Selected work
Every engagement ends with working software in production — not a GitHub repo no one opens.
10× scale — from 200 to 2,000+ active clients
SaaS Platform
Built a fullstack SaaS application from zero — React frontend, Node.js API, PostgreSQL, deployed on AWS. Replaced a manual spreadsheet process that was breaking at 200 clients. The new platform now handles 2,000+ active accounts.
6-week launch — from spec to App Store
Mobile + API
Designed and built a cross-platform mobile app with a custom REST API layer connecting to Plaid, Stripe, and three legacy banking systems. Launched in 6 weeks. Zero critical security incidents in 18 months post-launch.
40 min → 3 min build — ops efficiency doubled
Platform Migration
Migrated a brittle Python 2 monolith to a modern microservices architecture with zero downtime. Reduced build times from 40 minutes to under 3 minutes. The ops team cut their manual triage work in half within the first month.
How it works
No disappearing acts, no vague timelines, no "we'll figure it out" handwaves. Here is exactly what working together looks like.
Discovery
1–2 days / kickoff call + async briefMost projects fail before they start — the wrong problem gets solved. The first week is a deep-dive: your business context, technical constraints, what success looks like in three months. We align on scope, not just features.
Architecture
3–5 days / architecture doc + tech specA clean architecture prevents 80% of technical debt. Before any code, we define the data model, API contracts, infrastructure requirements, and deployment strategy. Decisions made here compound — good or bad — for years.
Build
2–8 weeks / iterative sprintsWeekly working builds, not monthly PowerPoint updates. Every feature ships to a staging environment you can touch. You know exactly what was built, what's next, and whether the timeline is holding. No surprises at handoff.
Launch
Final week / deploy + handoff docsDeployment pipelines, monitoring, error tracking, database backups, security headers, and performance benchmarks — all configured before the first user touches the product. You get the repo, the infra access, and the runbook.
About
Most developer portfolios speak in tech stacks. Veltex speaks in outcomes.
Veltex is the engineering practice of a senior fullstack developer with experience building production systems across fintech, SaaS, and operations tooling. Not a team of 50 with a sales layer. One person who writes the code, reviews the architecture, and cares about what ships.
Founders and product managers hire Veltex when they are tired of agencies that over-promise and freelancers who disappear. The expectation is simple: working software, on time, explained in plain English.
Core capabilities
What this is not
A dev shop that vanishes after launch. An offshore team running on 12-hour delays. A template with your logo on it. Veltex builds systems that the team you hire next can actually work with.
