Production-Grade PHP/Symfony Systems
I build backend architecture for products handling millions of users. APIs, integrations, databases — designed to scale and maintain.
Senior PHP/Symfony Developer · Freelance · Remote · Flexible Timezone
I turn business needs into software that works — and keeps working as it grows.
Currently available for new engagements
Over a decade with a Dutch product company. A patient portal with 2.5M+ users. Billing systems handling real revenue. I build software that works — and improve it while it's live. Available for freelance, contract, or B2B — remote, flexible timezone.
Freelance / contract
What I bring to a team.
Complex Business Logic, Clean Code
Billing, healthcare portals, booking platforms — I turn messy business rules into clean, maintainable software.
Seamless Remote Collaboration
Over a decade working remotely with international teams. Clear communication, independent delivery, timezone flexibility.
Zero-Downtime Modernization
I modernize live systems incrementally. No risky rewrites. Your users never notice the upgrade — they just get a better product.
Profile
Remote from India. EU hours. Product work that lasts.
I build and improve software that businesses depend on — patient portals, billing systems, booking platforms. My job is to deliver working solutions, connect them to the rest of the business, and keep shipping new capabilities without disruption. I'm a senior PHP/Symfony developer. But beyond the tools, what I deliver is this: I understand your product, your users, and your business — then I build software that makes your company safer and faster to grow. Over a decade with a Dutch product company and international teams, working remotely from India with flexible timezone overlap. Before that, fourteen years at IndiaNIC, growing from developer to senior engineer on commercial platforms. I value long-term product relationships — not short visits.
What others say
Recommendations.
"Kaushik is the definition of a dependable Symfony developer. Having worked together for years, I've seen firsthand their ability to deliver results consistently every single day. They adapt quickly to changing requirements, tackle unexpected challenges with great resourcefulness, and always maintain high standards for their work."
"Kaushik is reliable on assigned backend work. When the task is clear, he builds the backends, adapts existing systems, and delivers the work that was asked of him. A large part of his work has been on live products that people already use."
ZwangerenPortaal — Healthcare Platform (2.5M+ Users)
PHP/Symfony backend on a Dutch patient portal used by over 2.5 million new parents. The value is continuity: the product stays live while architecture and APIs improve.
Biller / Inqonto — billing platform
Modular PHP billing: invoices, recurring charges, reminders, timesheets, VAT and PDF — structured so the product could grow without collapsing into one script.
Benefit Boutiques — appointment booking
Customer-facing PHP booking for boutiques: backend and UI, delivered as a live scheduling product.
How I work
Independent. Clear. Product stays up.
Understand the Problem First
I learn your system, your users, and your goals before writing code. Every change I make solves a real problem.
Ship Without Risk
I deliver in small, tested increments. Your product stays live, customers stay happy, and you see progress every week.
Leave Your Team Stronger
Clear code, clear documentation, clear handoffs. I build solutions your team can own, extend, and maintain.

AI as a production concern
I am adding LLM skills the same way I ship backends: auth, failure modes, and maintainability — not notebook demos.
Modernising a live healthcare platform
How I sequence Symfony work when patients and professionals already depend on the system.
Billing belongs in the domain
VAT, reprints and access control are product rules. They should not live only in a PDF.
Career
Experience.
Senior Engineer — Freelance / Contract
LinkORB Engineering
Eleven years with a Dutch product company, overlapping European morning and afternoon hours. I help keep live products running and growing — including ZwangerenPortaal.nl, a patient portal used by millions of new parents.
Value to the organisation
- The product stays available while it still has to change
- New capabilities ship without a “stop everything and rewrite” moment
- Independent delivery, explained in language a European team can act on
- Long-running product work, not a short visit
Senior Engineer
IndiaNIC Infotech Limited
I owned commercial web products from the first conversation about the need through design, build, test and release. Clients got something they could run a business on — not only a technical design.
Impact
- End-to-end ownership of features on products that stayed in use for years
- Estimates and delivery that product teams could plan around
- Software structured so the next change was cheaper than the last
- Raised the bar for how work was explained and handed over
Developer
IndiaNIC Infocom Limited
I built and maintained production web applications: new features, fixes, and the data behind them. This is where I learned full-cycle delivery — a request from a client becomes something people can use.

Freelance and contract. Remote from India, overlapping European mornings and afternoons. I am strongest when a product already matters to customers and still has to grow.
