack Compose), and cross-platform development with Flutter and React Native. Experience with secure offline storage, cryptographic authentication flows, and app-store deployment pipelines.
  • Backend systems — RESTful and GraphQL API design, PostgreSQL and Redis data modelling, event-driven architectures with message queues, and reliable server-side engineering in Node.js and Go.
  • Frontend development — performance-first web interfaces in React and Next.js, modern CSS layout and animation, Core Web Vitals optimisation, and WCAG-compliant accessibility engineering.
  • Cloud architecture — scalable infrastructure on AWS (Lambda, ECS, CloudFront, RDS) and GCP (Cloud Run, Firebase, BigQuery), infrastructure as code with Terraform, CI/CD pipeline design, and serverless edge computing.
  • Application security — zero-trust network architecture, hardened HTTP response headers (CSP, HSTS, permissions policy), OAuth 2.0 and OIDC implementation, OWASP-aligned threat modelling, and automated vulnerability scanning in CI.

writing

The insights section publishes in-depth, field-tested articles on web performance, security, accessibility, and cloud architecture. Every piece is drawn from real engineering work — not rewrites of documentation or SEO filler. The goal is to explain the mechanism clearly enough that you can reason about edge cases, not just follow a checklist. Articles cover topics like TypeScript compiler internals, HTTP caching semantics, WebAssembly performance characteristics, zero-trust security design, and CSS layout engineering — each written with enough depth to be useful to a working engineer, not just an interested reader.

consulting

Alex takes on a limited amount of consulting work in the same areas covered by the writing: web performance engineering, application security, mobile and fullstack development, and cloud infrastructure. Engagements typically involve performance audits, security reviews, architecture design, or hands-on development. Availability is limited — but if you have a project where deep technical expertise in these areas would make a difference, reach out at support@aliontechstudio.com.
