Full-stack web & app development
Modern web applications and customer portals, from dashboards to scheduling tools, designed to feel fast on desktop and mobile.
Software, Security & Intelligence
We build software that grows your business and protects it from day one.
Web platforms, APIs and AI tools for startups and engineering teams, with security in the foundation instead of added the week before launch.
00 / Approach
Teams are usually told to pick one: ship quickly or ship securely. We build so you don't have to choose.
- For founders
- A production-ready platform on schedule, without inheriting technical or security debt.
- For tech leads
- Extra engineering capacity: clean code, documented APIs and CI/CD pipelines your team can own.
- Principle
- Validate before you build. We check what is actually running against what the documentation says, then design.
- Principle
- Honest by default. Clear scope, plain-English reporting and no security claims we can't back up.
01 / Services
What we build.
Four disciplines, one team that understands how they fail together.
API engineering & digital workflows
Backend services and integrations that connect your tools, automate manual work and keep data moving reliably under load.
Application security & DevSecOps
Code and architecture review, database-level access controls and automated checks inside your delivery pipeline.
See security workAI engineering & intelligent tools
Search and automation that respect user permissions: retrieval-augmented generation, agent tooling and human approval for high-impact actions.
02 / Selected work
Systems we've built.
Clean interfaces, dependable backend APIs and hardened security layers.
Full-stack SaaS
Fitness & Gym Management
A turn-key platform for gyms, studios and personal trainers: workout logging, membership scheduling, client activity tracking and responsive frontend state handling.
AI tool gateway
FlowPilot
A gateway that stops AI models from making unintended database writes or taking unreviewed actions. Requests wait in a server-side approval queue until a human confirms them.
Data integration
Relay Event Engine
A resilient webhook service that normalizes incoming data, processes each event once, verifies HMAC signatures and routes failures to a dead-letter queue with automatic backoff.
Multi-tenant RAG
Atlas AI Search
An enterprise assistant that answers from private documents. Vector queries are joined to organization scope inside PostgreSQL, so tenant isolation is enforced by the database, not only by application code.
03 / Security work
Detect. Harden. Document.
Security practice backed by working code and written-down decisions, not slideware.
Detection engineering & monitoring
Building and tuning detections, triaging alerts and monitoring environments so real incidents surface and noise doesn't.
Application security
Authentication and token handling, Row-Level Security, rate limiting and logging, reviewed against the OWASP Top 10.
Cloud security
IAM review, least-privilege design and CloudTrail-based detection on AWS.
Governance, risk & compliance
Risk registers, ISO 27001-aligned control mapping, data-protection records and breach-response planning.
Selected security projects
PORTFOLIONode.js · TypeScript
Vulnerability Triage Platform
A triage tool that scores findings with a CVSS v3.1 calculator and enforces a severity threshold in CI.
- CVSS v3.1 calculator
- Authenticated Express API
- CLI gate for CI pipelines
- 30 unit tests and a GitHub Actions pipeline
- Multi-stage Dockerfile
Reference architecture
Secure Multi-Tenant BaaS & Lending
A secure-by-design blueprint for a lending platform on a multi-tenant backend.
View repository- STRIDE threat model
- LLM data-boundary design
- PCI DSS, GLBA and AML governance overlay
- CI check that fails builds on over-privileged database roles
04 / Process
How we work.
Clear scope, steady communication, security reviewed at every stage.
Discover & validate
A short call to understand goals, users, data sensitivity and timeline. We verify the real environment against its documentation before designing anything, then send a written scope and estimate.
Design & threat-model
We map the architecture and the likely attack paths together, so the risky decisions are made early, when they're cheap.
Build & verify
Iterative delivery with automated tests and security gates in CI, plus regular demos you can click through.
Launch & hand over
Production rollout, monitoring basics and plain-English documentation so your team can own and extend the system.
05 / Under the hood
Software and security, working together.
Pick a scenario to see the kind of validated execution behind a user action. Output is illustrative, not a live system.
06 / FAQ
Questions.
What kinds of projects do you take on?
New SaaS platforms and customer portals, API and integration work, security reviews and hardening of existing apps, and AI features such as RAG search or agent tooling. If you're unsure which bucket yours falls into, book a consult and we'll sort it out.
Do you only audit, or do you build too?
Both. You can hire us to build a product with security included, or to review and harden something that already exists, including adding automated security checks to your CI/CD pipeline.
How do you keep customer data separated in multi-tenant apps?
We enforce isolation in the database with PostgreSQL Row-Level Security, so a bug in application code can't quietly expose another tenant's rows. Then we test the boundary on purpose.
Can AI features be added safely to an existing product?
Yes. We scope what the model can read and do, tie retrieval to the signed-in user's permissions, and route high-impact actions through a human approval step before anything is written or sent.
Do you offer ongoing security monitoring?
Detection engineering and monitoring can be scoped as an ongoing engagement. We agree log sources, alert thresholds and response expectations up front so there are no surprises.
How do pricing and timelines work?
After a short discovery call you receive a written scope with a fixed estimate or a clearly defined retainer, depending on the work. Timelines depend on scope, and we'll say so plainly if a deadline isn't realistic.
