Building Real Software, from Pixels to Production
Simha StudioA digital invitation SaaS for weddings and bar mitzvahs, designed and built solo and running in production: quotes, guests, RSVPs and seating in one portal.
Grades multiple-choice exams from scans or phone photos. OpenCV realigns the page (ORB + RANSAC), reads every bubble and sends ambiguous marks to a human before any score is final.
A design system and complete app redesign for Roomatch AI, an agent that hunts apartments for you: describe the home once, it searches, scores every listing and opens a chat when the landlord says yes.
Next.js apps with auth, roles, a real database and transactional email.
REST design, validation, authentication, ownership rules and rate limiting.
Image registration, thresholds and diagnostics with OpenCV and NumPy.
Type checks, unit tests and browser tests that block every merge.
LLM agents and workflows wired to real tools, data and email.
App redesigns and design systems, from the first flow to every state of every screen.
Tokens, components and documentation that stay in sync with the product.
Branding, typography and layout. My first craft, before code.
How I work
Decisions come first. Before the code, I write down the architecture, the data model and the why. Simha Studio and PsychoMark both keep a decision log and a living roadmap.
Then I build in small, verified steps: typed code, tests next to the feature, and CI that blocks on lint, types and tests.
Finally, I ship. Real users, a real domain, real feedback, and a commit history that explains every change.
By the numbers
Approach
I like software that is easy to trust: clear boundaries between modules, data that never lies about its state, and an interface that tells people exactly what happens next.
In PsychoMark, the optical engine never sees the answer key, and no grade is final while a mark is ambiguous. In Simha Studio, one source of truth drives every order status, from the dashboard to the Excel export.
Background
I started as a self-taught graphic designer: brand identities, logos and UI concepts on the Adobe suite and Figma.
Design taught me to care about the details people feel. Code let me build the whole thing.
Today I study software engineering (Handasai Tochna) and ship products end to end.
Beyond the code
Simha Studio started as a single bar mitzvah invitation, coded by hand. Then came a wedding RSVP form. A few months later it had a client portal, an admin dashboard, WhatsApp delivery and a seating planner.
Looking for
An internship where I can ship real features with a team, in full-stack web, backend or computer vision. French, Hebrew and English.
