PQ Angels builds web, desktop, and enterprise software and AI/ML integrated solutions for companies that need more than a templated solution. From the database schema to the UI, our teams own the full stack and deliver software that ships on time and scales with the business.
Capabilities
Six capability areas. One delivery team
Whether you are starting from a spec or stepping in for a stalled tape-out, PQ Angels has the engineering depth to take ownership.
Our capabilities span the entire VLSI flow.
Custom Application Development
Tailored web and desktop applications built around your workflow. We do not start with a template. We start with what your users actually need to do, then design around that.
- Web application development on modern frameworks
- Cross-platform desktop applications
- Progressive web apps for browser and offline use
- Internal tools and admin dashboards
- UX research, design, and front-end engineering
Enterprise Software Development
Functional verification, simulation, and validation that closes coverage with discipline. Our verification engineers build environments that catch the bugs that escape lower-effort teams.
- ERP, CRM, and operational system development
- Workflow automation and process digitization
- Identity and access management integration
- Multi-tenant architectures
- Compliance and audit-ready logging
Full-Stack Development
Front-end, back-end, database, and API expertise under one team. We deliver complete products, not fragments that someone else has to glue together.
- Front-end: React, Next.js, Vue, Angular
- Back-end: Node.js, Python, Java, .NET, Go
- Databases: PostgreSQL, MySQL, MongoDB, Redis, time-series stores
- REST and GraphQL API design
- Microservices and modular monolith architectures
Cloud & API Integration
Seamless third-party and cloud ecosystem integration. We build the connectors and orchestration layers that make your stack talk to itself.
- AWS, Azure, and Google Cloud architecture
- Serverless and event-driven systems
- Third-party SaaS integration
- Payment, identity, communication, and analytics platforms
- API gateway and event bus implementation
Software Testing & Quality Assurance
Functional, performance, and security testing built into the delivery pipeline. We do not treat QA as a phase at the end. We treat it as a discipline that runs alongside every commit.
- Manual and exploratory testing
- Automated functional testing
- Performance and load testing
- Security testing including SAST, DAST, and penetration testing
- Test automation framework development
Maintenance & Support
Continuous enhancement and long-term support. Most software costs more in the five years after launch than in the year of launch. We help clients manage that cost intelligently.
- L2 and L3 application support
- Bug fixing and patch management
- Feature enhancements and roadmap delivery
- Performance optimization and tech debt reduction
- Migration and modernization of legacy systems
How we engage
A flow built for tape-out predictability
Discovery
We start with a working session, not a sales call. We come away with a clear picture of the problem, the constraints, and the success criteria.
Proposal and roadmap
You get a scoped proposal with effort estimates, tech choices, and risks called out. No hidden assumptions.
Iterative delivery
Two-week sprints, working software at the end of each one, and a single point of contact who actually knows the code.
Launch and stabilization
Production deployment, post-launch monitoring, and a hand-off plan if you are taking the system in-house.
Ongoing partnership
Managed service contracts, retainer engagements, or sprint-on-demand. Your choice.

FAQs
Common questions
Can you take over a software project that another vendor started?
Yes. We start with a code review and a delivery audit, then propose a take-over plan. We have done this for clients on legacy stacks and modern ones.
Do you offer fixed-price contracts?
For well-scoped projects, yes. For evolving scope, time and material works better and protects both sides.
Who owns the code?
You do. All deliverables, source code, and documentation are yours under the engagement contract.
Do you build mobile apps?
Yes, on React Native and Flutter for cross-platform, and native for cases where performance or platform features demand it.
Can you work to our security and compliance requirements?
es. We have delivered for clients in regulated sectors and adapt our SDLC to ISO 27001, SOC 2, HIPAA, and similar frameworks as required.
Have a software product to build, modernize, or scale?
Send us a brief. We will respond with a scoping call and a proposal within five working days.
