Full-stack web development, API integration, cloud deployment, custom security tooling, and data visualisation — shipped with DevSecOps built in from day one.
Our Software Services division builds production-grade web applications, APIs, cloud infrastructure, and custom tooling. Every delivery is backed by our DevSecOps approach — security, testing, and CI/CD are not afterthoughts; they ship with the product.
Full-stack builds using FastAPI, React, and Node.js — from landing pages to complex multi-user platforms.

Quatech builds full-stack web applications for businesses that need reliability, security, and maintainability — not just a working prototype. We use FastAPI and Node.js/Express on the backend, React for interactive frontends, and SQLite or PostgreSQL for data persistence.
Our DevSecOps approach means every application ships with JWT authentication, input validation, rate limiting, CSRF protection, parameterised queries, and security headers configured by default. This is not a checklist we run at the end — it is the way we write code.
Projects are versioned on GitHub, tested with automated test suites (pytest / Node:test), and deployed to cloud infrastructure with a CI pipeline from day one.
FastAPI (Python) and Node.js/Express backends
React single-page applications and server-rendered frontends
JWT authentication with access and refresh token flows
8 DevSecOps security controls built into every application
Automated test suites with minimum 80% coverage
GitHub-versioned delivery with CI/CD pipeline
We document user stories, functional requirements, data flows, and security requirements before writing a line of code. Scope is agreed and signed off.
System architecture, database schema, API contracts, and UI wireframes are designed and reviewed. Technology stack is confirmed for the project context.
Code is written to our internal DevSecOps standard: parameterised queries, validated inputs, encrypted secrets, security headers, and rate limiting applied throughout.
Automated tests cover health endpoints, authentication flows, authorisation (RBAC), input validation, security headers, and business logic — minimum 20 tests per project.
Applications are deployed to agreed infrastructure (Render, AWS EC2, or client environment) with environment variable management, logging, and uptime monitoring configured.
Full codebase, README, API documentation, and deployment runbook are handed over. A 30-day post-launch support window is included.

Clean, documented RESTful APIs and robust cloud infrastructure — designed to scale and built to stay online.
Quatech designs and builds RESTful APIs that are clean, versioned, documented, and secure. We integrate third-party services including payment gateways, identity providers, mapping APIs, and data enrichment services — handling authentication, error handling, and rate limiting correctly from the start.
On the infrastructure side, we deploy to AWS EC2, Render, and DigitalOcean using reverse proxies (Nginx), process managers (PM2/Gunicorn), SSL termination, and environment variable management. We set up monitoring and alerting so your team knows before users do when something goes wrong.
Whether you need a single microservice or a multi-service cloud architecture, we scope it to your current needs without over-engineering for hypothetical futures.
RESTful API design with OpenAPI / Swagger documentation
Third-party API integration (payments, auth, data services)
AWS EC2 and cloud deployment with Nginx reverse proxy
SSL/TLS certificate management and HTTPS configuration
Environment variable and secrets management
Uptime monitoring and deployment runbook documentation
We define endpoints, request/response schemas, authentication method, versioning strategy, and error response format before any code is written.
Endpoints are built with full input validation (Pydantic / express-validator), authentication (JWT), rate limiting, and consistent error handling throughout.
External APIs are integrated with appropriate retry logic, error handling, and timeout management. Webhook handlers are built and tested against live sandbox environments.
Cloud instances are provisioned, hardened (SSH keys, firewall rules, fail2ban), and configured with the application stack, reverse proxy, and process manager.
SSL certificates (Let's Encrypt or provided) are installed and auto-renewed. DNS records are configured and HTTPS enforced across all endpoints.
Uptime monitoring, log shipping, and alerting are configured. Full deployment runbook and API documentation are included in the handover package.

Purpose-built security tooling for your specific threat environment — scanners, monitors, automation, and detection engines built to your requirements.
Off-the-shelf security tools solve general problems. Quatech builds custom tools for your specific operational context — whether that's a scanner tuned to your application stack, a monitoring script for your specific log format, or a detection engine for a threat pattern unique to your environment.
Our CyberLab portfolio of 23 published security tools demonstrates our capability: HTTP security header scanners, keylogger detection systems, subdomain enumerators, SOC alert triage simulators, network traffic analysers, and cryptographic tools — all built with Python/FastAPI or Node.js/Express, tested with automated suites, and deployed on production infrastructure.
Every tool we build is documented, versioned on GitHub, and tested before delivery.
Web application security scanners (headers, SSL, exposure)
Network reconnaissance and enumeration tools
Log analysis and threat detection automation
Monitoring agents and alerting pipelines
Custom reporting and compliance dashboards
CLI and web-based interfaces, as required
We document what the tool needs to detect, scan, or automate; what inputs it takes; what outputs it produces; and what environment it runs in.
Tool architecture is designed: CLI vs. web interface, API integrations, data storage, output formats, and scheduling or trigger mechanism.
Code written in Python or Node.js following our DevSecOps standard. No hardcoded credentials, no command injection vectors, input sanitisation throughout.
Automated tests validate core functionality, edge cases, error handling, and security controls. Tools are tested against representative environments before delivery.
Tools are deployed to your environment or packaged for self-hosting. Integration with existing workflows (SIEM, ticketing, alerting) is configured.
Full technical documentation, usage guide, and operator training are included. Source code is handed over on GitHub.

Interactive dashboards and data pipelines that turn your operational data into clear, actionable insight.
Quatech builds data visualisation tools and reporting dashboards that give your team instant clarity on what matters: security metrics, operational KPIs, financial data, network performance, or whatever is critical to your business.
We work with React-based interactive frontends, Python data pipelines (pandas, folium, matplotlib), and RESTful data APIs to build dashboards that are fast, accurate, and easy to use. Our mapping and geolocation work includes IP visualisation and threat geography as part of our Netra platform development.
Legacy reporting processes that run on spreadsheets, manual exports, or slow queries are common targets for modernisation — we've rebuilt several into real-time web dashboards with significant efficiency gains.
Interactive web dashboards (React, Chart.js, D3)
Python data pipelines (pandas, SQLite, PostgreSQL)
Geolocation and mapping visualisation (Folium, Leaflet)
Real-time data with WebSocket or SSE streaming
Automated report generation (PDF, CSV, email delivery)
Legacy reporting modernisation — spreadsheets to live dashboards
We identify your data sources, key metrics, reporting cadence, and the decisions the dashboard needs to support. Existing reports are reviewed as a baseline.
Wireframes are produced for each view, agreed with stakeholders before development begins. Chart types, filters, and drill-down interactions are defined.
ETL or ELT pipelines are built to extract, transform, and load data from your sources into the dashboard's data layer. Scheduling and incremental refresh are configured.
Interactive dashboard is built in React with responsive design, role-based access control, and export functionality (CSV, PDF) as required.
Data accuracy is validated against source systems. Performance is tested under representative load. UI is reviewed for usability with end users.
Dashboard is deployed and user training delivered. Data pipeline monitoring is configured with alerting for pipeline failures or data quality issues.
