About this gig
Does your startup project take a long time to respond under heavier user traffic?
Are you concerned if your MVP can serve more users and still perform?
How can your platform support 10k, 100k or even more operations per second?
With over 20 years experience writing code and building scalable high performance applications I can help you get the right answers to these questions.
A few types of systems I worked on:
- Crypto Exchange: Designed and implemented a full solution
- AI chatbot startup: Scaled their MVP from crashing under 1000 req/s to <50ms latency under 50k+ req/s
- Social Media Platform: Designed their chat solution to work at scale

FAQ
What backend technologies do you cover?
In terms of programming language I currently focus mostly on Go, but previously I worked with NodeJs, Elixir and PHP. As for backend services I have experience with AWS, NATS, Apache Kafka, Redis, RabbitMQ, Postgres, MySQL, MongoDb, InfluxDB and TimescaleDB.
Can you also help implement the proposals from your audit?
Yes, however most system architecture decisions requires fundamental changes to existing codebases and can take some time to implement, test and roll out. I provide a one day add-on that you can use to handle more punctual issues we discuss and we can discuss if you need more time.
I'm at MVP stage. Can I still book the gig to get your input?
Sure. It's actually better since you plan to build a scalable solution from the start and not lose time, money and customer confidence to fix these later.
Should I contact you before booking the gig?
Yes, it is advisable to send me a message first so that I can get as much relevant information about your particular case before we start.
