Development
Full-stack product work — features, APIs, dashboards, and integrations. Clean architecture, reviewed code, and delivery that respects your roadmap.
corebits.co · Dev & QA office
Core Bits is built for teams that need strong engineering and serious quality — shipping software that holds up in production.

About us
Core Bits is a Development and QA office — two disciplined teams working side by side so software is not only shipped, but proven before it reaches users.
Our developers own architecture, features, and integrations. Our QA engineers own test strategy, coverage, and release readiness. Together we reduce handoff gaps, catch defects early, and keep delivery honest from kickoff to go-live.
Whether you need a full product squad or dedicated Dev / QA capacity, we plug into your roadmap with clear communication and a shared definition of done.

Services
Focused services from our Development and QA teams — pick what you need, or run both under one delivery rhythm.
Full-stack product work — features, APIs, dashboards, and integrations. Clean architecture, reviewed code, and delivery that respects your roadmap.
Manual depth plus automation where it pays off. Test plans, regression, API checks, and release sign-off so builds leave the office ready for users.
Dev and QA as one office — shared sprint goals, early test involvement, and fewer handoff gaps between “done coding” and “safe to ship.”
Features, APIs, and product modules built to your backlog and acceptance criteria.
Manual, regression, and automation coverage with clear release readiness reports.
Embedded Dev or QA capacity that works inside your tools, sprints, and process.
Pre-ship checks, defect triage, and UAT support so go-live stays controlled.

Our teams
A closer look at what our Development and QA teams own — the skills they bring, the work they ship, and how they keep products moving from backlog to a stable release.
Team 01
Engineers who turn requirements into reliable product — architecture, code reviews, and delivery staying in sync. From greenfield builds to phased rebuilds, the team owns the full path: planning technical approach, writing maintainable code, integrating services, and handing off builds that QA can verify with confidence.
We work in short cycles with clear acceptance criteria, so stakeholders see progress early and scope stays honest — without sacrificing structure for speed.
Build · Integrate · Ship
End-to-end product modules — auth flows, billing hooks, notifications, and admin tooling — planned, built, and shipped inside clear sprint cycles with reviewable pull requests.
Stable services with documented contracts, validation, logging, and error handling. Designed so client apps and partners can integrate without guesswork or silent breakages.
Legacy screens and backends modernized into maintainable stacks. We migrate in phases so business delivery continues while technical debt comes down week by week.
Ops and admin tools that teams actually use — filters, exports, role-based access, and clear data views that cut support tickets and manual spreadsheet work.
Payment gateways, CRMs, email providers, and custom webhooks wired cleanly — with retries, idempotency, and monitoring so third-party failures don’t cascade.
Reusable UI layers, design tokens, and responsive layouts so new features land faster and stay visually consistent across the product.
Team 02
Testers who protect the release — coverage, clarity, and calm under deadline pressure. QA sits beside development from day one: reviewing requirements, writing test plans, and catching gaps before they become production incidents.
Manual depth meets automation where it matters. Every release gets a clear readiness call — what passed, what failed, and what risk remains — so shipping decisions stay informed, not hopeful.
Plan · Verify · Sign-off
Structured regression before every ship — critical paths, edge cases, and environment checks documented so production surprises drop and go/no-go calls stay clear.
High-value flows automated (login, checkout, core APIs) so teams move faster without skipping quality gates. Suites run in CI and flag breaks early.
Clear bug reports with steps, severity, environment, and expected vs actual. Tight loops with developers until issues are verified closed — not just marked done.
Endpoint validation, status codes, payloads, and auth scenarios covered so backend changes don’t silently break clients or partner integrations.
UI verified across major browsers and key device widths — layout, forms, and interactions checked so users don’t hit “works on my machine” failures.
We partner with stakeholders during UAT — test cases, walkthroughs, and issue logs — so business sign-off is informed, not rushed at the last hour.
How we work
01
Every feature earns its place. We clarify scope early so engineering time goes into what users and the business actually need.
02
Quality is a process, not a last-minute pass. Cases, automation, and sign-off sit beside development from kickoff onward.
03
Developers and QA stay aligned on acceptance criteria, risks, and release timing — so handoffs stay short and ownership stays clear.
FAQ
Short answers about how our Development and QA office works.
Core Bits is a Development and QA office — we build software and test it rigorously so products stay stable and production-ready.
Web apps, APIs, dashboards, and end-to-end product features. Clean architecture, modern stacks, and maintainable code are our focus.
Manual testing, regression suites, automation, API testing, bug tracking, and release readiness. Quality is part of the process from day one — not a bolt-on at the end.
Yes. You can take full delivery (Dev + QA), or dedicated development / dedicated QA augmentation — whichever fits your project.
Most engagements kick off within 1–2 weeks after a discovery call. Exact timing depends on scope and team availability.
