Engineers of record for sub-second production systems.

A small, senior team with one obsession: build infrastructure that feels instant, survives chaos drills, and actually converts the ad spend you already burn. We translate field notebooks, Datadog graphs, and founder voice notes into systems that pass compliance frameworks, Core Web Vitals, and the vibe check.

The Team

Senior engineers with deep expertise across the full stack. No project managers. No account reps. The people scoping your system are the people writing the code.

Marcus Chen

Senior Frontend Engineer

8+ Years Experience

Frontend engineer obsessed with render performance and conversion engineering. Specializes in Astro, React, TypeScript, and building interfaces that load before users finish blinking. Deep knowledge of Core Web Vitals optimization, accessibility standards, and the intersection of design and page speed.

Has shipped high-converting marketing sites, SaaS dashboards, and ecommerce storefronts with sub-second load times across every device class. Runs A/B tests like lab experiments and treats every layout shift as a personal insult.

Sofia Reyes

Backend & Infrastructure Engineer

7+ Years Experience

Backend engineer who builds the APIs, data pipelines, and integration layers that hold everything together. Node.js, Python, PostgreSQL, Redis, and a near-religious commitment to structured logging. Handles EHR integrations, payment APIs, and third-party data syncs that need to work at 3 AM without human intervention.

Came up through healthcare tech, building HIPAA-compliant systems for multi-location practices. Now applies that same paranoid-about-data-integrity mindset to ecommerce inventory APIs, SaaS billing systems, and legal intake workflows.

From the Build Log

Pulled from voice memos and late-night Slack threads. Imperfect audio, perfect reminders of why we ship the way we do.

Voice memo, transcript

Daniel, 11:42 pm

"If we can't explain the failover plan on a whiteboard in five minutes, we don't understand it well enough to automate it."

Background: AWS us-east-1 rehearsal with a physical runbook spread across the dining table.

Slack thread

Marcus, after a deploy

"LCP went from 2.8s to 0.9s. The client's Google Ads rep called them asking what changed. That's the review I want."

Law firm site rebuild. Quality Score jumped 3 points in the first week.

Our Approach

Systems Thinking

We approach every project holistically. Understanding failure modes, designing redundancy, planning monitoring and recovery from day one. Software architecture is about building resilient systems that operate reliably in the real world, not just features that demo well.

Performance Under Pressure

Systems fail. Networks partition. Traffic spikes. We design for it. Load testing, chaos engineering, comprehensive observability, and automated recovery are standard. Your infrastructure should handle production pressure systematically, predictably, and safely.

Precision Engineering

We do not over-engineer. We identify the exact points of maximum leverage and optimize there. Database indexes that matter. Caching strategies that work. API endpoints that scale. Every optimization is measured, tested, and validated against real-world metrics.

Long-Term Maintainability

Clean code. Clear documentation. Version control. CI/CD pipelines. Automated testing. Type safety. We build systems that other engineering teams can understand, maintain, extend, and deploy confidently without emergency calls at 2 AM.
