A software studio, run by brothers
We build software that ships. And holds up when it matters.
Joza is Zach and Josh Feldman. We're two brothers who've spent seven years, side by side, taking products from the first commit to real production. Software leaders, one team, no handoffs.
SERVICES
Three things we do well.
Small studio, senior hands. You work with the two people actually building it - start to finish, no account managers in between.
AI that holds up
Agents, retrieval, and LLM features built for real, messy, private data - and the scrutiny that comes with sending it to production.
- Agents & tools
- RAG & retrieval
- Runs on your data, in your environment
Design & build, 0 → 1
You bring the idea or a rough draft. We design it, build it, and ship it - the same team from sketch to production.
- Web & mobile apps
- MVPs you don't throw away
- Enterprise-grade infrastructure
Infrastructure & scale
The plumbing that keeps a product fast, cheap, and boring to run: cloud, CI/CD, and data pipelines. Invisible when it's working.
- Cloud & Kubernetes
- CI/CD & developer tooling
- High-throughput data pipelines
TRACK RECORD
What we've built.
Some of this we shipped as Joza. A lot of it we did over the years inside other companies.
Shipping AI into places that don't trust AI
We've built agentic systems that run against sensitive, proprietary data - and made it through the security and risk reviews that decide whether they ever go live.
- AI agents
- Private data
- Risk & compliance
Mobile EV Charging Platform
On-demand EV charging: roadside charging assistance for EV consumers + enterprise fleets. Two React Native apps and an admin portal - two-way messaging, geofencing, ETA tracking, delayed payment capture, and push notifications.
- React Native
- Expo
- Next.js
- GCP
A patent for keeping work reliable offline
We invented a system, now protected by a US patent, that keeps clinical-trial assessments reliably scheduled offline in low-bandwidth places where you can't count on a reliable network.
- US patent
- Systems design
- Healthcare
Data pipelines at scale
Event-driven pipelines moving 1+ TB a day, with real-time identity resolution and pluggable vendor integrations - the kind of plumbing you only notice when it breaks.
- Data
- Kafka
- Event-driven
Medical Billing OCR
Handwritten medical billing into clean, digitized PDFs using OCR and document parsing - a messy, real-world data problem made boring.
- OCR
- Document parsing
- Pipelines
THE STUDIO
Two brothers. One team.
We've worked side by side for seven years - through scrappy 0 → 1 launches, to systems inside companies where breaking things isn't an option. Hire Joza and you get both of us: the same two people who design it, build it, ship it, and pick up the phone when something's wrong.
- Say less.
- We finish each other's sentences. No translation loss between design and build, no meeting to plan the meeting.
- Ship the outcome.
- Not the ticket, not the demo - the result you actually hired us for. We do whatever the job needs to get there.
- Own the whole thing.
- The same two people design it, build it, and deploy it - and stay on the hook long after it's live.
