JUPI PLUS

JUPI PLUS is a custom software development shop based in Warsaw, Poland. The company builds web and mobile applications, SaaS platforms, and digital products for clients across eCommerce, FoodTech, EdTech, HR Tech, and logistics. They operate a managed project model where clients can choose from fixed-price engagements, dedicated teams, staff augmentation, or a fully managed development team approach.

The firm handles the full development lifecycle: from IT consulting and product discovery through architecture design, development, testing, maintenance, and 24/7 support. Public case studies show concrete outcomes—Outbidda, an online auction platform for collectors, launched across 200+ countries with integration of Stripe, ShipStation, Zendesk, and custom payment systems built over 24 months. Air Platter, a restaurant SaaS, grew its client base 5x and achieved 10+ business improvements. It Is Easy!, a moving and logistics platform, reduced costs by 20% and processed leads 3x faster. For a workflow automation client (NDA), they delivered a 5x productivity boost and eliminated 5+ paid services through consolidation.

They work with Node.js and NestJS on the backend, React and Vue.js on the frontend, and PostgreSQL, MongoDB as databases. They integrate third-party APIs (Stripe, Square, DoorDash, Uber Eats, Google Maps, Slack) and deploy to cloud platforms including Google Cloud, Vercel, and Render. Their team includes developers, designers, and strategists, though specific headcount isn't disclosed on the website. Recent job postings for Middle Python engineers, PHP engineers, and AI engineers (voice agents) suggest active hiring.

Initial response time is under 1 hour and proposals arrive within 24 hours. They offer a free 30-minute consultation call. The firm publishes regular technical content on their blog covering architecture decisions, scope management, EdTech, FoodTech trends, and SaaS product strategy, suggesting active thought leadership.

Services and capabilities

JUPI PLUS segments its offerings into discovery, architecture, development, testing, and support. On the discovery side, they offer IT consulting for startups and SMEs, market research, competitive analysis, feasibility studies, and PoC development. They also conduct technical audits and business analysis.

For architecture and planning, they scope MVPs, design cloud-ready systems with API strategy, plan feature prioritization, and align UI/UX to architecture. Full-stack development covers web and mobile apps, cloud deployment, database design, data engineering, and third-party integrations including payment gateways. They handle Stripe, Square, DoorDash, and Uber Eats integrations based on the case studies shown.

QA services include manual and automated testing, continuous integration and test-driven development, performance and load testing, security audits, and user acceptance testing. Post-launch, they offer SLA-driven maintenance, 24/7 monitoring, regular updates and release management, legacy system modernization, and technical debt reduction.

Notable work

Outbidda is a next-generation marketplace combining traditional auctions with raffles and exclusive drops. JUPI PLUS built a custom multi-layer financial system to handle both individual sellers and business accounts with secure payment processing, invoice automation, and tax calculations. They integrated a unified shipping module supporting multiple carriers for international deliveries. The platform launched across 200+ countries with Stripe, ShipStation, Zendesk, Mailgun, and Google Analytics integration. The founder, Gautam Sharma, noted they were "exceptional in brainstorming and sparring with me on ideas, going beyond just executing what was on paper."

Air Platter is a B2B SaaS for independent restaurants to manage online orders and reduce third-party commission dependency. JUPI PLUS built a custom onboarding experience instead of relying on third-party APIs, integrated Stripe and Square for payments, connected DoorDash and Uber Eats for delivery, and added marketing automation via Mailgun. The client achieved 5x client growth and introduced 4+ SaaS subscription tiers. Development took 12 months with a 6-person team.

It Is Easy! streamlines quote requests and lead capture for moving, logistics, and home services. JUPI PLUS reduced cost by 20%, accelerated lead processing 3x, and generated 1000+ new leads. The platform integrates Google Maps, SendGrid, Node.js/Express backend, and Vue.js/Sass frontend.

Two additional case studies are under NDA: one workflow automation platform for a content/localization business (delivered 5x productivity boost, eliminated 5 paid services), and one recruitment web portal (125% efficiency gain, 10+ hires post-launch, used Azure AD, Microsoft SSO, OpenAI, and Vue.js). An educational web portal for a U.S. organization improved data accuracy 5x and boosted user engagement 65%.
