01Make the right thing buildable
Product architecture
I translate business rules and user journeys into a product system: roles, states, boundaries, data contracts, and a delivery sequence that reduces risk.

Senior product engineer · Flutter + Node.js
Your mobile product, rescued or launched.
I help founders and product teams turn stalled apps and ambitious MVPs into stable products. I own the application, backend, and operational web experience as one system.

Senior product engineering
One product.
Four connected layers.
I work across the decisions, interfaces, systems, and operational tools that determine whether a product merely launches or keeps working as it grows.
02Make complexity feel calm
Flutter applications
Production mobile experiences with resilient navigation, state management, payments, realtime behavior, offline awareness, and the edge cases users eventually find.
iOS + AndroidRealtime UXRelease readiness
03Give the product a solid core
Backend systems
Node.js APIs, authentication, data models, notifications, queues, integrations, observability, and cloud foundations designed around how the product actually behaves.

04Build for the team behind the app
Web operations
Admin dashboards and operational tools for support, dispatch, risk, reporting, content, and daily decisions. This web layer makes a mobile product operable.

Focused ways to work together
Choose the product risk.
I’ll own the outcome.
I take on a small number of products so founders get senior judgment, direct communication, and one engineer accountable across application, backend, and web.

Read case studyA low-drama delivery process
Clear from first call
to final release.
You always know what is being built, what changed, and what comes next. The process is deliberately simple.
Fit call
We clarify the product, current blockers, commercial goal, and whether I am the right fit.
Scope
You receive a practical delivery plan with milestones, assumptions, timeline, and a clear first sprint.
Build
I work in small releases with weekly demos, concise updates, and visible decisions. You always see what is happening.
Ship
We test the important paths, release with confidence, and agree on support or the next product milestone.
Client perspective
Trusted with products that people actually use.
“He understood the pace of the product and moved just as fast. A great engineer to work with.”
Vlad MacoveiCEO, Agrointelligenta.ro“The app made it easy for our members to stay connected and streamlined everything on our end.”
Matt KingstonCEO, GymChamp Mobile AppsBefore we speak
Useful answers,
up front.
What projects are the best fit?+
Flutter products that need a backend, admin dashboard, rescue work, or a senior owner who can move between product decisions and implementation.
Can you work with my existing team?+
Yes. I can own a defined feature or release, work alongside your designer and backend team, or take responsibility for the full app-to-API workflow.
How quickly can we start?+
Small audits can usually begin within a week. Larger builds start after scope, access, and milestones are agreed. Current availability is confirmed on the fit call.
Do you only work through Upwork?+
No. We can work directly or through Upwork, depending on your procurement preference. The delivery process and communication standard stay the same.
Free product strategy call
Bring the product.
Leave with clarity.
Tell me where the product is today and what needs to happen next. I’ll ask the useful questions and give you an honest view of fit, risk, and the first sensible step.
