faster development cycles
Removed a JBoss bottleneck that was slowing down feature delivery for more than 15 engineers.
Freelance Java + Angular engineer
I help product teams build, untangle, and ship business-critical web platforms—owning the work from Java services to Angular interfaces.
Best fit: a product already carrying real users, real constraints, or both.
I have spent my career inside large, imperfect, high-stakes products. The goal is not prettier code. It is a team that can deliver with more confidence.
Removed a JBoss bottleneck that was slowing down feature delivery for more than 15 engineers.
Helped evolve registration and transaction services handling more than 50,000 e-signatures every day.
Built and supported a real-time billing platform while owning production incidents and a major B2B migration.
Bring me in where ownership is unclear, delivery is slowing down, or a valuable feature needs to cross technical boundaries.
I take ownership across the stack—from domain decisions and Java APIs to the Angular experience—so your roadmap does not stall between teams.
I find the constraint that is costing your team time, then simplify the code, architecture, or delivery path around the outcome that matters.
I work comfortably in business-critical systems where uptime, migrations, integrations, and clear incident ownership are part of the job.
Small independent builds are where I test product judgment, infrastructure choices, and end-to-end ownership without a handoff.
On-chain analytics
A tool for calculating profit and losses of on-chain transactions, providing accurate financial insights of blockchain transactions.
Backend automation
The bot uses grid trading to profit from price variations. Running on a VPS with real money, security is a top priority.
Live web product
A fitness tool to calculate your one-rep max and plan your training progression.
No theatre and no black box. We agree on the outcome, surface the risks early, and keep working software in view.
We clarify the user outcome, the technical reality, and what success needs to look like before adding code.
You see useful software early. Decisions stay close to evidence instead of disappearing into a long implementation phase.
The result is maintainable by the people who own it next, with the important trade-offs made explicit.

The person behind the work
I am Tanguy, a French product engineer based in Bangkok. I work best with teams that value direct communication, pragmatic decisions, and real ownership.
My background spans transport, e-signature, telecom, and data platforms. That experience taught me how to enter complex systems without treating complexity as inevitable.
Tell me what is stuck, what needs to ship, and what a useful outcome would look like. I will reply with a direct next step.
