Mr. RJ Macasaet

They were able to maintain team performance across a relatively large team, provide additional resources when required, and work collaboratively with us on matters such as gap time, discount proposals, and improvements to the working process. Their flexibility and consistent management support contributed positively to the overall partnership.

During our collaboration, Mr. Thanh and his company, Saigon Technology, have consistently demonstrated world-class leadership and execution in complex fintech projects.

Why US Companies Choose Saigon Technology
When US teams hire an external engineering partner, the usual fear is a junior-heavy bench that ships fast and breaks later. Saigon Technology's 400+ software developers are led by senior engineers who own architecture and code review, and one senior engineer + AI ≈ the output of three juniors. You pay for fewer people and fewer do-overs, so the total bill drops even when the hourly rate doesn't.
At a published senior-led rate of $22-$46 per hour, the budget still covers the hardening, testing, and versioning that premium onshore rates usually squeeze out.
Many vendors now list AI; far fewer run it in production. At Saigon Technology, Phong Le, our AI Tech Lead, and a senior bench of Solution Architects and Tech Leads back every team, so AI-accelerated workflows run inside delivery, not beside it. Behind them sit 50+ AI projects delivered by 30+ AI engineers across healthcare, fintech, and logistics, so AI ships as production-ready systems, not demos.
Before you commit budget, you can inspect working AI demos, such as fracture detection, semantic search, and OCR, in our Research Labs.
Architecture advice from day one, including when not to build. Domain teams in healthcare, fintech, logistics, and business software scope AI-accelerated MVPs and PoCs, so you validate with real users before funding the full build.
A US healthcare or fintech build can fail an audit long before it fails a test. Saigon Technology works under ISO 9001 and ISO 27001, certified by BSI (UK), with NDAs, role-based access, and client-owned repositories on every engagement. Where the workload needs it, we structure delivery to meet HIPAA and PCI-DSS requirements, support HL7 interoperability and GDPR, and keep the audit trails your compliance team will ask for. Our US case studies, from a HIPAA-compliant telemedicine platform to a lending system, show that work in production.
Scaling an external team often means renegotiating, re-onboarding, and losing the people who built version one. Saigon Technology has delivered 85+ dedicated teams and transferred 40+ developers to clients through BOT, from three development centers that let you ramp capacity up or down. Choose ODC, Dedicated Team, Staff Augmentation, Fixed-Price, or BOT, with no vendor lock-in. Retention keeps that scale stable: #10 (Medium) in Southeast Asia Best Workplaces™ in Technology 2026 by Great Place To Work, and #52 on Fortune's 2025 Best Companies to Work For™ Southeast Asia. The engineers who designed your system are still here when it has to change.
14+ years · 400+ developers · 850+ projects · 350+ clients · 4.8★ on Clutch · 3 development centers, backed by real case studies.
Saigon Technology's Reston, Virginia team works US business hours. Delivery teams give you 10-12 hours of daily overlap with East and West Coast time zones, and on request, our developers in Vietnam work your US business hours, in fluent English. Decisions land the same day, not the next morning.

Our Insights
FAQs
A software development company in the USA designs, builds, tests, and maintains software for businesses operating in or serving the American market, including custom applications, web and mobile apps, SaaS platforms, and AI solutions. Saigon Technology delivers full-lifecycle development from our Reston, Virginia office.
Off-the-shelf tools fit the average business. Custom software fits yours. Here is what US teams gain by building:
- Lower total cost of ownership. Replace stacked per-seat SaaS fees with software you own outright.
- Compliance fit by design. HIPAA and PCI-DSS requirements met where your workload needs them, with GDPR support built in, not bolted on.
- Faster time-to-market. A working MVP in weeks, then releases every few weeks.
- Architecture that scales. Cloud-native from day one, deployed to the same AWS regions that power Northern Virginia.
- Full IP ownership. Your source code and your contracts, protected by NDAs.
- AI-native productivity. Senior engineers plus AI tooling help you build faster, scale leaner, and work smarter in the AI era.
Our US office is Saigon Technology USA Inc., 12110 Sunset Hills Rd, Ste 600, Reston, VA 20190. From Virginia we serve clients nationwide, supported by three ISO-certified engineering centers.
You get the same, or higher, engineering quality with a smaller team. Senior engineers paired with AI ship the same scope with fewer people and less rework, so the total bill drops even when the hourly rate doesn't. As a software development company in Virginia, we pair that with fluent English and US time-zone overlap, keeping collaboration as smooth as an onshore engagement.
Saigon Technology projects start from $10,000, the minimum project size listed on our Clutch profile, and our published senior-led rate is $22–$46 per hour. For reference, the median US software developer wage was $135,980 in May 2025 (US Bureau of Labor Statistics). A salary is not a billing rate, so treat it as a reference point rather than a like-for-like comparison.
Beyond cost, the difference shows up in speed and risk. Standing up an in-house team means weeks to months of hiring before you see a first approved CV, while Saigon Technology can put a qualified candidate in front of you within days. And where an in-house hire offers no built-in safety net, Saigon Technology backs the engagement with a 2-week risk-free trial.
Predictable delivery is the difference between a vendor and a partner. Our project management practices are built for fact-based decision-making and full transparency:
- Methodologies: Scrum with 2-3 week sprints, Kanban for support and evolution, and Agile development end to end.
- Cost estimation: transparent, feature-level estimates with no surprise billing.
- Risk management and change management: structured processes to catch issues early and absorb scope changes.
- Quality management system: a shift-left approach to QA, code reviews, test automation tools, and a clear "definition of done."
- Success measurement: KPIs, weekly report examples, and joint reviews to keep cooperation healthy.
Yes. We structure engagements to meet HIPAA requirements for healthcare and PCI-DSS and KYC/AML requirements for fintech, with HL7 interoperability support where the workload needs it. All work runs under an ISO 27001-certified security management system with audit trails and role-based access.
- Startups: Staff Augmentation or Fixed-Price to validate fast and control budget.
- Scale-ups: a Dedicated Team for an evolving roadmap.
- Enterprises: an ODC or BOT model to own, or eventually absorb, a full team.
After a discovery call and scope review, we share a shortlist of matched engineer profiles within 1–2 working days of your role brief and can stand up a team in about 5 days. A 2-week risk-free trial lets you validate fit before committing.
Yes. We operate an ISO 27001-certified security management system, sign NDAs, and use role-based access with client-owned repositories. You retain full ownership of code and IP, and we support GDPR and HIPAA compliance for regulated industries.
