Three anonymized backend engagements where architectural decisions produced measurable outcomes. Baselines client-reported, metrics independently verified.
Monolithic Rails backend hit p99 latency of 4.2 seconds during peak betting windows. 14 production incidents in the last quarter. Engineering team afraid to deploy on Sunday mornings.
Selective extraction to Go services for hot paths (odds, bet placement, settlement). p99 latency dropped to 180ms. Zero peak-window incidents in 4 months post-cutover. Deployment frequency went from weekly to multiple times per day.
We extracted three services that owned 85% of the request volume and left the rest as a Rails monolith. Cutover used a request shadowing pattern — every request hit both stacks for 2 weeks before the new stack became authoritative.
Synchronous request chains across 7 microservices. One slow downstream caused cascading timeouts. Reconciliation reports lagged 18 hours behind real-time.
Kafka event bus with idempotent consumers and outbox pattern. Reconciliation lag down to 90 seconds. Cascading failures eliminated. Each service can be deployed independently.
The outbox pattern is the key — every state change writes to a local ledger table inside the same database transaction, then a separate process publishes to Kafka. No dual-write inconsistency, no lost events on crash.
3 different backend APIs powering web, mobile and partner integrations. Drift between them caused 1-2 production bugs per week. Schema changes required coordinated releases across 3 teams.
Single GraphQL API with persisted queries and federated subgraphs. Bug rate dropped 70%. Schema changes ship in one PR. Mobile and web teams iterate independently behind a stable contract.
GraphQL federation let us ship the consolidation incrementally — each subgraph migrated one bounded context at a time, with the gateway routing between old REST and new GraphQL during the transition. No big-bang cutover.
Client names anonymized under NDA. Full case studies at /cases/.
We decline roughly 30% of RFPs we receive. Forcing a bad fit costs both sides 3-6 months and damages outcomes. Here is how we think about scope:
Custom backend makes sense when you need complex business logic, integration with proprietary systems, regulatory data residency, real-time scale or unit economics that BaaS pricing breaks. Otherwise, Backend-as-a-Service platforms (Supabase, Firebase, Hasura, AWS Amplify) ship faster and operate cheaper. We have built MVPs on Supabase and migrated to custom only after the platform hit a real wall.
Engagement model, pricing and case studies for software projects including the backend track.
Observations distilled from 48 back-end engagements delivered between 2019 and 2026 across FinTech, logistics, healthcare and SaaS.
Teams of 4 to 8 engineers reach DORA "High" performance within 6 months when we introduce trunk-based flow and contract tests on week one.
The single highest-impact intervention in 70 percent of rescues was splitting one shared relational database into bounded contexts with clear write ownership.
Services with structured logging plus tracing from day one had 3.1x lower MTTR than services that bolted observability on after launch.
Rewrite projects succeed when we preserve the legacy as a source of truth for 90 days of dual-run; bypassing that step correlated with 4 of 6 rollbacks in our records.
A logistics customer migrated from a PHP monolith to a Go service fleet in 2024. Load tests looked clean but the first production week logged 312 duplicate shipments on order retry bursts. Root cause: three services accepted POST without idempotency keys and the upstream queue retried on any 5xx. We shipped a cross-cutting middleware that derived idempotency keys from payload hashes and persisted them in Redis with 24-hour TTL, then re-ran the retry playbook. Duplicate rate dropped to zero within 48 hours and never came back. The lesson we standardised: no back-end service enters production without an idempotency contract on every state-changing endpoint[5].

Use Supabase or Firebase for CRUD MVPs, internal tools, prototypes and apps where the data model is generic. Build custom when you need complex business logic, regulated data residency, real-time scale, custom unit economics or integration with systems that BaaS does not cover.
Pharos has built MVPs on Supabase and migrated to custom only after the platform hit a real wall - do not migrate prematurely.
Defaults: Node.js or Python (FastAPI / Django) for general-purpose APIs and integration-heavy work; Go for high-throughput services and infrastructure tooling; Java/Spring or Elixir/Phoenix for high-concurrency low-latency systems; Rust where memory safety and predictable latency matter most. The right choice depends on your team skills, hiring market and existing infrastructure - we will recommend a different stack if your team is already strong in something else.
REST for public APIs, third-party integrations and simple service-to-service. GraphQL when multiple clients (web, mobile, partner) need flexible projections of the same data - federation lets multiple teams own subgraphs.
gRPC for internal service-to-service when latency and contract enforcement matter. Most Pharos backends use REST for the public surface and gRPC or events between internal services.
API MVP 6-10 weeks: 2 weeks discovery and data model, 4-6 weeks build with integration tests in CI, 1-2 weeks production hardening (monitoring, alerting, runbooks). Production backend with full integration suite 3-8 months.
Migrations and rewrites typically run 6-12 months including parallel-run validation and traffic cutover.
Discovery includes a load model (peak QPS, p50/p99 latency targets, data growth) tied to a load test harness that runs in CI on critical paths. We measure before optimizing - most performance problems are wrong queries and missing indexes, not language or framework choice.
When we do scale out, we prefer horizontal scaling on stateless services + careful database partitioning over premature microservices.
Yes, when they fit. Our default for new projects is a modular monolith with clear bounded contexts and a clean public API per module.
We split into services when one of three things happens: independent scaling needs, independent deployment needs across teams, or a clear bounded context that benefits from a different runtime. We do not recommend microservices for teams under 10 engineers - the operational tax outweighs the benefits.
Structured logging (JSON), distributed traces (OpenTelemetry → Tempo / Honeycomb / Datadog), metrics (Prometheus), and SLO dashboards on the critical paths. Every request carries a trace ID surfaced in logs and error reports.
Critical alerts page on-call via PagerDuty or OpsGenie. Runbooks live next to the alerts so the on-call engineer has the fix steps in the same place as the alarm.
Yes. Common patterns: strangler-fig (extract services from a monolith one bounded context at a time with a routing layer), parallel-run cutover (new and old backend serve the same traffic for a validation window), and behind-the-flag rewrites (new code path enabled for 1% of traffic, ramped to 100% on validation).
We never recommend big-bang rewrites on systems that are working - too risky.
We decline CRUD MVPs that should ship on Supabase, microservice splits for small teams, backend rewrites without a measured production problem, and Zapier-glue work dressed up as a backend. Strongest fit: high-throughput systems, regulated data, complex business logic, multi-tenant SaaS, real-time pipelines, event-driven architectures.
