Node.js Backend Developer + Full Stack Developer for Architecture Consultation
Second engagement after they ran the first scoping pass on the same product. We came back for a Node.js Backend Developer view on the server side - API design, queues, idempotency, the conversion reconciliation flow. Their PDM was a Clear Communicator across a written process, Detail Oriented where it counted on the schema and tenant_id choices we'd have paid for in a v2 migration. When we asked them to re-validate the hosting plan against GDPR, they were Solution Oriented and came back with a recommendation, not a list of options. Committed to Quality throughout, Accountable for Outcomes on a same-day pass through the integration risk section. We'll run the build through them.

Looking for expert nodejs developers
the collaboration with ABZ is really exceptional, we have rarely seen a team be so well organized and processed, the end result is the smoothest IT contracting experience we've ever had.
some rules can seem like a pita at the beginning (strict NO calls policy, NO front dev before a figma is provided, etc..), but in reality, they are what make the experience so good, everything is written and well documented (they ask a lot of clarifying questions before starting to code) which resulted in about a 90% reduction in bugs compared to our previous contractor; and the rule about figma results in pixel-perfect integrations everytime, what they deliver is exactly what we expected because it's exactly what was in the figma.. absolutely brilliant.

Developer needed to create a website for checking mobile phones
It's been a great pleasure working with this agency from start to finish. It was our first time outsourcing a web development project and we've learned so much about the strategic process involved - it's very well structured, easy to follow, and progresses very quickly once they get a decent understanding of the requirements. The quality of the final product is outstanding, but it's also evident throughout the planning of the project. We've already started another project with them, and plan to give them any others that we decide to build.

Create custom CRM for medical practice
Project got delayed because of Covid and lack of available resources, and communication was not ideal because of ABZ policy, which led to some frustration.
However, skills and quality of work are undeniable so good experience overall.

Job Success
Kiev, Ukraine - 10:15 am local time
As CEO I scope and own every Node.js Backend Developer engagement we sign. I study the brief, run discovery with founders, match the right engineers and stay accountable for delivery. My team owns the code - I never touch it. So when a brief lands for a Backend Engineer, an API Developer or a full stack software engineer, I scope it and the team builds it.
Why hire my team:
- 20+ years of Node.js Backend Developer, Full Stack Developer and SaaS Developer delivery
- 200+ Node.js Backend Developer and SaaS Developer projects shipped
- Long-term clients on retainers (3 - 10+ years)
Our Node.js Backend Developer team designs services, REST and GraphQL APIs, queues and event pipelines that hold up under real production load. A NestJS Developer on the team treats Node as a serious production runtime and owns the heavy backend modules. Typical engagements: multi-tenant SaaS APIs, real-time platforms, billing flows, data pipelines, AI-backed services. Stack: Node.js, NestJS, ExpressJS, TypeScript, PostgreSQL, Redis, Elasticsearch, AWS, GCP, Docker, Kubernetes.
Our Full Stack Developer team owns systems end-to-end - one team handling Node.js services, React frontends, data models and infra. A React Node pairing is our default shape - a React Node frontend on a NestJS Developer backend, with a nextjs developer on SEO-critical pages. We replace fragmented setups where a website developer, web developer and front end specialist were stitched together. Adjacent angles I present daily: full stack developer saas for B2B platforms, python full stack developer pairings for data and AI, full stack developer ai integrations, full stack developer react teams for SaaS dashboards, full stack developer shopify extensions, full stack web developer rebuilds of legacy SPAs, full stack ai saas developer engagements where LLM features must ship at production standard.
Our SaaS Developer team helps founders ship multi-tenant SaaS and B2B platforms. A SaaS Developer engagement covers auth and RBAC, Stripe billing, observability, anti-abuse and event tracking the saas marketing team can use. The team has shipped a webflow developer saas pairing, a b2b saas booking system developer engagement, a ui ux designer saas pipeline, a saas explainer video flow in onboarding and a saas sales console wired into the backend.
On the API side a dedicated API Developer track owns contracts and versioning. A REST API Developer designs the REST API Developer surface - resources, pagination, idempotency, webhooks - and the API Developer keeps SDKs and docs honest. A Backend Engineer owns the data layer; a second Backend Engineer covers queues and workers so the API never blocks on jobs.
Cross-language coverage. A python developer track owns scraping, ETL and AI workflows. python nodejs migrations land here when teams consolidate dual stacks. flutter node.js and vue.js node.js setups join the core when mobile or admin SPAs need a reactive layer. A react developer pairing handles SaaS dashboards on the API. A wordpress developer or shopify developer hand-off covers CMS migrations. A mobile app developer pairing extends the SaaS into iOS and Android.
Clients hire me when they need:
- a Node.js Backend Developer team that owns architecture, APIs and scaling
- a back end developer node.js bench for high-traffic SaaS
- a Full Stack Developer team replacing 3 - 5 contractors with one coherent system
- a SaaS Developer team fluent in multi-tenancy, auth, billing and RBAC
- an API Developer and Backend Engineer pair for a clean, versioned REST API Developer surface
- a full stack software developer practice with CEO-level discipline on roadmaps
- a website developer hand-off backed by the team
Recent work my team shipped:
- Cybersecurity SaaS. Node.js, NestJS, PostgreSQL, Redis on GCP + Kubernetes. 170M+ req/week, 500 RPS peaks, 1M+ MAU.
- Device Verification SaaS. Single backend powering web, Telegram bot and Developer API. 4K+ DAU, 1M+ checks, 80%+ via API.
- Clinic Enterprise platform. React, Next.js, Laravel, Node.js, Redis, AWS. REST API, queues, RBAC, 1C and lab integrations. MVP in 4 months for 500 patients/day, 500K records.
- E-commerce Data Pipeline SaaS. 50M+ products, per-partner parsers, dedup. Cloud cost cut ~9x at sub-second search across 300 - 500K DAU.
- Multi-currency Voting SaaS. Wallets, Stripe top-ups, real-time vote locking over WebSockets. 2M+ users in 10 countries, $2.5M+ revenue.
Reliable SaaS comes from deliberate design - that's what my Node.js Backend Developer, Full Stack Developer and SaaS Developer team focuses on.
Need a Node.js Backend Developer team, a Full Stack Developer team or a SaaS Developer partner that delivers on time and stays long-term - let's talk.
