Esteban Z.
Developer
We don’t sell templates or prebuilt products. Every company works differently — so we design and build systems around how your business actually runs, then stay to support and improve them over time. Led by Esteban (Senior Solutions Architect, ex-Tier 4 Twilio) with 8+ years working on APIs, SaaS platforms, and production systems — the kind of environments where things break and need real solutions. Alongside: • Maria — operations, customer support, organization • Emanuel — engineering, development, system stability We work as one unit, not separate freelancers. 🧠 How we approach your business We don’t start with code — we start with understanding how things actually work. We meet with you and your team, observe real workflows, and identify: • where time is being lost • where systems don’t connect • where work is repetitive Then we design something that fits your reality — not a generic workflow. Most companies run on 3–5 disconnected tools. We bring that into one system that actually makes sense for your team. 🧱 What we build • Internal platforms (web + mobile) • Contact centers (Twilio / custom / AWS) • Automation systems + AI integrations • CRM & operations tools • Long-term support and continuous improvements Everything is modular — built to grow with you. 🚀 Example — Our First Client in the Solar Industry: We built and maintain their internal operating system. Before: • Multiple tools • Disconnected workflows • Manual processes Now: • One unified system (web + mobile) • Ops, comms, scheduling, HR, finance in one place • Automation handling repetitive work We meet twice per week, improving continuously. New needs → added as modules (no rebuilding, no chaos). Result: • Less tool switching • Lower software costs • Better team coordination 💼 How we work Understand your current setup Analyze workflows as a team Design a system around your operation Build, deploy, and keep improving We stay involved — this isn’t “deliver and disappear.” 🤝 What we’re looking for We’re not chasing volume. We’re looking for 1–2 companies that want to: • build something solid • improve operations over time • work with a team long-term
