Launch fintech products in weeks, not months.
We help startups and B2B SaaS fix architecture, scale systems, and ship production-ready software fast.
We design scalable, production-grade and cost-efficient systems on Google Cloud Platform (GCP) and AWS.
Cloud & Infrastructure
We design cloud architectures that handle real-world load — launch spikes, payment traffic, and scaling bottlenecks.
Built primarily on Google Cloud Platform, with AWS used when required.
- Cloud architecture & migration
- Kubernetes & containerized workloads
- High-load infrastructure (launch spikes, traffic bursts)
- Cost optimization & performance tuning
GCP / AWS Stack
Enterprise-grade infrastructure
Trusted by fast-growing fintechs and enterprises
Who we work with
We bring the most value to dynamic tech companies that need to move fast without breaking things.
B2B SaaS startups
Fintech companies
High-growth tech products
Core Services
We specialize in solving complex engineering challenges for fast-moving companies.
Revenue-generating products launched in weeks
From zero to MVP and beyond. We take full ownership of your product development, allowing you to focus on business growth and user acquisition.
Stabilizing crashing architectures to handle massive scale
Inherited a failing codebase? System crashing under load? We audit, stabilize, and rebuild architectures to handle massive scale safely.
Fintech architecture that survives scale & PSP limits
Designing resilient, microservices-based or modular monolithic architectures specifically tailored for transactional business and FinTech.
LLM features that drive real product value (not demos)
Implementing LLMs and machine learning pipelines into your B2B SaaS to create unfair advantages against your competitors.
Scaling Ticketing Platform to €500k+/month
How we designed a distributed architecture to support high-load ticket sales spikes without breaking a sweat.
Context & Stack
Client:High-growth ticketing platform
Stack:GCP / Kubernetes / PostgreSQL / MongoDB / Kafka
The Problem
System failing at peak events, frequent timeouts during sudden ticket drops, and slow transaction processing causing customer churn and lost revenue.
The Solution
Re-architected the core pipeline using a distributed architecture, leveraging Kubernetes for auto-scaling and Kafka for robust asynchronous processing.
Results Delivered
- Designed distributed architecture
- Supported high-load ticket sales spikes
- Reduced infrastructure costs by 30%
- Implemented real-time analytics
Deep Specialization.
Zero Distractions.
We don't chase every new framework. We are elite specialists in the Python ecosystem. For FinTech, Data-heavy B2B SaaS, and AI platforms, Python is the undisputed king. We leverage it to build secure, robust backends at unprecedented speeds.
- High-performance APIs (FastAPI, Django)
- Secure transactional architectures for FinTech
- AI-driven code generation for rapid MVP delivery
- Scalable infrastructure & Data Engineering
