Why HD Labs
The HD Labs Difference
Engineers who build and run production systems for capital markets, financial
services, banking and enterprise. The people you talk to are the people writing your code.
20+Years in financial systems
Experience From Real Markets
Our engineering comes from market data at the New York Stock Exchange,
Interactive Data and Yahoo Finance, and from the payment, card and blockchain
platforms built since. We design for the busy day, the failover and the missing message from the start.
Week 1Code in your repo
Progress You Can See
A written scope and architecture in the first week, then weekly releases
into your own repository. You see working software every week, and you own all of it.
100%Senior-reviewed code
Senior Engineers on Every Line
A senior engineer designs the architecture and reviews everything that ships.
AI tools take care of routine code, so more of that time goes to edge cases,
testing and correctness.
What We Build
Engineering Pillars
Capital markets, financial services and enterprise systems first, backed by
cloud & DevOps, AI and blockchain. All shipping production code.
// Fast, complete, never out of order.
Capital Markets & Market Data
Real-time market data feeds, low-latency systems and trading-platform
integrations, from an engineer who built market data systems at the
New York Stock Exchange, Interactive Data and Yahoo Finance.
// Every transaction correct. Compliance included.
Financial Services & Banking
Payments, card platforms, banking API integrations, ledgers and transaction
workflows. We handle the hard parts — reconciliation, KYC flows, multi-rail
transactions, regulatory constraints — so you don't have to.
Banking APIsStripe · ACHCard ProcessingFinancial Data APIsStablecoin RailsKYC / AML flows
Scalable APIs, microservices, event-driven architecture, and distributed
systems built for reliability. We design for the load you'll have, not just
the load you have today.
Cloud architecture and migration on AWS and GCP, primary and backup
regions with tested failover, event-driven services, CI/CD and
Infrastructure as Code.
We embed AI tools — Claude, Copilot, Cursor — at every stage of development.
Not as gimmicks, but as genuine force multipliers for our engineering team.
The result: production-ready code in a fraction of the typical time.
AI-assisted codingAuto test generationRapid prototypingArchitecture guidanceAI-generated docs
Smart contracts, dApps, tokenization platforms, and blockchain integrations
into existing enterprise systems. We work across Ethereum, Polygon and Solana:
production grade, auditable, and maintainable.
AI tools are embedded at every stage — not bolted on as an afterthought.
We scope clearly, architect deliberately, build fast, and ship with confidence.
01
Scope
Deep discovery call. We define what to build,
what not to build, and why. No ambiguity in the brief.
AI-assisted requirement analysis
02
Architect
System design reviewed by senior engineers.
AI tools help us explore trade-offs and validate
architectural decisions faster.
AI-accelerated design iteration
03
Build (AI-Assisted)
Engineers write production code with AI as a force multiplier.
Automated test generation, documentation, and code review
baked into the workflow.

Ship
CI/CD pipelines, automated testing, deployment to your
infrastructure. You own the code. We hand off clean,
documented, maintainable systems.

Technology
The Stack We Ship With
Chosen for production reliability. Every tool here is one we use in client work.
We measure success in outcomes, not deliverables.
Here's what shipping looks like.
Financial Services
Multi-Rail Payment Platform
Challenge: Legacy payment system unable to support multi-rail
transactions across fiat, ACH, and crypto simultaneously.
Built event-driven microservices architecture integrating Stripe, ACH,
and crypto payment rails on a shared ledger abstraction. Deployed on
Kubernetes with full observability stack.
Challenge: Monolithic Java application hitting hard
throughput limits under peak load, blocking product expansion.
Decomposed into NestJS microservices with Kafka event bus and Redis caching.
Zero-downtime migration using strangler-fig pattern with full CI/CD rebuild.
Latency: Why Microseconds Matter, and How Exchanges Keep It Fair
In trading, being a few microseconds late means acting on an old price. Where latency comes from, who it hurts, and what exchanges do so that speed doesn’t turn into an unfair advantage.
In under a second your app says Executed, but the shares arrive the next working day. Here is the whole trip: your broker, the exchange’s order book, the clearing corporation and the depository.
Three very different designs all promise “one coin, one dollar”. What holds each one there, and what happened in 2022 and 2023 when two of them slipped.
