Engineering Depth

Technical Capabilities

Deep architectural systems, infrastructure patterns, and technical execution behind every commercial release.

Services vs. Capabilities

How clients engage me vs. what I engineer.

Services describe the commercial engagements you hire me for (Fractional CTO, MVP Sprints, SaaS Engineering, AI Codebase Rescue). Capabilities describe the deep architectural systems I execute behind those engagements. I do not compete on commodity framework logos; I engineer resilient, high-throughput systems.

Domain Capability

Web & Cloud Monoliths

Unified Modular Monoliths Over Microservice Sprawl

I design high-velocity Next.js and Node.js modular monoliths that eliminate distributed network latency and RPC synchronization overhead, while preserving strict domain boundary isolation.

Engineered Systems:
Server-Side Streaming & Partial Prerendering (PPR)
Domain-Driven Service Decoupling within Single Repositories
Edge Network Routing & Dynamic Geolocation Tailoring
Sub-50ms Global API Response Benchmarks
Applied Tools:
Next.js App RouterReact 19TypeScriptNode.jsVercel / Cloudflare
Domain Capability

Multi-Tenancy & Database Design

Kernel-Level Data Isolation with PostgreSQL RLS

I engineer multi-tenant B2B database architectures where cross-tenant data leakage is mathematically prevented by database kernel Row-Level Security (RLS) policies rather than fragile application-level WHERE clauses.

Engineered Systems:
PgBouncer Connection Pooling & Transaction-Mode Scaling
Tenant-Scoped Session Contexts & Dynamic Policies
Automated Schema Migrations across Shared & Dedicated Tiers
Read-Replica Query Routing for Reporting & Analytics

Domain Capability

High-Throughput Caching & Queues

Durable Background Workflows & Edge Invalidation

I design high-throughput caching and background-processing architectures where synchronous application requests would otherwise become the performance bottleneck.

Engineered Systems:
Redis Streams & BullMQ FIFO Job Workers with Dead-Letter Queues
Atomic Idempotency Locking for Webhook Ingestion
Stale-While-Revalidate Edge Tagged Cache Invalidation
Burst Absorption Buffers Handling 10,000+ Req/Sec
Applied Tools:
RedisBullMQAWS SQSCloudflare Workers KVFastify
Domain Capability

AI & LLM Infrastructure

Deterministic State Machines Around Non-Deterministic Models

I engineer reliable, production-grade AI applications by wrapping LLMs in Finite State Machines (FSMs) with strict Zod schema validation, semantic vector caching, and token budget circuits.

Engineered Systems:
Native LLM Structured JSON Schema Validation & Auto-Correction
Semantic Prompt Caching via Vector Cosine Similarity (40%+ cost reduction)
Sandboxed Tool Calling & Non-Destructive Mutation Proposals
Multi-Provider Failover Circuits (OpenAI ↔ Anthropic ↔ Mistral)
Applied Tools:
OpenAI SDKAnthropic APIZodRedis VectorLangChain (Triage)
Domain Capability

Mobile & Offline-First Systems

Zero-Latency Local Persistence & Conflict-Free Sync

I deliver 60fps native-feel cross-platform mobile experiences that work without network connectivity, persisting data locally in SQLite and reconciling conflict-free deltas upon reconnection.

Engineered Systems:
WatermelonDB / SQLite Local-First Reactive State Observables
Field-Level Last-Write-Wins (LWW) Three-Way Merge Engines
Resumable Chunked Binary Delta Uploads for Erratic Networks
Haptic Feedback & Gestural Micro-Interactions (Reanimated)
Applied Tools:
React NativeExpoWatermelonDBSQLite WASMFlutter
Domain Capability

High-Scale E-Commerce & Catalogues

Sub-30ms Faceted Search & Flash-Sale Cart Resiliency

I build e-commerce infrastructure supporting 500,000+ SKUs with multi-dimensional attribute filtering and atomic inventory reservation locks that prevent overselling during flash promotions.

Engineered Systems:
Pre-Computed Facet Inverted Indexes (Elasticsearch / Meilisearch)
Redis Atomic Decrement (DECR) Reservation Timers (10-min Cart Hold)
Decoupled Checkout Engines Resilient to Database Spikes
Global Stripe Billing, Metered Usage & Enterprise Invoicing
Applied Tools:

Security, Diligence & Governance

Audit-Ready Architecture & Complete IP Transfer

I prepare software platforms for investor technical due diligence, SOC2 readiness, and enterprise compliance, while guaranteeing 100% intellectual property transfer to the client.

Engineered Systems:
Role-Based Access Control (RBAC) & Enterprise SSO / SAML
Immutable Cryptographic Audit Logging for Financial Records
Automated CI/CD Vulnerability Scanning & Dependency Audits
100% Complete IP, Git Repo & Production Cloud Account Ownership Transfer
Applied Tools:
Auth0ClerkNextAuthGitHub ActionsTerraformAWS IAM
Absolute IP Ownership

You own the system.
The code. The infra. The data.

Software should not become valuable enough to matter and then be impossible for the client to own or operate.

Everything I build is 100% client-owned intellectual property from day one. You own the code, the accounts, the infrastructure, and the data. No vendor lock-in.

  • 01Source code & Complete Git Repositories
  • 02Apple, Google & Enterprise Developer Accounts
  • 03Cloud Infrastructure, VPCs & Production Databases
