Custom Software Development in New Jersey
Jiss Tech designs, builds, and modernizes custom software for New Jersey businesses: web and mobile applications, CRMs and business systems, API integrations, and workflow automation. Not slideware — systems that are running businesses in production today.
What we build
Software built around how your business actually works.
Every engagement starts from the work your team already does — then we design the system that removes the friction, instead of forcing your operation into someone else's product.
Custom web applications
Operations dashboards, customer portals, internal tools, and full products — built around your real workflow instead of a generic template.
Web app developmentMobile app development
iOS and Android apps designed, built, and shipped to the App Store and Google Play, like our own Kalamna voice platform and TimeStop game.
Mobile app developmentCustom CRMs & business systems
Customer records, scheduling, invoicing, messaging, and reporting in one system — like the eight-module auto-shop platform running in production today.
Custom CRM developmentAPI integrations & automation
Connect the tools you already use — payments, SMS, email, accounting, vendor APIs — and automate the handoffs your team does by hand.
API integration & automationModernization & software rescue
Take over aging or broken systems, fix what's failing, and modernize without stopping the business that depends on them.
Software modernizationSecurity assessments
Website security reviews, vulnerability assessments, and remediation planning for small businesses in NJ and NY.
Cybersecurity analysisProof, not promises
Systems already running in production.
Most agencies show mockups. These are real systems Jiss Tech engineered, shipped, and operates — the same engineering that goes into client work.
JNC Suite — automotive CRM
An eight-module operating system for an auto shop: customers, vehicles, estimates, invoices, SMS, appointments, and analytics. The shop reported customer retention up 89% after implementation.
FlightDetector — real-time tracking
A production flight-tracking system that reconciles six data sources with verification, caching, fallback providers, and database-enforced API budgets.
Kalamna & TimeStop — shipped apps
A real-time group voice platform on the App Store and a mobile game with global leaderboards — designed, engineered, and launched by Jiss Tech.
Principal-led, by design
No sales engineer. No account-manager handoff.
At most development companies, the person who wins your business disappears the day the contract is signed. At Jiss Tech, the person who scopes your system is the person responsible for building it — through architecture, implementation, launch, and support.
That means straight answers about what is worth building, what is not, and what it will cost — from the engineer doing the work, not a salesperson working a quota.
Local to New Jersey, not offshore
Jiss Tech works from Bayonne, New Jersey — in person across Hudson County, Jersey City, Newark, and the New York City metro, and remotely across the United States. Same time zone, same working hours, and a real office at 34 E 14th St, Bayonne, NJ 07002.
Dependable technology
TypeScript, React, Node.js, Python, PostgreSQL, AWS, Stripe, Redis, and Docker — chosen so your system stays maintainable for years, not rewritten every eighteen months.
How an engagement starts
Start small, with a fixed price and a real deliverable.
You don't have to commit to a large build to work with us. Each starting point is fixed-price, produces something useful on its own, and credits toward implementation if you continue.

A focused review of one website and its inquiry path, with three improvements ranked by impact.
Details48-Hour Workflow Map
One manual or spreadsheet-heavy process turned into an improvement plan and a fixed implementation quote.
DetailsLead Rescue Sprint
Immediate acknowledgment, routing, and response tracking around one existing lead source, live in five business days.
DetailsAuto-Shop CRM Pilot
An existing, working shop-management platform adapted to one independent repair shop.
DetailsFrequently asked questions
Custom software in New Jersey, answered plainly.
How much does custom software development cost in New Jersey?
It depends on scope, so we quote fixed prices instead of open-ended hourly billing. Small, well-defined projects start with published fixed-price offers — a $49 website diagnostic, a $250 workflow map, a $1,250 lead-response sprint, and a $2,500 auto-shop CRM pilot. Larger custom builds get a written fixed scope and price after a short paid scoping step, so you know the number before committing.
How long does a custom software project take?
Focused automation and integration work often ships in days to weeks — our Lead Rescue Sprint targets go-live in five business days. Full custom applications typically take one to several months depending on scope. We prefer starting with a small, useful first milestone in production rather than a long project with nothing live.
Do you only work with businesses in New Jersey?
No. Jiss Tech is based in Bayonne, New Jersey, and works in person across Hudson County, the wider New Jersey area, and the New York City metro — and remotely with businesses anywhere in the United States.
Who owns the software you build for us?
When we build custom software for you, the delivered system is yours — code, data, and accounts. When an engagement adapts an existing Jiss Tech product, such as the auto-shop CRM pilot, the written agreement spells out licensing up front so there are no surprises.
Can you take over, fix, or modernize software someone else built?
Yes. A significant share of our work is rescuing and modernizing existing systems: broken order-intake software, insecure sites, and businesses recovering from being hacked — including one client we rebuilt from scratch in under a week after a breach with no backups.
What technologies do you build with?
Mostly TypeScript, React, Node.js, Python, and PostgreSQL, deployed on AWS and modern cloud platforms, with Stripe, Redis, Docker, and the APIs your business already depends on. We pick boring, dependable technology that your system can live on for years.
