Architecture-first delivery
A solution architect joins on day one, owns the C4 model and ADR log, and runs an explicit threat-modelling pass before a line of production code is written. No surprise rewrites in month nine.
Services
Enterprise Software Development Services for US & EU Operators
YuSMP Group builds custom enterprise platforms for mid-market and Fortune 1000 operators — regulated workloads, multi-system integrations across ERP, CRM, and IDP, and engagements that start at 250k EUR. GDPR, SOC 2 Type II (in progress), and ISO 27001 controls are nailed down before kickoff, and every engagement runs with a named project sponsor and an executive steering committee on both sides. Senior engineers only, Yerevan delivery, CET hours.
Enterprise-grade software is a different shape of work from a startup MVP. The platforms we build for mid-market and large operators run for three-to-five years and longer, carry regulated data (financial, health, energy, government), and live inside an integration sprawl — ERP, CRM, IDP, data lake, dozens of internal systems — with high SLA and availability targets. We staff senior engineers, a named solution architect, and a dedicated security lead, run inside your governance model rather than around it, and ship to compliance audit standards from day one. GDPR-aligned, ISO 27001 ready, SOC 2 Type II in progress, HIPAA-capable, PCI DSS scope on request.
What's inside an enterprise engagement
Integration with your enterprise stack
SAP S/4HANA, Oracle EBS, Salesforce, Workday, ServiceNow, Okta, Active Directory / Entra ID, MuleSoft, Boomi. We respect freeze windows, your iPaaS standards, and your data contracts.
Compliance posture
GDPR-aligned, SOC 2 Type II in progress, HIPAA-capable, PCI DSS scoped on request, ISO 27001 ready. Evidence flows directly into your auditor's workpapers without slowing the release train.
High availability + SRE
Stated RTO and RPO targets, multi-region active-active or active-passive deployments, tested DR runbooks on a quarterly cadence, 24/7 on-call with documented severities and post-incident reviews.
Audit-ready engineering
Formal change management, separation of duties between developers and approvers, signed commits, dual-approval production deploys, and traceable approvals from Jira ticket to artifact hash.
Procurement-friendly
Standard MSA, written SLAs, GDPR DPA, BAA on request, completed CAIQ and SIG Lite, sub-processor register, professional indemnity and cyber insurance — everything your vendor risk team asks for.

How we deliver enterprise engagements
-
01
Discovery
Six-to-eight week architecture pass: C4 model, integration map, threat model, compliance gap analysis against your SOC 2, ISO 27001, HIPAA, or PCI DSS scope, and a written delivery plan signed off by the steering committee.
-
02
Foundation
CI/CD pipelines, security baseline (SAST, SCA, container and IaC scans), environments (dev, stage, pre-prod, prod), secrets management in Vault, observability with Datadog or Splunk, runbooks in place before feature work starts.
-
03
Build
Quarterly release trains, mandatory code review with separation of duties, change management aligned to your CAB, freeze-window discipline, and audit evidence produced as a byproduct of normal delivery rather than as a fire drill.
-
04
Run
SRE squad, 24/7 on-call, quarterly DR tests, capacity planning tied to your business forecast, support during external audits, and a feature stream that keeps shipping while the platform stays available.
Engagement models
Fixed Price
For scoped modules with hard regulatory deadlines — SOX module, PCI DSS scoped service, GDPR data-subject portal — with audit gates and milestone-based invoicing.
Time & Materials
Default model for enterprise build phases. Monthly invoicing per role and seniority, transparent timesheets, full visibility on capacity and outcomes through quarterly business reviews.
Dedicated Team
Long-running platform squad with an embedded engineering manager, solution architect, and security lead. The team you onboard at month one is the team you have at year three.

Why US & EU operators pick YuSMP for enterprise
GDPR-aligned · ISO 27001 ready · SOC 2 Type II in progress · HIPAA-capable · PCI DSS scope on request · CCPA-acknowledged
Compliance-ready
Evidence packs, control mappings, and audit support are part of the engagement, not an afterthought. We have walked auditors through SOC 2 and ISO 27001 reviews alongside client security teams.
Architecture-first
Every enterprise engagement begins with a named solution architect, an explicit C4 model, ADR log, and threat model. Decisions are written down and reviewed by your steering committee before the build phase opens.
EU jurisdiction + US client coverage
Delivery entities in Cyprus and Armenia, EU data residency, US options on request, CET workday with guaranteed 9 AM–1 PM ET overlap for US East-Coast steering meetings and incident response.
For payments, lending, and healthcare platforms we run inside PCI DSS and HIPAA scope and align directly with your QSA, security officer, or external auditor on access, logging, segregation of duties, and minimum-necessary data handling.
Frequently asked questions
Do you sign MSAs and DPAs with enterprise procurement?
Yes. We sign Master Services Agreements with US and EU procurement teams as standard, including DPAs under GDPR Article 28, BAAs on request for HIPAA workloads, and standard contractual clauses for cross-border data. We complete vendor security assessments (CAIQ, SIG Lite, custom questionnaires), supply evidence packs for ISO 27001 controls, and accept enterprise-specific clauses on IP assignment, audit rights, sub-processor approval, insurance, and termination. Average legal cycle for a Fortune 1000 MSA is four to six weeks.
What does your SOC 2, ISO 27001, GDPR posture look like in practice?
GDPR-aligned across all delivery: EU data residency, named DPO contact, breach notification SLAs in writing. ISO 27001 ready with an internal ISMS, asset register, access reviews, and quarterly risk assessment. SOC 2 Type II is in progress with a Big-Four-grade auditor. For your engagement we map controls one-to-one against your own SOC 2 or ISO scope, run engineers on managed endpoints with SSO, MFA, encrypted disks, and isolated repositories, and feed evidence directly into your audit workpapers.
How do you integrate with SAP, Salesforce, Workday, Okta?
We staff integration engineers who have shipped to SAP S/4HANA (OData, IDoc, BAPI), Salesforce (Apex, Platform Events, Connect), Workday (RaaS, REST), Okta (SCIM, SAML, OAuth2), and Active Directory / Entra ID. Standard pattern is an event-driven integration layer (Kafka or RabbitMQ) with idempotent consumers, schema registry, and a dedicated integration test suite that runs against vendor sandboxes. We respect change windows, freeze periods, and your existing iPaaS (MuleSoft, Boomi, Workato) where one is in place.
Can you run high-availability platforms with multi-region failover?
Yes. We design and operate platforms with stated RTO and RPO targets, multi-region active-active or active-passive deployments on AWS, Azure, or GCP, and DR runbooks tested on a quarterly cadence. Standard primitives: Kubernetes across two regions, managed Postgres or Aurora with cross-region replication, Kafka MirrorMaker 2, infrastructure as code in Terraform, secrets in Vault, observability via Datadog or Splunk. On-call coverage is 24/7 with documented incident severities and post-incident reviews.
How do you handle change management and audit traceability?
Every change is traceable from ticket to production: signed commits, mandatory code review with separation of duties, automated security scans (SAST, SCA, container, IaC), CI/CD gates, and approvals recorded in Jira and Git. Production deploys require dual approval and are logged with timestamp, actor, and artifact hash. We integrate with your change advisory board, respect freeze windows, and produce evidence on demand for SOX, SOC 2, ISO 27001, PCI DSS, and HIPAA audits without slowing the release train.
What is the typical enterprise engagement size and timeline?
Enterprise engagements start at 250k EUR for a scoped phase and routinely run 1–5M EUR over the platform lifetime. A typical shape: a six-to-eight week discovery and architecture phase, a six-to-nine month build to first production release, then a long-running run phase with an SRE squad and a feature stream. Teams sit between eight and twenty-five engineers with an embedded solution architect, security lead, and engineering manager. We commit to named seats, transparent monthly invoicing, and quarterly business reviews.
