Core Methodology
Specification-First Engineering
Most teams prompt AI and hope for the best. We use a structured 6-phase methodology where specifications become executable artifacts that AI agents build from - not documents that gather dust.
The result: significantly faster delivery, fewer escaped defects, and code that matches intent on the first pass.
Our white paper covers the full methodology, recommended toolchain, 7 lifecycle phases with AI augmentation, and the tradeoffs we've learned shipping with this approach.

What does a product engineering engagement look like? +
Most engagements start with a 2-week discovery sprint where we map your technical landscape, define architecture, and identify risks. From there we move to a foundation sprint (2-4 weeks) to set up infrastructure, CI/CD, and core functionality - then into iterative 2-week delivery sprints with weekly demos and continuous testing.
How fast can you ramp up a team? +
We deploy full product teams in 4-6 weeks. A typical team includes 2-4 engineers, a QA specialist, and a technical lead. For urgent projects we can start with a smaller pod in 2 weeks and scale up as requirements stabilize.
What tech stack do you use for product development? +
Our core stack includes React, Next.js, Node.js, Python, .NET, and Java for application development. We deploy on AWS, Azure, and GCP using Kubernetes, Terraform, and Docker. For AI/ML we use PyTorch, LangChain, and OpenAI. We match the stack to your requirements - not the other way around.
How do you integrate AI into the development process? +
Every team uses AI-assisted development tools for code generation, automated code review, test generation, and architecture analysis. This means faster delivery without sacrificing quality. We also build AI features into the products themselves - RAG pipelines, ML models, GenAI integration - when the use case calls for it.
What is your approach to quality assurance? +
QA is embedded from day one, not bolted on at the end. We run automated test suites on every commit (unit, integration, E2E), AI-assisted test generation for edge cases, performance testing with k6, and security scanning with OWASP ZAP. Every sprint includes a stabilization phase before deployment.
How do you handle scaling from MVP to production? +
We architect for scale from the start - containerized deployments, auto-scaling, multi-region capability - even during MVP. When traffic grows, we add performance monitoring (Prometheus, Grafana), implement caching layers, optimize database queries, and scale infrastructure horizontally. No re-architecture needed.
What industries do you serve? +
We serve enterprise clients across FinTech, SaaS, Intelligent Transportation Systems (ITS), manufacturing, and retail. Our engineers have deep domain expertise in regulated industries where compliance, security, and reliability are non-negotiable.
How does the Pilot/PoC model work? +
A Pilot/PoC engagement runs 4-8 weeks at $15-25K. We take a single, well-defined use case and deliver a working prototype - not a slide deck. This lets you evaluate our engineering quality, communication style, and domain fit before committing to a longer engagement.
Does Specification-First Engineering slow down delivery? +
For small bug fixes and trivial changes - yes, the overhead isn't worth it. But for features and greenfield projects, specification-first workflows actually accelerate delivery because AI agents execute from precise specifications instead of ambiguous prompts. We right-size the process: full spec-first for substantial work, lightweight AI-assisted coding for quick fixes.
How do you ensure AI-generated code is production-ready? +
AI code goes through the same validation as human-written code - automated security scanning, architecture compliance checks, performance testing, and human review. Many developers report extra debugging during initial AI adoption, so we invest in 5-pillar validation: security, testing, architecture, performance, and compliance.
How do you prevent specs from falling out of sync with code? +
We treat specifications as living artifacts, not static documents. Hooks and agents automatically flag when code diverges from specs. During code review, AI validates changes against the original spec. Specs are updated as part of the development workflow, not as an afterthought.
How do junior developers grow when AI handles 'easy work'? +
We use AI as a teaching tool, not a replacement for learning. Junior developers pair with AI to understand codebases faster, but they're still responsible for understanding the 'why' behind changes. Code review sessions, architecture discussions, and spec writing develop fundamentals that AI can't replace.
