Custom software for organizations that can't afford to drift.
Keelport Systems designs and operates the web platforms businesses run on, built with senior engineers end to end, made accessible by default, and structured to keep running long after launch.
The work, plainly.
No retainer theatre, no per-seat lock-in. Senior engineers shipping the things businesses actually run on.
Multi-tenant web platforms
Production SaaS with role-based access, isolated tenant data, real-time dashboards, and the operational hooks you need from day one.
Dashboards & internal tools
Operational consoles, reporting layers, and the internal apps your team needs to actually run the business, not just see it.
Payments & e-commerce
Stripe-powered checkout, billing, subscriptions, and reconciliation, wired into the rest of your product so finance stops chasing spreadsheets.
Integrations & APIs
REST, webhooks, and queue-based pipelines that connect the systems already in your stack, CRMs, identity, billing, analytics, the rest.
Product rebuilds & rescues
Taking over a stalled codebase, replacing a fragile MVP, or modernizing the platform a previous team left behind. Honest scope, no rewrites for ego.
Operate & evolve
After launch we stay on as the senior team behind the product, monitoring, security patching, iterating, and shipping the next quarter's roadmap.
A modern stack, run with discipline.
We pick proven tools and apply them carefully. No framework cosplay, no half-finished migrations, just a stack your future team can actually maintain.
What every engagement gets, in writing.
A short list of things we put in the statement of work, not aspirations, defaults.
Fixed scope, written estimate
A signed statement of work with deliverables, timeline, and price before any code is written. No surprise change orders.
You own the code & the accounts
Source code, repositories, cloud accounts, and domains are yours from day one. We work in your accounts, not ours.
Senior engineers, named
The engineers on your project are named in the SOW. The person you scope with is the person who writes the code.
NDA & reference-checkable
We sign mutual NDAs as a default and can arrange reference calls with prior clients during procurement.
Insured & incorporated
Canadian-incorporated, commercial general liability and professional liability coverage on file; certificates available on request.
Documented handoff
Every project ends with runbooks, architecture notes, and an onboarding doc your next engineer can read on day one.
How we work.
Senior engineers, small team, full ownership of the outcome.
Frame
One short engagement to map the actual problem, the constraints, and what success looks like in measurable terms.
Design
Architecture, data model, access boundaries, and the interface, designed together so they don't fight each other later.
Build
Senior engineers writing the code. Automated tests, peer review, CI, and a staging environment from day one.
Operate
Monitored, patched, evolved. You own what we build, we stay on to keep it running well.
From a first real product to a platform overhaul.
We work with teams that need senior engineering judgment, not a body shop. Three shapes of engagement show up most often.
Growing SMBs
Owner-operators and small teams ready to graduate from spreadsheets, off-the-shelf tools, or a fragile first build into a real product.
Regulated & professional services
Law, accounting, healthcare, and financial firms where auditability, access control, and uptime aren't negotiable.
Nonprofit & public sector
Mission-driven organizations modernizing the systems that serve people.
15+ years of experience. 20+ projects in the last three.
Our team brings more than fifteen years of experience across web platforms, data systems, and operational software, and in the last three years alone we've shipped over twenty production projects under the Keelport Systems banner.
A senior team, across a broad range of builds.
Our recent work spans multi-tenant SaaS platforms, customer portals, operational dashboards and internal tools, Stripe-powered billing and e-commerce, API and integration layers, accessibility-driven public-facing sites, and rescue engagements taking over stalled or fragile codebases. The common thread: senior engineers owning the work end to end, and a product that keeps running after we hand over the keys.
Engagements typically run from six-week scoped builds to multi-year operating partnerships.
What we deliver to a senior standard
- Tenant isolation & role-based access control
- Automated test & CI pipelines on every change
- Observability, alerting, and incident playbooks
- Stripe billing, subscriptions, and reconciliation
- WCAG 2.1 AA accessibility from the first commit
- Documentation a future team can actually read
15+ years of experience
Across the team, more than fifteen years of professional engineering experience, covering production web platforms, data architecture, payments, and the operational side of running software once it's live.
20+ projects shipped in the last 3 years
From first version products to platform overhauls, internal tools, integration work, and ongoing operating engagements, shipped quietly under NDA in most cases, which is why this page describes the shape of the work rather than naming clients.
Straight about scope
Where a project is the wrong fit for senior in-house work, a marketing site, a one-off integration, a no-code build, we'll tell you and point you somewhere better. It costs us a project; it earns the next one.
Start a project.
Tell us what you're trying to build or fix. We'll respond within two business days with whether we're the right fit and what a sensible first step looks like.
We take on a small number of engagements at a time: commercial product work, fractional senior engineering for in-house teams, and select public-sector RFPs.
Tell us about the project.
A few quick fields. We read every message ourselves and reply within two business days.
