Engineering Services & Diagnostic Audits

We operate on fixed-scope, high-impact engineering sprints with measurable performance and uptime deliverables.

01
Timeline: 2 business days

48-Hour Mobile & Web Performance Audit

For production applications suffering from frame drops, slow cold launches, battery drain, or memory crashes. We hook your build to Xcode Instruments, Android Studio Profiler, and Chrome DevTools under realistic throttled conditions.

Deliverable: Flamegraph profiling report + Video teardown + Prioritized pull requests
Key Technical Focus Areas
• Hermes GC pauses and React Native thread hopping
• Offscreen GPU rendering, alpha blending, and shadow overdraw
• Darwin kernel Jetsam memory limits and background termination bugs
• Unindexed SQLite queries and database lock contention
02
Timeline: 6 - 12 weeks

Greenfield Mobile Application Engineering

Ground-up architecture for mobile products where stability and responsiveness are critical. We pick the right stack (Native Swift/Kotlin or React Native) based on hardware requirements rather than trends.

Deliverable: Production iOS & Android apps in your repository with locked 120Hz performance
Key Technical Focus Areas
• Offline-first sync architectures with idempotent delta queues
• Native hardware integration (Bluetooth LE, audio DSP, sensors)
• Strict cold-start budgets (sub-1.2s median boot time)
• Automated App Store Review compliance from commit #1
03
Timeline: 4 - 8 weeks

High-Density Web Platform Engineering

For complex web platforms, data dashboards, and consumer storefronts where monolithic client-side JavaScript has compromised Core Web Vitals and conversion rates. Built with Astro and modern edge runtimes.

Deliverable: Zero-JS or island-hydrated web platform with sub-second TTI
Key Technical Focus Areas
• Replacing multi-megabyte single-page hydration blocks with selective islands
• Canvas-based telemetry rendering for high-frequency live data
• Edge-side caching and dynamic prefetching strategies
• Eliminating barrel-file cascade bloat
04
Timeline: 3 - 5 weeks

Architecture & Infrastructure Optimization

For teams paying disproportionate monthly infrastructure bills due to premature microservices, Kubernetes clusters, and cross-AZ transit fees.

Deliverable: Modular monolith architecture with up to 90% cloud cost reduction
Key Technical Focus Areas
• Collapsing fragile distributed services into clean, modular monoliths
• PostgreSQL connection pool tuning and query optimization
• Replacing costly managed queues with atomic transactional outboxes
• Eliminating runaway NAT Gateway egress charges
Fit & Scope

When We Are the Right Fit

Being upfront about our strengths ensures efficient, high-value engagements.

Engage Us If:

  • • Your mobile app has frame drops, memory spikes, or offline sync bugs that need deep profiling.
  • • You need a production-grade mobile or web MVP built from the ground up by senior engineers.
  • • You require full repository ownership with zero proprietary agency lock-in.
  • • You care about measurable user experience metrics: sub-second launches, 120Hz display consistency, and battery life.

We Are Not a Fit If:

  • • You are seeking the lowest-cost template assembly from offshore agencies.
  • • You want layers of non-technical project managers between you and the codebase.
  • • You need branding, graphic illustration, or advertising campaigns. We focus exclusively on software engineering.
  • • You are introducing complex microservices for an early product that would run reliably on a simple server.
