01 Core services

Engineering built around the system you actually run.

Built for businesses that need strong software systems, reliable integration, and long-term technical ownership.

01

API Engineering

Robust REST and event-driven APIs with auth, rate limits, observability, and clear contract design.

Scalable service interfacesWhy it matters Best when your product, partners, or internal tools need a dependable contract for exchanging data.
02

ERP and CRM Systems

Custom internal systems for operations, sales, fulfillment, and customer lifecycle workflows.

Business process alignmentWhy it matters Best when sales, fulfillment, and service teams are stitching work together across disconnected tools.
03

SQL and NoSQL Databases

Schema design, indexing strategy, migrations, data governance, and performance tuning.

Reliable data architectureWhy it matters Best when slow systems, unreliable reports, or difficult changes are tracing back to the data layer.
04

Web Crawlers and Data Collection

Crawling pipelines with scheduling, extraction, normalization, and anti-fragile retry behavior.

Production crawling frameworkWhy it matters Best when your team needs repeatable external data, not another fragile one-off script.
05

Mobile App Development

Cross-platform mobile products with secure APIs, offline support, and polished UX.

iOS and Android deliveryWhy it matters Best when a customer or field workflow needs to work securely away from a desk.
06

Online Marketplace Development

Two-sided platforms for listings, search, transaction flows, and trust workflows.

Marketplace operations built-inWhy it matters Best when you need to make buyers, sellers, listings, and operational controls work as one system.
07

Data Sync and Automation

Bi-directional sync, idempotent workers, queue orchestration, and business workflow automation.

No more manual transfer loopsWhy it matters Best when your team is re-keying data, chasing status, or reconciling multiple sources of truth.
08

Software Design and Architecture

System architecture, domain modeling, API contracts, and maintainable technical boundaries.

Long-term maintainabilityWhy it matters Best before a major build or modernization, when the right decisions will save costly rework later.
09

Product Engineering

End-to-end engineering across frontend UX, backend reliability, security hardening, and DB stewardship.

Complete software ownershipWhy it matters Best when you need one accountable partner across the user experience, backend, security, and data.
02 Engagement models

Choose the engagement that matches your stage.

Each model is a different amount of engineering ownership, not a different standard of work.

03 Delivery model

A disciplined path from architecture through launch.

Every engagement runs the same five stages. Nothing moves forward until the previous stage has a decision behind it.

Discovery and requirement architecture

We map the workflow, the systems it touches, and the constraints that decide what can ship.

System design and implementation plan

Data model, service boundaries, and a sequenced plan with explicit acceptance criteria.

Feature build with quality gates

Incremental delivery behind tests, review, and a running risk register.

Security, performance, and release hardening

Access control, load behavior, and failure paths verified before anything reaches users.

Launch, support, and iterative improvement

Instrumented release, operational runbooks, and a steady cadence of improvement.

04 Transparent pricing

Published starting points, not discovery-call pricing.

Final scope is set after discovery. These are the real entry points for each engagement type.

Architecture Sprint$5,000fixed scope

System audit, architecture map, and prioritized implementation plan.

Engineering Partner$6,000per month

Ongoing delivery, maintenance, and roadmap ownership.

05 How we build trust

You should never have to ask where the project stands.

Visible progress

Weekly delivery updates tied to acceptance criteria

Named risk

Scope and risk register maintained from day one

Transferable work

Implementation docs included for internal handoff

06 Industries we serve

Where software decides whether the business runs well.

We work best with teams where software directly affects revenue, operations, and customer experience.

07 Ecosystem next steps

Ironclad handles the software core.

When the platform is solid, these specialized segments take the next constraint.

Model Foundry

For AI-heavy features layered on top of core software platforms

Visit Model Foundry Where it fits Explore this when the next step is an AI capability built on top of a solid software foundation.

Harborlight Marketing

For funnel and conversion execution after platform launch

Visit Harborlight Marketing Where it fits Explore this when the platform is ready and the next constraint is qualified traffic, conversion, or retention.
08 Frequently asked

Questions teams ask before they start.

Can you work with our existing codebase?

Yes. We audit what exists, preserve what is solid, and modernize unsafe or high-friction areas incrementally.

Do you handle both product and internal systems?

Yes. We build customer-facing products and internal ERP or CRM systems that share reliable data foundations.

How do you reduce delivery risk?

We use staged scopes, clear acceptance criteria, and production-grade testing and observability before release.
