An independent software studio run by Della Reno Rinaldi. With 8+ years engineering production software, I work directly with founders and teams to ship fast, reliable digital products. Honest collaboration, zero junior handoffs.
Every application is architected directly by Reno — from reactive mobile state to fast edge API gateways.

React Native, Next.js, and modern cloud tech
Try real test builds on your own phone every week
A complete retail and cashier system built from the ground up: fast sales, real-time inventory, hardware receipt printing, and digital storefronts.
An end-to-end POS, inventory, and online store platform built for retail & F&B owners. Designed, engineered, and deployed live by renodotdev.
Native retail cashier companion designed for touch-first handheld and tablet operations with local SQLite storage for uninterrupted offline checkout.
Lightweight hardware communication protocol developed to stream raw byte receipt buffers across Bluetooth, USB, and LAN thermal receipt printers.
I keep client capacity intentionally small (1–2 projects at a time) so you get full focus, quick replies, and fast delivery. Tell me what you're thinking, and let's see how we can make it happen.
Whether you're starting from a napkin sketch or upgrading an existing product, here’s where we do our best work.
Cashier Terminal
Hardware BT • Thermal Print OK
Smooth, native feel with 60 FPS performance
Cross-platform apps built with React Native and Expo. Offline-friendly, hooked into hardware like receipt printers and scanners, and published straight to the App Store and Google Play.
Clean dashboards, fast websites, and solid backends
From custom backoffice portals to customer-facing web apps. Built with Next.js, Astro, TypeScript, and PostgreSQL for speed, good SEO, and zero headache maintenance.
Practical AI that solves real problems, not just hype
We add useful AI capabilities directly into your software — smart search, document parsing, automated workflows, and LLM integrations. Backed by solid code and automated tests, not fragile vibe coding.
You handle client relationships, brand identity, and UI design. renodotdev writes clean, documented, accessible code that integrates directly into your client's Git repositories. Fast turnaround, zero junior handoffs.
You get clear milestones, direct access to Reno on WhatsApp, and working progress to test on your own phone every week.
We sit down (virtually), outline exactly what needs to be built, and map out the technical plan so there are no surprises on scope or budget.
We build in fast, focused cycles. Every week, you receive a test build on TestFlight or staging web so you can see and feel real progress.
We push to production, help get your app approved on the stores, and hand over the complete code. You own 100% of everything we create.
Tactical architectural blueprints, performance deep dives, and real-world lessons from shipping high-scale software.
Hardening production backends against sophisticated automated scraping and credential stuffing: token binding with DPoP, mTLS service meshes, and Redis sliding windows.
The reality behind the micro-frontend hype: bundle size penalties, CSS pollution, shared dependency hell, and why high-performing teams are returning to modular monoliths.
Pushing the TypeScript compiler to its limits: conditional types, template literal pattern matching, recursive mapped types, and zero-runtime type guards.
8+ years engineering production mobile & web applications. You work 1-on-1 directly with Reno — no account managers, zero junior handoffs.
