Everything a serious software house can deliver—with AI and security first.
Green Cyber City partners with founders and enterprises to conceive, engineer, operate, and harden digital products. AI and cybersecurity are our lead capabilities because they underpin trust, competitiveness, and long-term viability in modern software stacks.
Priority capabilities
When your roadmap hinges on intelligent automation or unacceptable risk gaps, anchor the program here. Depth of content beneath each pillar reflects how we scope, staff, and govern those engagements day to day.
Artificial Intelligence & Intelligent Products
From practical copilots to production-grade ML — we help you ship AI that is measured, governable, and aligned with your risk profile.
Our software house treats AI as part of the product, not a demo. We work with retrieval-augmented systems, embeddings pipelines, labeling workflows, evaluation harnesses, and human-in-the-loop reviews so outputs stay grounded. Whether you need customer-facing assistants, operational automation, or analytics that learn over time, we pair strong engineering with clarity on latency, cost, and compliance.
What we deliver
- LLM integrations, prompts, tooling, and safe-by-design guardrails for support, sales ops, and internal knowledge
- RAG architectures, chunking strategies, citation surfaces, and content freshness workflows you can audit
- Classic ML pipelines: feature stores, batch & online inference services, monitoring, drift detection, rollback paths
- Workflow automation across CRMs, ticketing, spreadsheets, and custom admin surfaces — measurable time saved
- Partnering with your security stakeholders on model access policies, secrets handling, and data residency expectations
Cyber Security & Secure Engineering
Defense in depth baked into delivery — architecture reviews, hardened APIs, identity, and pragmatic threat modeling.
Security is threaded through discovery, coding, CI, and releases. We help teams move fast without shipping fragile permission models or leaking sensitive data. Engagements range from greenfield secure design to hardening existing platforms: tightening authentication, secrets management, transport and storage encryption, dependency hygiene, and observability for suspicious activity. We speak the language of engineers and stakeholders alike so trade-offs are explicit.
What we deliver
- Secure SDLC habits: threat modeling light sessions, STRIDE-style checklists, and dependency & container scanning in CI
- Identity & access: OAuth2/OIDC patterns, role-based and attribute-based access, session hardening, API key lifecycle
- API & data protection: input validation, rate limiting, least-privilege database access, field-level sensitivity reviews
- Secrets, keys, and configuration: vault patterns, rotation, environment separation, and audit-friendly change logs
- Readiness for vendor reviews: documentation packs, control mapping narratives, and remediation backlogs you can execute
Full-stack delivery catalogue
Supporting practice areas integrate tightly with AI and cyber programs—sharing architecture reviews, release discipline, and product clarity—so engagements stay cohesive instead of fragmented vendor silos.
Custom Software & Product Engineering
End-to-end delivery of web, backend, and integrations — maintainable codebases that your team can extend for years.
We build flagship products for startups and modernize systems for enterprises. Typical work spans domain modeling, API design, background jobs, admin consoles, billing hooks, and third-party integrations. You get transparent milestones, pragmatic testing, and documentation that survives handoff.
What we deliver
- Domain-driven design workshops, backlog shaping, and technical spikes before major commitments
- REST and GraphQL services, message queues, idempotent workflows, and idempotency-ready integrations
- Admin consoles, impersonation-aware tooling, audit logs, and role separation for ops teams
- Hands-on mentorship and code review culture so junior engineers onboard quickly
Web Platforms & SaaS
Responsive, accessible experiences with SEO, performance budgets, and design systems under control.
From marketing sites that convert to multi-tenant dashboards, we prioritize perceived performance and accessibility as first-class outcomes. Stacks include modern SSR frameworks where they matter, component libraries tuned to brand, and edge-friendly asset strategies.
What we deliver
- Landing pages and growth sites tuned for Core Web Vitals and coherent visual language
- Authenticated SaaS surfaces with optimistic UI patterns, realtime where needed, and resilient error states
- Design-token-driven systems or integration with platforms like Figma for delivery parity
- Internationalization scaffolding, CDN configuration, and cache strategies that behave under traffic spikes
Mobile Applications
Cross-platform and native-aligned experiences with offline-aware flows where your users need reliability.
We deliver mobile slices of your platform with attention to biometric auth surfaces, secure local storage patterns, push notification flows, and store submission readiness. Sharing logic with backend contracts keeps divergence low across iOS and Android.
What we deliver
- React Native or native Swift/Kotlin deliveries depending on UX and performance thresholds
- Secure token storage, certificate pinning considerations, and biometric unlock paths
- Deep links, universal links, and analytics hooks without compromising privacy narratives
- Release train support: phased rollouts, crash analytics, and hotfix workflows
Cloud, DevOps & Reliability
Infrastructure-as-code environments, observable services, and release paths your on-call rotations can trust.
We blueprint environments that separate concerns and cost: production, staging, and ephemeral previews. Observability dashboards, alerting, and runbooks are part of shipping — not afterthought documentation. IaC favors reproducibility whether you anchor on Kubernetes, VPS, or managed PaaS.
What we deliver
- Dockerized services, IaC sketches (Terraform, Pulumi-aware), CI/CD pipelines with gated promotions
- Structured logging, traces, uptime checks, SLIs mapped to alerting that avoids noise floods
- Database migration strategies (blue/green-friendly), backup verification drills, failover notes
- Cost visibility: tagging, budgeting alerts, and right-sizing proposals after measured load phases
UX / UI Discovery & Delivery
From problem framing through high-fidelity UI — aligning user outcomes with engineering constraints.
Visual polish means little if workflows are ambiguous. We run lightweight discovery interviews, prototype critical flows, and pressure-test usability with measurable tasks before heavy build spend. Outputs layer cleanly into engineered components.
What we deliver
- Journey mapping, JTBD-informed workshops, and priority matrices for ruthless scope focus
- Wireframes progressing to clickable prototypes validated with stakeholder and user checkpoints
- Accessibility heuristics: contrast, semantics, keyboard paths, reduced motion respectful defaults
- Design-to-dev handoffs with annotated specs or token parity to reduce rework cycles
Quality Assurance & Test Automation
Regression defenses that evolve with velocity — unit, contract, integration, and targeted E2E coverage.
We treat tests as executable specifications. Pyramid-shaped strategies keep unit tests closest to domains, augment with contract checks between services, and deploy Playwright/Cypress arcs on the riskiest journeys. Release confidence grows without blocking teams on flaky suites.
What we deliver
- Test pyramid design: fast unit seams, pact-style contracts across service boundaries where teams split
- CI test fan-out patterns, flaky test quarantine etiquette, seed data hygiene for repeatable environments
- Performance probes: soak tests and load scripts that align with SLA conversations
- Accessibility smoke checks layered into pipelines for critical transactional screens
