Calypso platform security, QA and consulting workflow

Calypso Services

Calypso Consulting, Security & QA Services

Experienced Calypso associates you can bring in part-time or full-time, working inside your processes. Deepest where it matters most: platform security and QA. Proven over a six-year Calypso engagement.

Gunadhya provides specialist Calypso consulting, security and QA services for capital-markets institutions. We're not a glossy systems integrator with a deep bench — we're a small, senior pool of experienced Calypso associates you can bring in part-time or full-time, working inside your processes, tools and management. Where we go deepest is platform security and quality assurance. Our credibility is hands-on: a six-year engagement on Calypso platform, where a three-month brief to fix SQL vulnerabilities grew into end-to-end security scanning and remediation across 100+ modules — plus a Calypso, Java and security-testing staffing engagement with Quinnox.

What we do — three Calypso pillars

1. Calypso Consulting & Staffing

A small pool of experienced Calypso associates — developers, technical leads and QA — available part-time or full-time, working under your processes and management.

Senior Calypso developers, technical leads and QA professionals
Experience across trading, risk, back-office, integrations and upgrades
Flexible engagement: short-term sprint support or long-term capacity
Ideal for BAU support, enhancements and capacity scaling
Proven with Quinnox — Calypso, Java and security-testing resources integrated with minimal ramp-up

2. Calypso Security Services

End-to-end security and vulnerability remediation for the Calypso platform — the core of our six-year Calypso engagement.

Vulnerability identification and remediation across a complex database layer and large file count
Third-party / dependency (jar) management — a repeatable process to stay secure as new CVEs surface
Automated security scanning with Veracode, Checkmarx, NexusIQ and SonarQube
Minimal-impact framework hardening that strengthens the platform without breaking functionality
Penetration testing and compliance-oriented security reviews

3. Calypso QA

Functional, regression and automation testing built for capital-markets logic — where "it works" means "it reconciles."

Functional testing across trading, risk and back-office workflows
Regression automation so upgrades and releases stay safe
Test coverage that understands financial instruments and trade lifecycles, not just screens
Tooling: Selenium WebDriver, REST Assured, JMeter, Cucumber, JUnit
QA embedded in your release cadence, or run as a scoped testing pass

Quinnox Engagement

We partnered with Quinnox to provide domain-expert Calypso staffing alongside Java and security-testing resources. Our Calypso professionals brought working knowledge of financial instruments and trade workflows, integrated with Quinnox's internal teams with minimal ramp-up, and helped accelerate delivery while strengthening platform security.

Frequently Asked Questions

Q: Do you provide Calypso consultants on a part-time or full-time basis?

Yes — that's our primary model. We have a small, senior pool of Calypso developers, technical leads and QA professionals available either part-time or full-time, working inside your processes and management.

Q: Do you do Calypso security and vulnerability remediation?

It's our deepest strength. We ran end-to-end security scanning and third-party vulnerability remediation across 100+ Calypso modules over a six-year engagement, using Veracode, Checkmarx and NexusIQ.

Q: Can you handle Calypso QA and test automation?

Yes. We provide functional, regression and automation testing built for capital-markets logic — trading, risk and back-office workflows — using Selenium WebDriver, REST Assured, JMeter, Cucumber and JUnit. We embed in your release cadence or run a scoped testing pass.

Q: We need to scale a Calypso team quickly — can you help?

Yes. We did exactly this for Quinnox, integrating Calypso, Java and security-testing resources with minimal ramp-up. Tell us the skills gap and cadence; we scope and staff directly.

Q: Can you take a whole piece off our plate instead of just supplying people?

Yes — that's our Managed Calypso Deliveries model: a dedicated team owns a scoped enhancement, upgrade or security initiative end to end, with governance and reporting, and hands it back clean.

Q: Are you a certified Calypso partner?

No — we're independent, specialist Calypso consultants with proven, hands-on experience on Calypso platform. That means senior people, direct access and no partner-tier overhead.
