For Engineers

// about dev-core dev-core is a software agency formed by a team of engineers with deep, hands-on experience across web platforms, mobile applications, cybersecurity, microservices architecture, and server infrastructure.

We don't just write code — we engineer systems. Every solution we ship is built with precision, tested under pressure, and designed to outlast the hype.

Core Expertise

What We've Mastered

Years of hands-on experience across five critical domains of software engineering.

01
Web & API Development

We build everything from fast-loading marketing sites to complex enterprise platforms and RESTful microservices. Our stack spans .NET, Node.js, Next.js, and PHP — chosen for the right job, not just the familiar one. We architect APIs that are scalable, versioned, and documented from day one.

02
Mobile App Development

Cross-platform and native mobile apps built for real-world performance. We use Flutter for consistent cross-platform UX and Kotlin/Java for Android-native power. Our apps handle offline sync, push notifications, background jobs, and biometric auth without cutting corners.

03
Penetration Testing

We find vulnerabilities before attackers do. Our security team conducts structured, methodology-driven penetration tests across web applications, APIs, network infrastructure, and operating systems. Reports come with CVSS scores, reproduction steps, and a prioritized remediation roadmap.

04
Microservices Architecture

We design distributed systems that scale independently, fail gracefully, and communicate reliably. We build microservices using ASP.NET APIs, Node.js, and Rust for performance-critical services. Event-driven architectures, API gateways, service discovery, and containerized deployment are part of every design.

05
Server Administration & Infrastructure

End-to-end server lifecycle from bare metal to production-hardened environments. We provision, harden, monitor, and maintain Linux and Windows servers. Experience spans Nginx/Apache configuration, firewall rules, SSL management, automated backups, performance tuning, and incident response. We don't hand off a server — we keep it running.

Our Principles

How We Think

01
Engineering First

We approach every project as an engineering problem, not a feature list. Architecture decisions are made before a line of code is written. We build foundations, not patches.

02
Security by Default

Security isn't a checkbox — it's a discipline embedded throughout development. Every project we build gets assessed through a security lens, whether it's a web app or a server deployment.

03
Ownership & Transparency

We take full ownership of our work. No blame, no hand-offs. You get direct communication, honest timelines, and a team that stays accountable through delivery and beyond.

04
Right Tool, Right Job

We're not locked into any single stack. Rust for performance-critical services, Python for scripting and automation, .NET for enterprise APIs — we choose based on requirements, not habit.

05
Built to Last

Code quality isn't optional. We write tested, documented, maintainable code — because every project we ship will outlive the initial sprint. Refactoring debt compounds; we minimize it from the start.

06
Continuous Learning

The tech landscape shifts fast. We invest in continuous learning, conduct our own security research, and keep our tools updated. What we knew last year is the baseline, not the ceiling.
