Product development
Full-cycle frontend development from requirements to production. Architecture, implementation, code review, and delivery. No half-measures.
8 years building frontend systems that survive the real world — fintech, SaaS, and real estate. Business first. Clean code follows.
Whether you have a half-built product, a new idea, or a team that needs a senior hand — here's what I bring to the table.
Full-cycle frontend development from requirements to production. Architecture, implementation, code review, and delivery. No half-measures.
Component libraries and design systems that scale. One codebase, consistent UI, fast delivery on every new product your team builds.
When the team is stuck or the pipeline doesn't exist — I build the process, onboard the developers, and establish a delivery rhythm.
Architecture review, tech stack decisions, performance audits. I help you make the right call before it becomes an expensive mistake.
Real problems. Real constraints. Real results.
Fintech · Team leadership · Pipeline
Joined a product 4 months behind schedule. Two developers, no process, no delivery. Built a team of 8, established the full dev pipeline, and shipped the first iteration in 30 days.
SaaS · Design system · Scale
Three separate products, one fragmented codebase, inconsistent UI everywhere. Built a shared component library from scratch — 20+ components, aligned with the design system.
Real estate · Architecture · Ambiguity
No clear requirements, tight deadline, requirements changing weekly. Took the product from raw ideas to first delivery — on time, without drama.
No surprises, no guesswork. Here's what working together looks like.
We talk through your product, your team, and your constraints. I ask the questions that matter. You get a clear read on whether I'm the right fit. No sales pitch, no commitment.
Before writing a single line of code I map out the problem, the risks, and the approach. This is where most projects fail — rushing into implementation. I don't do that.
Weekly updates, clear milestones, no black boxes. You always know where we are, what's next, and what decisions need to be made.
Production-ready code, documentation, and a clean handoff to your team. Not "it works on my machine" — it works everywhere, on schedule.
Sound like how you want to work?
Let's start with a 30-minute call — no commitment, no pitch.

Brander
Web studio — e-commerce platforms, mobile apps, multiple client projects. First professional work: learning to ship on deadline, every time.
Senior Software Engineer focused on frontend architecture and delivery. Eight years building products people actually use — fintech, SaaS, real estate.
The best technical decisions start with understanding the business. Deadlines, constraints, and goals come first. Clean code follows, not leads.
I don't pick technologies by popularity. I pick them by requirements, team experience, and what actually solves the problem. Modern doesn't always mean better. Familiar doesn't always mean right.
I never start building without analysis. Not the code, not the architecture, not the team setup. Rushing into implementation is how projects fail — and I've seen it too many times to repeat the mistake.
