Independent Software Engineering Studio
Build it.
Ship it.
Scale it.
SD Wares is an independent engineering studio. I take products from idea — or an AI-built prototype — to production, and keep them running: architecture, code, cloud infrastructure, scale, and operations. Backed by over 15 years of building systems that serve millions of users and billions of requests.
- ▸ Scaled API platforms handling 3B+ monthly requests
- ▸ Reduced infrastructure costs through caching, observability, and smart routing
- ▸ Led teams delivering production systems end-to-end
- ▸ 0 → 100: building full products from idea to live

Capabilities
System Architecture
Designing distributed systems that scale under real-world load — not just diagrams. From greenfield builds to breaking down monoliths, I focus on throughput, resilience, and long-term maintainability.
Cloud-Native Platforms
Production-ready cloud systems using Azure. Built for scalability, observability, and cost control from day one.
High-Scale APIs
Design and optimization of APIs handling high concurrency and large traffic volumes. Latency, caching, and failure handling are built in — not added later.
Engineering Leadership
Hands-on tech leadership: architecture decisions, mentoring, and delivery execution. I don’t just guide — I ship production code with the team.
Observability & Reliability (SRE)
Full visibility into your system: logs, metrics, alerting, and incident response. Systems designed to fail gracefully and recover fast.
AI Infrastructure & Agentic Systems
Designing backend systems for AI: LLM integrations, MCP architecture, tool orchestration, and cost-aware AI workflows.
Track Record
High-Scale Systems
Scaled API platforms handling 3B+ monthly requests with 99.9% uptime across distributed microservices architecture.
Cloud Architecture
Designed cloud architectures on Azure with high availability, fault tolerance, and automated failover capabilities.
Cost Optimization
Reduced infrastructure costs 30-40% through intelligent caching, observability-driven optimization, and smart routing strategies.
Technical Leadership
Led cross-functional teams delivering production systems end-to-end, from architecture design through deployment and monitoring.
Idea to Production
Building complete products end to end: spec, architecture, code, infrastructure, launch, and operations.
Idea → Production
You built it with AI.
I make it real.
Prototype in a weekend — then what? I take apps from idea, prototype, or vibe-coded repo to a product that survives real users, real traffic, and real bills.
Zero to Launch
The whole lifecycle in one pair of hands: spec, architecture, code, infra, launch. Fast delivery, senior-level judgment.
Vibe Code → Production Code
A deep code review of your AI-built app, then the fixes: auth, secrets, data isolation, tests — the parts the demo skipped.
Infra & Deployment
Cloud setup, infrastructure as code, CI/CD, one-command environments. Push to main, ship to prod.
Scale & Performance
Caching, query tuning, load testing, cost control. Ready for the day it takes off — not the day after.
Run It
Logs, metrics, alerts, runbooks. Operational from day one, not after the first outage.
AI Features, Done Right
LLM integrations, agents, and MCP tools with budgets, guardrails, and observability built in.
Every project below was built this way — idea to live, end to end.
Bring Me Your Project ↓Selected Projects
Meridian
One gateway for OpenAI and Anthropic. Less cost, less risk.
Change one URL and every AI request gets a budget, a cache, a fallback provider, PII redaction, and a price tag. Works with the OpenAI and Anthropic SDKs, Claude Code, and MCP clients. Now in open demo: request access, get a trial workspace with free credit, then bring your own keys.
Drop-In API
OpenAI- and Anthropic-compatible endpoints plus an MCP server. Keep your SDKs; change the base URL.
Budgets That Hold
Cost is reserved before each call, so parallel traffic can't overshoot a budget. Alerts at 80% and 100%.
Failover & Aliases
One model name, several providers. Retries, circuit breakers, and automatic fallback when a provider fails.
Exact & Semantic Cache
Repeated and similar requests answered from Redis, switchable per project.
PII Redaction & BYOK
Personal data masked before it reaches a provider, streams included. Bring your own keys, encrypted via Azure Key Vault.
Self-Service Portal
Organizations, projects, five roles, usage charts, and a "what if" simulator that reprices your traffic on every model.
Cloud Compliance Agent
Finds the problem. Opens the fix. Proves it.
An autonomous agent that audits an Azure subscription against the CIS Azure Foundations Benchmark, streams findings live, and proposes Bicep fixes as GitHub pull requests. Autonomy tiers and Slack approval gate every action; a hash-chained, replayable evidence trail backs every finding; an auditor-ready PDF closes the loop.
My Radio
One tap. Good music.
Curated chill, house, and jazz stations, plus thousands more from the world directory. Installs like an app on your phone and keeps playing with the screen off.
