Jean-Michel Lalarme

Marketing that builds useful digital tools.

Strategy, content, AI and prototyping connected to turn concrete needs into usable websites, tools and MVPs.

Selected Work

Proofs of a profile that can both frame the need and build the solution.

Each card shows a concrete bridge: business context, product decision, and usable execution outcome.

Sport Track

A training product built for real mobile use, where sync reliability is a trust and retention issue.

React / TypeScript / PWA / Cloudflare Worker / D1

Problem

Athletes lose confidence when offline edits, delayed sync and conflicting updates make training history unclear.

Solution

Designed explicit product states for sync, conflict resolution and restore previews directly in the core journey.

Value

The tracker stays credible in daily usage and supports consistent training decisions instead of data anxiety.

Garde-manger

A collaborative pantry workflow that reduces friction in shared everyday decisions.

Vite / Cloudflare Workers / D1 / CI

Problem

Household collaboration breaks when stock updates collide and nobody knows which value is current.

Solution

Added concurrency checks, clearer feedback loops and safer release rules for a stable shared operational tool.

Value

Usage becomes smoother for non-technical users and easier to maintain without hidden coordination costs.

Lead Engine

A marketing-oriented prospecting engine that turns local data into qualified outreach actions.

FastAPI / Jinja2 / SQLite / SQLAlchemy / pytest

Problem

Sales outreach often starts with fragmented local data, weak qualification, and repetitive preparation work.

Solution

Structured a single workflow for import, scoring and message preparation, with guardrails on the critical execution paths.

Value

Qualification gets faster, prospecting decisions become clearer, and marketing actions are easier to repeat with quality.

24_enhance

A data-to-publishing workflow where release discipline matters as much as analysis quality.

Python / Make / pytest / GitHub Actions

Problem

Sports data publication loses trust when simulations and live sources drift without clear release ownership.

Solution

Built validation gates and explicit source-to-release controls to keep outputs auditable before publication.

Value

Releases become more predictable and easier to explain to stakeholders when decisions rely on the numbers.

Lady Pole Dance EVJF

A conversion mockup built from field observation, offer reframing and clear booking intent.

HTML / CSS / JavaScript

Problem

The offer had visibility but weak conversion structure: unclear promise, weak reassurance order, and diffuse next steps.

Solution

Rebuilt the landing hierarchy around audience intent, local business context and a tighter CTA sequence.

Value

The page better supports qualified inquiries and demonstrates concrete marketing-to-product execution.

What I build

I build the bridge from market understanding to usable product delivery.

The objective is practical: clarify the offer, structure the tool, and deliver something people can actually use.

Conversion websites

Service pages and landing flows that make the offer easier to understand and easier to act on.

Internal tools

Interfaces that remove repetitive work and expose states, permissions and errors clearly.

Automation systems

Pipelines that collect, transform and publish data with fewer manual gaps and better control.

Product MVPs

Early products built to validate real workflows without painting over technical risk.

Approach

Method over hype: structure first, AI as an execution lever.

I use AI to accelerate production, not to replace product thinking, user clarity, or operational discipline.

Clarity first

The interface should explain the product quickly before it asks for attention.

Explicit states

Sync, conflicts, retries and edge cases should be visible, not hidden behind generic success screens.

Operational discipline

Runbooks, smoke tests and publish checks matter when the product has to keep working after launch.

Useful simplicity

Less surface area, fewer moving parts, stronger decisions.
