Software engineering · Production systems
We help startups build stable systems.
Most systems look fine until they don't. We work with founders and product teams who can't afford to find out the hard way — whether that's an AI prototype that needs a real security review before launch, a system that's getting slower every month, or something that simply needs to be built properly from the start.
Services
AI prototype assessment
High demandYour team — or an AI tool — built a working prototype. Before you invest in scaling it, or hand it to real users, you need to know what you actually have. We review the code, architecture, infrastructure and security, then give you a straight answer.
- — Security vulnerabilities and credential exposure
- — Architecture and scalability risks
- — Code quality and maintainability assessment
- — Written report: what to fix, what to rebuild, what's fine
- — Production-readiness estimate with effort and cost
Full-stack development
🛠️ End to endWe design, build and ship web applications for companies that need something built properly the first time. Architecture, implementation, infrastructure — handled. You focus on your business. No agency layers, no account managers in the middle.
- — Web applications and internal business tools
- — System architecture and data modeling
- — API design, integrations and third-party services
- — Deployment pipelines and production infrastructure
Production stabilization
🔥 RescueFor systems that are getting slower, harder to deploy, or increasingly fragile. We find what's actually wrong — not just the symptoms — and fix it without burning everything down and starting over.
- — Performance diagnosis and database optimization
- — Observability, monitoring and alerting setup
- — CI/CD and safe deployment processes
- — Architectural cleanup and technical debt reduction
Who we work with
Problems we solve
Scenario · AI prototype going to production
A founder used AI tools to build a working product quickly. It demos well. The plan is to start onboarding real users within weeks. Nobody has looked closely at the infrastructure, credential handling, or what happens when ten users hit it at once.
What a proper audit surfaces
JWT tokens being decoded but never verified against a secret. Anyone could forge a token, claim to be any user, and access their data.
Outcome: A week of focused review and a targeted fix plan. The startup launches on schedule, with no security incidents, no user trust damage, and no regulatory exposure. The alternative — discovering this after real users are in the system — is substantially more expensive and much harder to recover from.
Scenario · Performance diagnosis
A data-heavy application is running slow. The team suspects the language or framework choice — maybe it needs a full rewrite in something faster. A year of development is being planned. Budget is already mentally allocated.
What we often find instead
The bottleneck is between the application and the database — too many round trips, missing indexes, queries that load far more than they use. The language was never the problem.
Outcome: Two weeks of targeted fixes — query optimization, batching IO, selective caching — deliver a 50x performance improvement. The rewrite never needed to happen, no timeline slippage, no wasted budget. This kind of misdiagnosis is more common than most teams want to admit.
Why Appweaver
No agency overhead
Work is done by senior engineers, not handed down a chain. You get the expertise without the markup.
Operators, not advisors
The goal is a working system, not a report that sits in a folder. We measure success by outcomes.
Specialists when needed
Trusted senior engineers join specific phases when deep expertise matters — no outsourcing layers.
Production-first mindset
Every decision is made with real operational pressure in mind. We don't experiment on live systems.
How it works
Technical consultation
A focused conversation to understand your system, your situation and what needs to happen.
Scoped diagnostic
A fixed-price audit that maps the real risks, architecture gaps and a prioritized plan. You know exactly what you're dealing with before committing to anything larger.
Execution or handoff
We either do the work, or you take the report and run with it. Either way, you leave with a concrete action plan — not general advice.
Continued partnership
Ongoing fractional engineering, architectural oversight, or continued feature delivery — whatever form makes sense at each stage of your project.
Engagements start with a fixed-scope diagnostic — a low-risk entry point that gives you a concrete picture of your system's risks and next steps before any larger commitment is made.
