I'm a principal-level engineer with a decade of Fortune 500 enterprise experience. I build backends, APIs, and data infrastructure on fixed-scope contracts. No hourly billing. No standups. Just shipped code.
6 months
Average time a dev agency quotes for an MVP backend
$80-150k
Average agency cost for backend + API + auth + payments
3-5 devs
Typical team size, most of whom are juniors
The agency model is broken. You're paying for a project manager, weekly standups, and a team of juniors doing what one senior engineer with the right tools can do faster and better. I cut that overhead entirely.
Services
Fixed scope. Async execution. Production-grade architecture.
For funded founders who need a real backend, not a prototype
You have a product idea and maybe a Figma file. I build the complete backend: database schema, API, authentication, payment integration, and deployment infrastructure. You get a production system, not a demo.
Typical timeline: 2-4 weeks
Pricing shared after scope review
For design and product agencies who need a backend partner
You handle the client relationships and design. I handle the engineering. Your clients never know I exist. You expand your capabilities without hiring a backend team.
Availability: 1-2 agency partners at a time
NDA-first. References available.
Process
I work asynchronously. You get more engineering hours and fewer meetings.
Email me your product requirements, Figma files, or technical spec. I'll review and respond with a scope document and timeline within 48 hours.
You get a fixed-scope proposal with clear deliverables, timeline, and flat-rate pricing. No surprises. No hourly tracking.
I work heads-down in my stack. You get async progress updates via your preferred channel: Slack, Linear, email, or GitHub.
Deployed, documented, and transferred to your repo. I stick around for a support window to handle any edge cases.
Proof of Work
Most contractors have portfolios. I have live products with real users.
SteadyDoor
Property maintenance logistics for landlords. Ticket management, property tracking, vendor dispatch, and tenant portal.
Staj
Automated gig payment splits for musicians. Bandleaders create gigs, allocate cuts, and Stripe distributes each member's share directly to their bank.
CivicBeacon
Civic engagement app tracking 14,000+ bills across Congress. Vote tracking, representative lookup, AI-powered plain-language bill summaries, and election tools.
Three products. Three different domains. All designed, built, and deployed by one engineer.
I don't chase trends. I use what I know makes production systems reliable, fast, and maintainable. One stack, mastered. Not ten technologies at a surface level.
About
I'm Daniel. I spent ten years building production systems at Fortune 500 companies across fintech, travel, and cloud infrastructure. The kind of systems that handle millions of transactions and can't go down.
That experience taught me how to build things right. AI tooling taught me how to build them fast. The combination means I can deliver in weeks what used to take a team of five several months.
I started PrimeStack Solutions to do this independently. Build real products for founders who need velocity, and partner with agencies who need a backend engineer they can trust.

Enterprise Background
Email me a brief: what you're building, where you are, and what you need. I'll respond within 48 hours with an honest assessment of whether I'm the right fit.
No sales deck. No discovery call. Just a straight answer.
