What We Build

One Team. Every Layer of Your Stack.

Strategy, design, engineering and operations under a single roof — so nothing gets lost between handoffs.

Custom Software Development

Bespoke platforms, ERPs, internal tools and SaaS products architected around how your business actually works — not the other way round.

Node.js.NETPythonGoMicroservices

Web Application Engineering

Blazing-fast, SEO-ready web apps and portals built on modern frameworks, with performance budgets and accessibility baked in from day one.

ReactNext.jsVueTypeScriptHeadless CMS

Mobile App Development

Native and cross-platform iOS & Android apps with offline-first architecture, polished motion and analytics wired in before launch.

FlutterReact NativeSwiftKotlin

Cloud & DevOps

Infrastructure-as-code, CI/CD pipelines, containerisation and 24/7 observability — so releases become routine instead of risky.

AI, Data & Automation

LLM assistants, predictive models, document intelligence and workflow automation that remove the busywork and surface the decisions.

How We Work

A Process Built for Momentum

Short loops, visible progress, zero mystery. You always know what shipped this week and what ships next.

01

Discover

We map goals, users, constraints and success metrics, then turn them into a scoped, costed roadmap.

02

Design

Architecture diagrams and clickable prototypes so you can feel the product before a line of code exists.

03

Build

Two-week sprints, demo every Friday, code reviewed and tested continuously in your own repository.

04

Scale

Launch, monitor, optimise. We stay on as your engineering partner with SLA-backed support.

Why Sintellex

Senior Talent.
Zero Drama.

We keep teams small, senior and accountable — the quickest path from idea to something real in production.

Senior-only engineering pods

Every project is staffed with experienced engineers and a dedicated tech lead. No juniors learning on your budget.

You own everything

Source code, infrastructure, documentation and IP are yours from the first commit. Full transparency, no lock-in.

Time-zone friendly delivery

Overlapping hours with US and EU teams, daily written updates, and a channel where someone always answers.

Built to scale, priced to start

Fixed-scope MVPs or long-term dedicated teams — start small, expand only when the numbers justify it.
