the development process

A holistic approach I've shaped through my own experience and keep evolving with every new project and the AI tools and trends I follow, focused on building products that meet real user needs and grow the business.

What principles drive my developer journey?

The mindset

product & growth

I build products that answer a real user need. Every build ties to an OKR and a metric that should move: activation, conversion or retention.

user & business advocate

I start from real user needs, gathered in interviews and read in analytics and funnels, and build for them while aligning the work with business OKRs.

data driven

I prioritize data-driven decisions and advocate for improvements or deprecations with solid rationale.

agent orchestration

I direct AI agents across the stack, exploring AI-driven solutions with critical thinking and my own taste.

shipping velocity

A clean dev → preview → production flow, built to ship fast, measure and iterate.

honest communication

Clear communication: sharing progress, discussing blockers and aligning priorities.

cross collaboration

My work is enriched by close collaboration with UX designers, CX, engineers, CTOs and CEOs.

How do I actually build?

My build loop

1

define

Understand the problem, the user's needs and why it matters

Align on OKRs and scope with stakeholders and clients, when needed

Start planning with agents, letting them map the codebase, docs and more

DEFINE

2

orchestrate

Implement across the defined stack with Claude Code

Create agents, commands, hooks and skills

Connect the MCPs that wire the tools together

BUILD

3

review

Decide across trade-offs, keeping architecture decisions & taste mine

Define tests, docs and refactors

Understand the AI's work and run agents to review before production

JUDGE

4

ship

Test locally, then on dev and preview

Ship to production with a clean flow

Use agentic browser extensions for the quick final review

SHIP

5

measure

Instrument with analytics (PostHog funnels, session replay)

Read activation, conversion & retention

Turn the data into the next growth iteration

GROW

How do I work with AI?

The setup I direct

I use agentic tools to work better and faster, always as tools I direct: I organize the information they need and connect it to the right ones, while I define the architecture and the trade-offs. That lets me ship more and reach professional results across areas beyond my original expertise, like design, UX writing and data analytics.

Claude Code

My environment of choice right now, though I can pivot to another quickly if a project calls for it. I keep a structure of synced markdown files that feed the agent its context and keep the work moving fast.

MCP servers

For every tool in my stack I check whether it has an MCP, so I can drive it from my terminal and stay in one flow. Today that includes PostHog, Figma, Vercel and Notion.

commands, hooks & skills

Custom Claude Code tooling I build for myself: commands for repeatable flows I trigger on demand, hooks that run automatic checks and guardrails on each action, and skills related to my know-how.

subagents & workflows

For bigger jobs I split the work across subagents, each on a scoped task running in parallel, and bring the results back together. I make the architecture decisions and the final call.

Which tools do I use?

Tools I've worked with so far. I'm always adding more as a problem needs it, picking them up fast with docs and AI.

Frontend

HTML, CSS, JavaScript, TypeScript, React.js, Next.js, TailwindCSS, many more...

Backend

Node.js, Nest.js, Python, Docker, Stripe, Solidity, and others...

Database

PostgreSQL, MongoDB, Redis, Firestore, Supabase, Neo4j

Data

PostHog, BigQuery, Google Cloud Platform, Jest, Cypress

Collaboration

Figma, Notion, Slack, Jira, always open to add new ones
