Everything from
MVP to enterprise scale

Security-first engineering across the full stack — built to scale, built to last, and built to withstand real-world threats.

01/06

Secure SDLC

Security woven into every stage — from requirements through deployment, with automated SAST/DAST scanning at every commit.

02/06

Full-Stack Web Apps

Modern, responsive web apps built with React, Next.js, Node.js, Python, or your preferred stack — security at the foundation.

03/06

Enterprise SaaS

Multi-tenant, cloud-native SaaS platforms for high availability, compliance, and rapid iteration without compromising security.

04/06

API & Microservices

RESTful and GraphQL APIs, event-driven microservices, and service mesh architecture — built for scale and auditability.

05/06

Code Review & Audit

In-depth security-focused code reviews identifying vulnerabilities, anti-patterns, and technical debt before they become breaches.

06/06

DevSecOps & CI/CD

Automated security testing in CI/CD — SAST, DAST, dependency scanning, and container security baked into every pipeline.

How we build
secure software

01

Discovery

We map your requirements, threat model, and compliance needs before a single line of code is written.

02

Secure Design

Architecture and API contracts designed with zero-trust and least-privilege principles from day one.

03

Build & Test

Agile sprints with continuous security testing — SAST, peer review, and pen test checkpoints every release.

04

Deploy & Monitor

Hardened cloud deployment with real-time monitoring, alerting, and ongoing vulnerability management.

Common Questions

Everything you need to know about working with SpyPro on a custom software engagement.

How do you ensure security throughout development?
We follow a Secure SDLC — threat modelling at design, mandatory SAST at every commit, DAST on staging, and a full penetration test before any production release. Security is never a phase; it's a continuous practice throughout the engagement.
What is the typical project timeline?
MVPs typically take 6–10 weeks from scoping to first production release. Enterprise platforms range from 3–9 months depending on complexity. We work in 2-week agile sprints, so you see working software and security reports at every milestone.
Do you work with our existing codebase?
Yes — we regularly onboard onto existing codebases. We start with a code audit to understand architecture, identify debt, and agree a roadmap before adding any features or fixes. We never rip-and-replace without clear justification and your sign-off.
Who owns the code at the end?
You do — 100%. All IP, source code, and documentation produced during the engagement is assigned to you at project close. We sign an IP assignment agreement before work begins so there's no ambiguity.
Can you support and maintain the software after launch?
Yes — we offer retainer-based maintenance packages covering bug fixes, dependency patching, security updates, and feature iteration. Many clients stay on a monthly retainer with a dedicated engineer familiar with their codebase.
