How do you handle scope changes mid-project?

Every change gets an estimate before it enters a sprint. You approve or defer it. We never silently absorb scope and then surprise you with a timeline slip.

What if we want to take it in-house later?

That's a normal outcome and we plan for it. Documentation, tests and architecture decisions are written for a future engineer who has never met us. We also run paid handover periods.

Can you work with our existing systems?

Yes — most of our work involves integrating with systems already in place. We audit what exists during discovery and design around it rather than demanding a rewrite.

Custom Software Development

Off-the-shelf software forces your business to work the way the vendor imagined. We build the system your operation actually needs — designed around your domain, sized to your real load, and handed over with the source code and the architecture decisions written down.

Problems

You're probably here because of one of these.

If more than one sounds familiar, that's normal — they usually share a root cause.

Your process lives in spreadsheets

Critical operations run on shared workbooks with no audit trail, no validation, and one person who understands the formulas. It works until it doesn't.

You're paying to be constrained

Per-seat licensing for a platform that can't model your workflow, so your team maintains a shadow process alongside it.

Nothing talks to anything

Your CRM, accounting, inventory and support tools each hold a piece of the truth, and reconciling them is somebody's full-time job.

The last developer left

An internal tool nobody can safely change, with no tests, no documentation, and no one who remembers why it works.

Approach

How the work actually runs.

From first conversation to running in production. Typical end-to-end duration for custom software development is 12–24 weeks.

01
Discovery
1–2 weeks
We map the problem before proposing a solution. Stakeholder interviews, constraint analysis, and a written scope you actually own.
- Stakeholder interviews and workflow mapping
- Technical constraints and integration audit
- Written scope, risks and success metrics
- Fixed-price proposal with a delivery plan
02
Architecture & design
2–3 weeks
System design and interface design happen together, so the thing we draw is the thing we can actually build.
- Domain model and data architecture
- Service boundaries and integration contracts
- Interface design for every core workflow
- Authorization model and audit-trail design
03
Build
8–16 weeks
Two-week iterations against a shared board. You get a working deployed environment from week one and a demo every sprint.
- Core domain logic with automated test coverage
- Admin tooling and role-based access control
- Third-party integrations with retry and reconciliation
- Data migration from existing systems, run and verified
04
Hardening
1–2 weeks
Automated test coverage, load testing, accessibility audit and a security review before anything touches production.
- Unit, integration and end-to-end test suites
- Load and performance profiling under realistic traffic
- WCAG 2.2 AA accessibility audit and remediation
- Dependency, authentication and access-control review
05
Launch
1 week
Staged rollout with monitoring in place before traffic arrives. Rollback is tested, not assumed.
- Infrastructure as code, reproducible across environments
- Phased cutover with parallel-run against the old system
- Team training sessions and written runbooks
- Full source code and infrastructure handover
06
Operate
Ongoing
We stay on. Response-time SLAs, proactive dependency upgrades, and a roadmap review every quarter.
- Uptime, error and performance monitoring with alerting
- Defined severity levels and response-time commitments
- Scheduled dependency and security patching
- Quarterly roadmap and architecture review

Included

What you get, spelled out.

Every item here is part of the engagement, not an upsell discovered halfway through.

Source code ownership

You own the repository, the infrastructure and the IP. No lock-in, no licensing, no hostage situation.

Domain-driven data model

A schema that matches how your business thinks, not how a generic CRM does — with module boundaries that let services be extracted later without a rewrite.

Role-based access control

Granular permissions with a complete audit trail of who changed what and when.

Integration layer

Reliable connections to your accounting, CRM and logistics tools — idempotent, retried with backoff, and reconciled so a failed webhook never silently drops a record.

Admin dashboard

Operational tooling so your team can manage the system without calling us.

Automated test suite

Unit, integration and end-to-end coverage that lets any future engineer change the system with confidence.

Architecture decision records

Every significant choice written down with what we rejected and why, alongside runbooks and onboarding docs. Not auto-generated filler.

Data migration

Your history moves with you, validated record by record before cutover.

Stack

What we typically build this with.

A default, not a rule. If your team already runs something else and it fits the requirement, we work in your stack.

TypeScript

Types across the whole stack. Most integration bugs stop being possible.

Node.js

One language across client and server. Shared validation, shared types, one hiring profile.

NestJS

Opinionated module boundaries and dependency injection — what keeps a service from becoming a ball of mud at scale.

PostgreSQL

Our default. Transactional integrity, JSON, full-text search and row-level security in one engine.

Next.js

Server rendering, streaming and edge delivery without hand-rolling the infrastructure.

Docker

The same image in dev, CI and production. 'Works on my machine' ends here.

Nginx

Reverse proxy, TLS termination and load balancing. What makes a self-hosted deployment behave like a managed one.

AWS

Widest service coverage and the compliance posture enterprises expect.

Self-hosted

Your own servers, your own datacentre, or a VPS you control. Same containers, same pipeline, no cloud lock-in.

Redis

Caching, rate limiting, queues and sessions. Boring in the best way.

Why Devsock

The difference is in how the work is run.

Ten dimensions where engagements usually go wrong, and what we do instead. Every claim in the right-hand column is something you can verify in the first two weeks.

DimensionTypical agencyDevsock

Estimates
TypicalAn hourly rate and a range that grows once work starts.
DevsockFixed scope and fixed price after a paid discovery. Changes are quoted before they enter a sprint.
Communication
TypicalA weekly status email written by an account manager.
DevsockDirect access to the engineers building it, a shared board you can read any time, and a demo every second week.
Code ownership
TypicalDelivered at the end, sometimes with a proprietary framework attached.
DevsockYour repository, your cloud account, from commit one. No proprietary layer, no licensing.
Testing
TypicalManual clicking before launch, if the timeline allows.
DevsockAutomated suites in CI, load testing at projected peak, and a WCAG 2.2 AA audit before release.
Architecture
TypicalWhatever the available developer knows best.
DevsockA written architecture decision record explaining what we chose, what we rejected, and why.
Security
TypicalAddressed if the client raises it.
DevsockDependency scanning in CI, least-privilege access, secrets management and a pre-launch review as standard.
Accessibility
TypicalOut of scope unless legally forced.
DevsockWCAG 2.2 AA designed in and audited. Keyboard and screen-reader tested, not assumed.
Handover
TypicalA zip file and a phone number that stops answering.
DevsockDocumented architecture, runbooks, and a paid handover period so your team can genuinely take over.
After launch
TypicalA new quote for every bug.
DevsockDefect fixes covered for 90 days. Support retainers carry response-time SLAs in the contract.
Saying no
TypicalEvery request becomes a line item.
DevsockWe'll tell you when a feature isn't worth building, or when the answer isn't software at all.

Multi-tenant SaaS platform and driver apps for dumpster rental operators

Challenge

Dumpster rental operators run bookings, fleet position, driver assignments and invoicing across spreadsheets, whiteboards and phone calls. Nobody knows where a container actually is, proof of service arrives days after the job, and billing gets reconstructed from memory at month end.

Solution

A multi-tenant SaaS platform with self-serve signup, subscription billing and tiered plans, paired with native driver apps on iOS and Android. Operators get real-time container status, driver scheduling with route optimisation, customer and contract management, and automated invoicing. Drivers receive job assignments and upload proof of service from the field.

What shipped

Native driver apps published to both the App Store and Google Play
Multi-tenant architecture with per-operator data isolation
Self-serve onboarding with a 15-day trial and three subscription tiers
Real-time inventory and container status tracking
Driver scheduling with route optimisation
Automated invoicing and payment processing

Corporate platform for an independent renewable-energy consultancy

Challenge

An independent monitoring and evaluation consultancy for renewable energy projects needed to establish credibility with government, industrial and hospital buyers — a sector where procurement turns on verifiable regulatory standing and a demonstrable track record, not on marketing copy.

Solution

A structured corporate platform built around proof rather than persuasion: service definitions for independent oversight and technical training, a credentials section surfacing regulatory compliance across SECP, FBR, PRA and PEC, team profiles establishing sector experience, and a documented track record of verified installations. Enquiries route directly to the consultancy team.

What shipped

Structured service architecture across oversight and training lines
Regulatory credentials surfaced as the primary trust signal
Track record documented across government, industrial and public-health installations
Team credibility profiles with sector experience
Enquiry capture routed to the consultancy team
Server-rendered and fully indexable

Training platform with multi-country scheduling and certificate verification

Challenge

A QHSE training provider delivering internationally accredited certifications across Saudi Arabia, the UAE and Pakistan needed to publish a constantly moving multi-city schedule, take registrations online, and let employers independently verify that a certificate is genuine — the last of which is what makes an accreditation worth anything.

Solution

A training platform combining a published course schedule across multiple countries with online registration, a separate corporate training enquiry path, and a public certificate verification tool employers can use to authenticate credentials. Accreditation bodies and trainer profiles are presented as structured, checkable content rather than a logo wall.

What shipped

Public certificate verification for employers
Multi-country training schedule with online registration
Separate paths for open-enrolment and corporate training
Course catalogue spanning ISO, OSHA, IOSH, NVQ and Lean Six Sigma
Accreditation bodies and trainer credentials as structured content
Server-rendered and fully indexable
