Backends that handle 10k–100k req/sec without buckling.
High-performance backends, AI automation, and microservices migrations for funded startups and mid-market teams that have outgrown their stack.
Drag the load up to watch the system autoscale and absorb it. Hover any node for live stats. Simulated, not a stock graphic.
You're not here because everything is fine.
You're here because something is breaking, costing too much, or eating your team alive.
Your system slows down every time you grow.
Traffic spikes take you down. Every new user makes the bill worse, not better.
Your team wastes 20+ hours a week on manual work.
Copy-paste, reconciliation, data entry: work an AI agent should be doing instead.
Your last agency disappeared after launch.
No tests, no docs, no one who understands the code. You inherited the risk.
Five things, done at a senior level.
Outcomes first. Stack as proof.
The numbers we hold ourselves to.
infra cost reduction
req/sec sustained throughput
test coverage standard
verified 5-star Upwork hours
Outcomes, not screenshots.
Real systems we took from breaking under load to shipping measurable results.
Transparent. Senior-only.
No juniors learning on your dime. You see the code, not just status updates.
Discovery & Proof of Concept
We map your bottleneck, agree on the target numbers, and ship a working PoC. No 40-page decks.
Agile Build
Two-week sprints, senior engineers only, demoable progress every cycle. You see the code, not just status updates.
Optimization, Security Audit & Handoff
Load testing, OWASP Top 10 pass, docs, and a clean handoff. You own the system, not a black box.
Depth where it matters.
Backend, infra, AI, data pipelines, streaming, and real-time telephony — chosen for the outcome, not the resume.

What most agencies hide, we lead with.
If your last vendor couldn't show you these, that's the problem.
80%+ test coverage
Unit and integration tests ship with the code. Not an afterthought.
OWASP Top 10
Every build is checked against the OWASP Top 10 before it goes live.
Load tested before launch
We prove the throughput numbers under load, so you don't find out in production.
Secrets management
No credentials in code. Proper vaulting and rotation from day one.
What our clients say.
Before working with CapregSoft, we struggled to present a professional and client-friendly digital presence. Their team delivered an intuitive and well-structured website that allowed us to communicate effectively with our clients and implement responsive integrations that enhanced overall engagement.
Dr. Zain Masood
Assistant Manager
The app sparked interest in the market and attracted initial users, while receiving no complaints about its functionality or usability. CapregSoft excelled at addressing user experience concerns, communicating clearly, and investing in the project's potential

We're probably not a fit if…
We say no often. It's how we keep the work senior and the outcomes real.
- ✕You want a cheap WordPress site.
- ✕You need a frontend-only project with no backend.
- ✕You're looking for legacy maintenance (COBOL/FORTRAN).
- ✕You want your whole app built for $2k.
Questions teams ask before they reach out.
What does CapregSoft do?+
CapregSoft is a senior backend and AI engineering agency. We build high-performance Golang backends, AI automation that removes repetitive manual work, real-time data pipelines, and zero-downtime monolith-to-microservices migrations for funded startups and mid-market teams.
How much does a project cost?+
Engagements start with a free 30-minute discovery call and a 1–2 week discovery and proof-of-concept phase that ends with a fixed estimate before you commit. Pricing depends on scope, which we size together on the call so there are no surprises.
How fast can you start, and how long do projects take?+
Most engagements open within a week or two. Because we ship in two-week sprints and migrate or build incrementally, you see working software early instead of waiting months. AI automations often pay back in 2–3 months; migrations typically run 3–6 months depending on scope.
What makes CapregSoft different from other agencies?+
Senior-only delivery: the engineer who scopes your work is the one who ships it, with no juniors learning on your budget. Every build includes 80%+ test coverage, an OWASP Top 10 security pass, and load testing to prove the numbers before launch. You own all the code and documentation.
Do you work with teams outside your time zone?+
Yes. We work with funded startups and mid-market companies worldwide, with overlap hours arranged around your team. Communication is async-friendly and transparent: you see the code and demoable progress, not just status updates.
