Security-first engineering
We build security into delivery rather than bolting it on: least-privilege access, secrets kept safe, dependencies scanned, and review on every change. It runs through our AWS cloud architecture and DevOps work.
Least-privilege access by default
Most breaches come down to access that was broader than it needed to be. We configure IAM roles so each service and person has exactly the permissions required and no more, scope credentials tightly, and rotate them. Getting access right early is far cheaper than auditing it after something goes wrong, so we treat it as part of the build rather than a later clean-up.
- Tightly scoped IAM roles
- Short-lived, rotated credentials
- Access reviewed as part of delivery
Secrets out of the codebase, data encrypted
Secrets never live in the repository. We keep them in a managed secret store, injected at runtime, so a leaked codebase does not leak your keys. Data is encrypted in transit and at rest as standard. These are not optional extras; they are the baseline we build on, so security is not something you have to ask for separately.
- Managed secret storage, not in git
- Encryption in transit and at rest
- Secure defaults from the start
Dependencies scanned and kept current
Vulnerabilities arrive through the packages you depend on as often as through your own code. We scan dependencies for known issues, keep them current, and review what we add before it ships. Patching is part of ongoing maintenance rather than a fire drill, so known holes get closed before they become an incident.
- Automated dependency scanning
- Updates as routine maintenance
- New packages reviewed before use
Review on every change before deploy
Security is checked where the code actually changes. Every pull request is read by another engineer before it merges, and that review covers how data is handled and where access is granted, not just whether the feature works. Combined with a staging environment that mirrors production, it means risky changes are caught before they ever reach your users.
- A second engineer on every change
- Data handling reviewed, not just features
- Caught on staging, not in production
Secure across the whole stack
The same approach covers the AWS infrastructure, the Django and FastAPI backends, and how we ship through spec-driven, reviewed delivery.
Security questions
We follow AWS Well-Architected principles: least-privilege IAM, secrets kept out of the codebase in a managed store, encryption in transit and at rest, dependency scanning, and code review on every change. Security is built into delivery rather than treated as a separate add-on.
In a managed secret store, injected at runtime, never committed to the repository. Credentials are scoped tightly and rotated, so a leaked codebase does not expose your keys.
Yes. We can review an existing setup, tighten IAM and secrets handling, add dependency scanning, and close the gaps we find, as a focused engagement or ongoing.
