During four months on VKCOM/kphp, G. Buteyko developed and enhanced core RPC infrastructure, focusing on cross-language serialization, protocol extensibility, and runtime observability. He implemented typed serialization and fetch APIs in C++ and PHP, enabling seamless integration of autogenerated PHP TL serializers and improving RPC function handling. His work introduced byte-level data handling, optional encryption, and IPv4/IPv6 support in the VK RPC protocol, strengthening security and compatibility. By aligning runtime interfaces and exposing fetcher positions, he improved debugging and traceability. Buteyko’s contributions demonstrated depth in backend development, compiler and network programming, and delivered maintainable, future-proof solutions for distributed systems.

January 2026: Implemented RPC Fetch Position API (fetch_get_pos) across all runtimes for VKCOM/kphp, exposing the current fetcher position in the RPC context to improve observability, debugging, and correctness of fetch-related tracing. The change aligns with existing runtime interfaces and is represented by commit e102230aa9c34f57cb00a4823799f9cdf00abc98 (fetch_get_pos in all runtimes (#1507)).

December 2025 was centered on stabilizing VKCOM/kphp's core RPC stack, delivering low-level data handling improvements, and extending protocol capabilities. Key outcomes include fixing a K2 compile blocker caused by a typo and cleaning up an unnecessary move, introducing byte-level granularity for internal RPC buffers with new APIs to store and fetch single bytes and strings, and adding VK RPC protocol version 1 support with optional encryption and IPv4/IPv6 compatibility. These changes improved build reliability, runtime efficiency, and security, enabling more robust communications and smoother maintenance. Demonstrated strengths in C++ systems programming, security considerations, and cross-address-family support, translating to business value through reduced maintenance costs, faster feature delivery, and stronger security posture.

October 2025 monthly summary — VKCOM/kphp Key features delivered - PHP-based TL serializer execution path for RPC: added support for autogenerated PHP TL serializers within the typed TL builtins. - RpcFunction interface and related implementations updated to support custom fetchers for TL serialization/deserialization, enabling PHP-based serialization logic integration. Major bugs fixed - No major bugs reported this month; work focused on feature delivery and integration stability within the RPC TL serialization path. Overall impact and accomplishments - Extends RPC flexibility and cross-language integration, enabling PHP-based serializer logic to be integrated directly into RPC calls, reducing custom wiring and accelerating PHP codepath adoption. - Establishes a foundation for further ecosystem expansion (additional serializers, tests, and docs). Technologies/skills demonstrated - PHP-based TL serializer integration, RPC architecture, TL builtins, and fetcher pattern. - Code governance: commit traceability (#1402; commit 3a3b1429130b43821421623b14322495aefcf6d6).

Month 2025-09 — Focused on strengthening tl2php RPC integration and RPC function handling, delivering code-generation and runtime enhancements to improve serialization, typing, and extensibility of remote procedure calls. Primary deliverable was the tl2php RpcFunction serialization method stubs, with added typedStore and typedFetch methods on RpcFunction implementations, and a new getTLFunctionMagic entry to improve RPC handling. The engine module was expanded with additional RPC functions and types to broaden capabilities and future-proof RPC usage. These changes provide stronger cross-language interoperability with PHP clients and lay a foundation for more robust, maintainable RPC workflows.
