Manual Workflows Eat Hours
Your team spends hours each week on tasks software handles in minutes. Data entry, status updates, handoffs, the work that doesn't scale.
I build custom ERPs, Business Management Systems & internal tools for growing businesses.
Fullstack web development with clean, practical interfaces built with Ant Design. For the teams who need software that fits the way they actually work.

§ 02 / The Problem
The workarounds that got you here won't get you further.
Most teams don't need "more features". They need the friction removed.
025 apps that don't talk to each other
Disconnected Tools
Inventory in one system, purchasing in another, HR in a third. Reconciling them means manual exports, VLOOKUPs, and hope.
0320 clicks to pull 6-month-old data
Finding Records Is a Project
History lives in email threads, chat logs, and commented-out rows. Audits take days. Decisions wait on detective work.
04More people, same broken workflows
Hiring Doesn't Fix Process
Adding headcount to manual processes multiplies errors and coordination overhead. The bottleneck is the process, not the people.
§ 03 / What I Build
Business-focused web applications with clean, consistent interfaces.
I don't ship "another CRUD app" Every system is shaped to the operation it serves.
01Inventory, purchasing, operations
ERP Systems
Stock movements, purchase orders, supplier ledgers, multi-warehouse transfers and the daily operations that keep a business running. Built around your actual workflow, not a generic template.
02Dashboards, workflows, admin panels
Internal Tools
Back-office tools your team actually opens every morning. Approvals, queues, search, exports, role-based access. Designed for speed and clarity, not show.
03Employees, projects, reports
Business Management
HR records, attendance, project tracking, time logs, and reporting. Centralize the data you currently juggle in spreadsheets and chat threads.
04Metrics, exports, visualizations
Data & Reporting
Live dashboards, scheduled reports, KPI tracking. Turn the data your systems already produce into decisions, without the spreadsheet shuffle.

§ 04 / How it works
A clear, four-step process. No surprises.
Most clients haven't hired a developer before. This is how we go from "we need a system" to a system your team uses every day.
- ▸ 01
Discovery
We walk through your business process and the problems the system needs to solve. I listen more than I talk.
- ▸ 02
Plan
I define the features, workflows, roles, and data structure, and send a fixed quote and timeline for your approval. You get a clear scope and a real number before any code is written, so you know it fits your budget.
- ▸ 03
Build
I develop the application in short cycles, with regular previews so you can react early, not after launch.
- ▸ 04
Launch
We run final tests, settle the final payment, deploy, and onboard your team. Documentation is built in, not billed separately.
Typical timeline. 4 to 10 weeks depending on scope.
§ 04 / Frequently asked
Answers to the usual questions.
Still not covered? Send it in the form below. I'll reply personally.
Yes. The first call is no-cost and no-obligation, just a conversation to see if we're a fit.
Most small ERPs and internal tools take 4 to 8 weeks end-to-end. Larger systems with multiple modules, integrations, and rollout typically run 8 to 16 weeks. I always give a timeline after the discovery call, not a sales estimate.
It depends on the modules, workflow, and how much of your process is unique. A focused internal tool starts much lower than a multi-module ERP. I scope per project after discovery so you know the real number, not a guess.
Unfortunately, I don't take on projects involving existing systems developed by others. I build and maintain the systems I deliver to ensure they meet my quality standards. Since I can't guarantee the quality, structure, or reliability of an existing system, working on it could introduce unexpected issues. I also provide free bug fixes for issues related to my own work, which is part of my service commitment. For these reasons, I focus exclusively on building systems from the ground up.
Yes. I handle deployment to a host of your choice (DigitalOcean, AWS, Render, Cloudflare, Vercel) and set up CI/CD, backups, and the domain. For most business internal tools, I recommend deployment in Cloudflare, Render, and Neon.
Yes. Bug fixes are free and feature changes will be scoped and quoted accordingly. Clients may handle it with their in-house IT and call me when they need extra hands.
Yes. Systems I build are structured to grow. Adding a new module, a report, or a third-party integration is a normal request, not a rewrite.
