Engineer-led,
run like an agency.

Hi — I'm Marques Smalley, the founder and (currently only) engineer behind MarqCode.
Over the last five years I've shipped software across startups and agencies — Creative Mines, Deksia, Kikcit, BizStream, and Clicki Referrals — building serverless SaaS platforms, AI-powered tools, mobile apps, and CMS-driven marketing sites.
MarqCode brings that experience into a lean, founder-led agency: senior-level engineering without the overhead, straight-line conversations with the person actually writing the code, and a real process from consult to launch.
AI automation & workflow tooling
OpenAI-driven pipelines, webhook orchestration, scheduled jobs.
CMS + marketing site builds
Storyblok, Kentico, headless setups for non-developers.

[ Services ]
Three ways we move fast.
Every engagement starts with a short consult and clear scope. No fixed packages — the work is shaped to the problem.
Custom Software
Full-stack web applications built to your business — not bent around someone else's template.
- Web apps & dashboards
- APIs & integrations
- Long-term maintainability
AI Integrations
Ship AI features that actually help — LLM pipelines, RAG, and assistants wired into your product.
- OpenAI / Claude / Gemini
- Custom copilots
- Data-aware chat & search
Workflow Automation
Replace the manual, repeat-every-week tasks with reliable jobs that run themselves.
- Scheduled pipelines
- Third-party API glue
- Zero-cost serverless CI/CD
[ How it works ]
A clear process, start to finish.
Every client engagement follows the same core process, regardless of service type.
- 01
Consult
Initial conversation with the client to understand their business, goals, and pain points.
- 02
Gather Requirements
Deep-dive into the specific business requirements for the project — what needs to be built, who will use it, and what problems it solves.
- 03
Architect the system
Shape the system design — data models, interfaces, and how the pieces fit together — before locking in tools.
- 04
Choose Tech Stack
Founder selects the appropriate technologies for the project based on scope, complexity, and long-term maintainability.
- 05
Plan & Map Features
Features are scoped and mapped out — what's in v1, what's a future phase, and how the work will be sequenced.
- 06
Develop
Build the software using the chosen stack, with regular check-ins and incremental progress you can see.
- 07
Deploy
Ship the project to production with monitoring, hosting, and everything needed to go live.
- 08
Iterate
Ongoing refinement and feature additions based on client feedback and evolving business needs.

What I Learned Building a Lake House Booking System
A modular monolith, a Postgres exclusion constraint, an RLS leak, and two paths to the same reservation: lessons from building Brookes Bayou.
