Engineering Practices & Solutions

Six core practices.
One accountable team.

From cross-platform mobile apps and cloud-native web architectures to production AI models, audited smart contracts, and zero-trust security. We ship turnkey systems with direct engineering accountability.

01 / mobile-development

Mobile App Development (iOS & Android)

High-performance native and cross-platform mobile apps using Swift, Kotlin, Flutter, and React Native. Built with offline-first local databases, resilient real-time synchronization, biometric security, and full App Store and Google Play automated CI/CD.

Typical engagement: 6–12 weeks to release · From $28,000
what you get — deliverables
Cross-platform Flutter / React Native or native Swift/Kotlin clean codebase
Offline-first SQLite/WatermelonDB sync with automatic conflict resolution
Automated Fastlane pipelines for TestFlight and Google Play internal testing
Push notification orchestration, deep linking, and analytics telemetry
02 / web-development

Website & Web Application Development

Modern, responsive web applications and enterprise SaaS platforms built with React, Next.js, and TypeScript. Optimized for sub-second Core Web Vitals, accessible design systems, resilient serverless backends, and internationalization.

Typical engagement: 4–10 weeks · From $24,000
what you get — deliverables
Modular React/Next.js architecture with SSR, ISR & edge caching
Accessible, token-driven design system with 100/100 Lighthouse performance
Headless CMS / API integration with GraphQL and robust offline caching
Zero-downtime deployment pipelines with Vercel, AWS CloudFront, or Docker
03 / devops-cloud

DevOps & Cloud Infrastructure Solutions

Resilient multi-cloud foundations on AWS, GCP, and Azure. We automate provisioning with Terraform IaC, containerize microservices with Kubernetes, and build zero-friction GitOps delivery pipelines so releases become routine non-events.

Typical engagement: 4–8 weeks · From $20,000
what you get — deliverables
Production Kubernetes (EKS/GKE) clusters with autoscaling and GitOps (ArgoCD)
Clean, modular Terraform scripts checked directly into your repository
Automated canary releases, blue-green traffic splits, and instant rollbacks
Comprehensive Prometheus, Grafana, and OpenTelemetry observability
04 / applied-ai

AI & Machine Learning Solutions

Custom LLM agent workflows, production-ready Retrieval-Augmented Generation (RAG), and proprietary fine-tuned models. We build automated benchmark harnesses to verify hallucination limits and citation precision on your private data before rollout.

Typical engagement: 6–10 weeks · From $30,000
what you get — deliverables
Multi-turn autonomous agent architectures with tool calling & human-in-the-loop
High-speed vector search (pgvector/Qdrant) with hybrid BM25 and semantic reranking
Continuous evaluation harnesses testing precision, safety, and citation accuracy
Enterprise PII sanitization boundaries and prompt injection guardrails
05 / blockchain-web3

Blockchain & Web3 Engineering

Battle-tested smart contracts, decentralized applications (dApps), and protocol engineering. We write gas-optimized Solidity and Rust contracts with formal verification, multi-sig governance, and seamless Web3 wallet integrations.

Typical engagement: 6–12 weeks · From $32,000
what you get — deliverables
Audited EVM / Solana smart contracts with automated Foundry test suites
Responsive dApp frontends integrating Wagmi, Viem, and WalletConnect
Multi-signature treasury protocols, automated escrow, and tokenomics logic
Comprehensive third-party security audit preparations & gas benchmarking
06 / cybersecurity-compliance

Cybersecurity, DevSecOps & Compliance

End-to-end security posture engineering. From thorough penetration testing and automated vulnerability scanning in CI/CD to Zero-Trust network architecture and rapid SOC2 / ISO 27001 compliance audit readiness.

Typical engagement: 2–6 weeks · From $15,000
what you get — deliverables
White-box & black-box penetration testing with detailed remediation roadmaps
Shift-left DevSecOps with automated SAST/DAST & dependency CVE scans
Zero-trust network segmentation, audited IAM privilege policies & KMS encryption
Full technical compliance gap analysis & documentation for SOC2 / ISO 27001
