WHY LONG-TERM WORKS BETTER
Handing a codebase to a new contractor every quarter is how products rot. Context gets lost, architecture drifts, and each new person rebuilds instead of extends.
When I stay, decisions compound. I know why the schema looks like that, which shortcut we took under deadline, and what breaks if you change it.
DESIGN AND ENGINEERING, ONE PERSON
Most teams hire a designer, then a developer, then spend three weeks translating between them. I do both, which removes that gap.
I run discovery, map user flows, design in Figma, build the design system, then implement it myself in React and Next.js. Nothing is lost in handoff because there is no handoff. Nothing gets designed that can't be built.
For founders without a design team, you get from idea to a real product without hiring twice. For teams that already have designers, you get someone who implements their work to spec instead of approximating it.
I design for outcomes, not for dribbble onboarding flows that finish, pricing pages that convert, dashboards people can read under pressure.
WHERE I USUALLY COME IN
→ An idea and no designs yet — discovery through wireframes and UI into a working product.
→ An MVP from scratch — scoped and scalable rather than overbuilt.
→ Scaling a product with traction — it works, but architecture is now the constraint.
→ Rescuing an unstable platform — the previous team left and it breaks in production.
→ A redesign or modernization — it works, but looks a decade old and converts like it.
→ Adding AI — RAG, agents, workflows, ai automations or LLM features integrated without destabilizing what works.
Past Experiences:
One of the largest Web3 node infrastructure providers in the world developer-facing product surfaces used daily by thousands of engineers building on-chain.
A venture-backed cloud deployment platform product interface, Frontend App and marketing site, Docs and Guides etc designed and built end to end.
A real estate analytics platform for multifamily operators data-heavy dashboards where the hard problem was hierarchy, not decoration.
An enterprise smart-stadium platform large-scale venue operations frontend under real reliability constraints.
WHAT I DESIGN AND ARCHITECT
Product discovery, user flows, wireframes through high-fidelity UI. Design systems that stay consistent past the first release instead of fragmenting into forty button variants. Multi-tenant SaaS with real tenant isolation. Data models that survive scale. RAG pipelines that return grounded answers instead of confident nonsense. Cloud infrastructure sized to your stage and budget. Observability before the incident, not after it.
HOW I WORK
I'm Founder and CTO of StellarStack, so I've lived with my own architecture decisions for years, not weeks.
I start with the business goal, not the ticket what you're measuring, your real constraints, and what this system looks like in eighteen months. That produces a plan with scope, milestones and rollout, instead of a stream of commits.
I build it so your team could own it: typed end to end, documented, no dependency on me. Then I usually stay anyway, because most clients would rather keep shipping than manage a handover. If you need more capacity than one person, my team at StellarStack scales up around the work.
I'll also tell you when the thing you asked for isn't the thing you need. If a two-week feature won't move your metric, I'd rather say so in week one.

GOOD FIT IF
You have real users or real funding and want someone who owns outcomes, not tickets. I work solo, embed with your team, or lead the developers on it accountable either way for how it looks, how it works, and whether it holds up in production.
PROBABLY NOT A FIT IF
You need WordPress edits, or you're shopping for the lowest rate on the platform, or the scope is "an app like Uber" on a $2k budget.
NEXT STEP
Tell me what you're building and where it's stuck, and let's get a call booked to talk it through single project or ongoing partnership, same invitation. First conversation is on me, and you'll get a straight answer on whether I'm the right person before you spend anything.
