Hands-On CTO | Product Engineer who believes technical leaders should still ship code.

I'm a technical leader with 10+ years building products from 0→1 startups to scale. I write code, lead teams, and drive product strategy—because the best engineering leaders do all three.

What I do: Bridge product vision with technical execution. Review PRs. Refactor legacy code. Mentor through pair programming. Ship features that move business metrics.

Impact: VP of Eng at Auriga (↓30% bugs, ↓60% security vulnerabilities, monthly→weekly releases) | CTO at Givfolio (built full platform from scratch) | Backend Engineer at Rakuten (8M monthly users, 30% faster responses)

I don't believe in "non-coding CTOs." Here's how I stay technical while leading:

• Code Reviews: I review architecture-critical PRs and mentor through detailed feedback
• Pair Programming: Regular sessions with engineers to solve complex problems together
• Refactoring: I fix tech debt myself, not just ticket it
• Prototyping: When evaluating new tech, I build it first
• Production Debugging: I jump into incidents and fix what's broken

I build products, not just features. This means:

const myApproach = {
  before_code: [
    "What problem are we solving?",
    "What's the business impact?",
    "What's the simplest solution?"
  ],

  while_coding: [
    "TDD/BDD for quality",
    "Clean Architecture for maintainability",
    "Performance monitoring from day 1"
  ],

  after_shipping: [
    "Monitor real user behavior",
    "Measure business metrics",
    "Iterate based on data"
  ]
};

Results over activity: I measure success by outcomes (user satisfaction, bug reduction, delivery speed), not lines of code or features shipped.

Sustainable engineering: Green software practices, efficient architectures, and code that's built to last—not rewrite in 6 months.

ERP platform serving major educational institutions across France

Hands-on transformation of delivery and engineering culture:

• ↓30% bugs, ↓60% security vulnerabilities through code quality practices I implemented and contributed to
• Monthly→weekly releases by fixing CI/CD pipelines and establishing trunk-based development
• Led Spring Boot 2→3 and Angular 12→18 migrations (wrote migration scripts, reviewed every PR)
• Bootstrapped testing culture: 0%→12% backend coverage, 58%→62% frontend
• Led team of 15 while maintaining active code contributions

Tech: Spring Boot, JOOQ, Angular, PostgreSQL, GitLab CI

Social impact mobile platform - San Francisco

Built the entire product from idea to production:

• Sole engineer for MVP, then scaled to small team
• Architected serverless-first platform on AWS (Lambda, DynamoDB, API Gateway)
• Owned product discovery through design thinking workshops with users
• Implemented Stripe payments, social features, real-time updates
• Infrastructure as code with Terraform from day 1

Tech: React Native, Node.js, AWS Lambda, DynamoDB, Terraform, Stripe

Major e-commerce platform - 8M monthly users

Performance engineering at scale:

• Migrated search to ElasticSearch: 30% faster response times
• Refactored batch processes: 4x performance improvement
• Built real-time product indexing pipeline replacing legacy batch system
• On-call rotation handling production incidents for millions of users

Tech: Spring, ElasticSearch, Couchbase, Oracle, Akka, Spark

I share lessons learned from building products and leading teams:

Dev.to - Deep dives on engineering leadership, architecture patterns, and delivery practices

Topics: Product engineering, software craftsmanship (TDD/DDD/Clean Architecture), technical leadership

Open to: CTO/VP of Engineering roles/Product Engineer at product-focused companies that value hands-on technical leadership

Interested in: Early-stage startups (0→1) or scale-ups optimizing delivery (10→100).

What I bring: Technical vision + execution. I can architect your platform, hire your team, and still review PRs.

Best for:

• CTO/VP roles where I can write code AND set technical direction
• Advisory/consulting on delivery transformation or engineering culture
• Speaking opportunities on product engineering or technical leadership
